Service Information

Maintenance Philosophy

Various equipment within the Dimetra Enhanced Base Transceiver System (EBTS) has been designed with a Field Replaceable Unit (FRU) concept to minimise system down time. Faulty FRUs may be quickly and easily replaced with replacement FRUs. This helps to quickly bring the system back to normal operation.

Due to the high percentage of surface mount components and multi-layer circuit boards, field component-level repair is discouraged for all equipment. The European System Management Centre should be contacted for further troubleshooting and repair.

Service and Replacement

Each FRU has a bar code label attached to its front panel. This label identifies the assembly’s sequential serial number. Log this number whenever contacting the European Systems Support Centre. For complete information on ordering replacement assemblies, or instructions on how to return faulty assemblies for repair.

Call Management Centre

Customers within the EMEA region should contact the Call Management Centre for all Service related enquiries unless they have alternative contractual arrangements. Enquiries to the centre will be allocated a tracking number and will be routed to the relevant department within Motorola. The Call management Centre operates a 24 hour by 7 day service.

EBTS System Overview

System OverviewDimetra is a digital communications system which provides the dispatch features defined in the TETRA (Terrestrial Trunked Radio) standard. Dimetra provides a concept of a wide-area trunked communications system, where an RF coverage area is a provided by number of Remote Sites connected to the Network Infrastructure.

The system allows users with mobile and portable subscriber units to communicate with one another and the Public Switched Telephone Network (PSTN) using the RF system as the medium. The RF system consists of strategically located Enhanced Base Transceiver Systems (EBTS) which are linked to the Network Infrastructure. The Network Infrastructure in turn provides the connectivity to the PSTN.

Private dispatch calls, group dispatch calls, private full-duplex calls and full-duplex mobile to land, land to mobile and mobile to mobile telephony calls, Short Message Service (SMS) and Packet Data services are all supported.

The network elements that constitute the Dimetra system are fully managed, allowing remote configuration and maintenance of the system.

Dimetra IP System Overview

The Motorola TETRA network solutions, Dimetra IP, are based on existing proven technologies that have been modified as appropriate to support the TETRA standard.

The Dimetra IP system provides telephone interconnect, two way dispatch and data services for private and public safety networks.

Dimetra-P features include:

• Voice Services

• Data Services

• Supplementary Services

• Dispatch Console Operator Features

• Dispatch Console Management Features

• Radio Control Management Features

• Network Management Features

• Mobile Station Features

Mobility Management is fully supported to allow continuity of service as subscribers move through the network coverage area.

The network elements that constitute the Dimetra IP system are fully managed, allowing remote configuration and maintenance of the system.

The Dimetra IP System elements can be broadly divided into those elements that provide interconnect (telephony) functionality, those that provide dispatch functionality, those that provide system connectivity and those responsible for system element management.

EBTS System Overview

Figure 1-1 Dimetra IP System Block Diagram

EBTS Platform

The TETRA EBTS consists of the Site Controller, an Environmental Alarm System, one or more Base Radios (BR), and a radio frequency distribution system (RFDS).

The EBTS provides the interface between the mobile radio units within the Dimetra system and the rest of the network. The main functions of the EBTS are listed below:

• Base Radio Transceiver

• Radio link formatting, coding, timing, framing and error control

• Timing control supervision to mobile stations (timing advance)

• Radio link quality measurements (Signal Quality Estimate)

• Site to site frame synchronisation

• Interface translation - radio link to network “land” equipment

• Switching functions between base transceivers

• Operation, maintenance and administration agent

It is possible to equip the EBTS with a redundant Site Controller to permit continued site operation should the primary Site Controller fail.

The Site Controller (TSC) controls the BR’s via an Ethernet LAN. The Dimetra IP EBTS uses an X.21/E1 connection for communication with other network elements.

In Dimetra IP systems the Site Controller may be configured to control a redundant Base Radio to provide back-up Base Radio operation, in the event of a Base Radio failing. If configured this

EBTS System Overview

Base Radio can also be switched in by the Central Network Equipment (CNE) to provide extra capacity. This feature is configured by the TETRA EBTS Service Software (TESS). The redundant BR feature requires an Auto Tune Cavity Combiner (ATCC) to operate, as the standby BR must be able to configure itself to the radio frequency used by a failed BR. In systems with multiple ATCCs, minimum channel separation must not only be maintained between channels on each ATCC, but also between channels of all ATCCs. This allows the redundant BR to be able to replace any failed BR and allows the redundant BR's ATCC to maintain correct channel separation. Note that, only the last BR in the EBTS may be configured as the redundant BR.

The EBTS works in conjunction with the mobile stations to make measurements that are used in the handover decision process when interconnect calls are in progress and the mobile stations are moving in and out of the EBTS coverage area.

The Dimetra IP EBTS is managed by the Zone Control Management (ZCM), communication between the EBTS and the ZCM takes place over the X.21/E1 link. The ZCM can download new configuration files to the EBTS and receive alarm/event and performance statistic information from the EBTS.

6866538D01-C 1 - 7February 2005

EBTS System Overview

Equipment CabinetThe EBTS Equipment Cabinet contains RF and control equipment. It provides the radio communication link between the land network and the mobile/portable units. The EBTS site consists of one cabinet (Primary Rack) or two cabinets (Primary and Expansion Rack).

EBTS System Overview

Breaker Panel

The Breaker Panel is mounted in the uppermost location of the Equipment Cabinet, as shown in Figure 1-2. This is the central location for power distribution and overload protection of the Equipment Cabinet.

Each circuit breaker is dedicated to a single module within the Equipment Cabinet. The circuit breakers provide manual on/off control for the modules, as well as providing automatic disconnect in the event of an electrical overload.

Junction Panel

The Junction Panel provides a central location for cabinet grounding and intercabling. Access to the Junction Panel is gained from the top of the Equipment Cabinet.

The Junction Panel is mounted at the top of the Equipment Cabinet toward the rear, as shown in Figure 1-2.

Cavity Combiner

The cavity combiner is a tuned 915-950 MHz transmit combining system for 4 channels.

The cavity combiner is mounted, as shown in Figure 1-2.

Receiver Multicoupler (RMC)

The Receiver Multicoupler (RMC) is an active receive multicoupler assembly that provides multiple receive signal ports. Each diversity branch antenna is connected to a module in the Receiver Multicoupler. Each RMC module is then correspondingly connected to one receiver in each of the BRs.

The Receiver Multicouplers are mounted below the Cavity Combiner, as shown in Figure 1-2.

Environmental Alarm System (EAS)

The EAS provides a central location for alarm signals into the EBTS site. The EAS provides an electrical interface to monitor such environmental conditions as site power, smoke detectors, and intrusion (burglar) detectors. Only one EAS is used per site.

The EAS also receives alarms from the Breaker Panel and the RFDS. Base Radio alarms are sent directly to the Site Controller over the Ethernet LAN.

The EAS accepts 48 alarm inputs and provides eight control outputs. The inputs are opto-isolated and sense contact closure between the alarm sensor and its return. Four RJ-45 connectors are used for the alarm connections within the Equipment Cabinet. The remaining alarm inputs and control (relay) outputs are accessible via two 50-pin subminiature-D connectors, one of which is accessible via the Junction Panel. The eight alarm outputs may be configured to respond automatically to certain EBTS state changes or to be manually controlled. The EAS contains its own power supply.

1 - 10 6866538D01-CFebruary 2005

EBTS System Overview

The eight alarm outputs are not supported with System Releases prior to D5.2.

The EAS module is mounted below the Receiver Multicoupler area, as shown in Figure 1-2. Alarm wiring is connected to the EAS via the junction panel at the top of the EBTS. Some of the connections are dedicated to specific equipment, although several inputs are available for assignment by the customer. The EAS interfaces with the Site Controller(s) via an IEEE 1284 interface.

Analog Power Monitor (APM)

The Analog Power Monitor monitors the forward and reflected power. The Analog Power Monitor Tray is located above the Cavity Combiner. The power monitor outputs a 0-5V voltage corresponding power levels between 0 - 320W.The first APM monitors the power of the Primary Rack, the second APM monitors the power of the Expansion Rack (if installed).

Site Controller (TSC)

The TSC assigns available frequencies and slots to the mobiles. It also communicates with the network via an X.21 or E1 link for Dimetra IP.

One TSC is required per EBTS configuration, the other TSC presence a redundance (the active and the standby TSC is linked via the 10/100BaseT Ethernet interface).

The TSC receives Global Positioning System (GPS) signals via the GPS interface, which it uses to develop high-precision system timing signals. The EAS interfaces with the TSC via the IEEE 1284 interface to communicate alarm signals from the EBTS to the network management centre. The Base Radios communicate with the TSC via the 10Base2 Ethernet interface.

The Site Controller supports the following I/O:

• One 10/100BaseT Ethernet port

• Three 10Base2 Ethernet ports

• Four T1/E1 connections

• One X.21 connection

• One IEEE 1284 parallel port (for connecting to the EAS)

• One front panel RS232 MMI

• Three time / frequency reference outputs

• GPS (internal receiver)

• RJ45 Serial

• RJ45 Redundancy

Figure 1-3 shows a block diagrams of the Site Controller and the I/O interfaces.

EBTS System Overview

DC Power Supply

The DC Power Supply provides conditioned DC operating voltages to the various Base Radio FRUs. It accepts an input voltage range of -41 to -60V.

Receiver

The Receiver provides the receive functions for the Base Radio. The receiver module contains three separate receivers to allow receive diversity using multiple receive antennas.

Exciter

The Exciter, in conjunction with the Power Amplifier (PA), provides the modulation and transmitter functions for the Base Radio.

Power Amplifier (PA)

The PA, in conjunction with the Exciter, provides the transmitter functions for the Base Radio. The PA accepts the low-level modulated RF signal from the Exciter and amplifies the signal for transmission via the RF output connector.

Each module is described in greater detail in Chapter 11, “Base Radio”.The BRs are mounted in the lower-most rack positions, as shown in Figure 1-2. The first BR is installed at the bottom of the cabinet. The next BR is installed above the first and each additional BR is installed above the previous one.

Safety Precautions

Introduction

Below is a brief summary of some of the safety precautions that should be taken into account when working with the EBTS. They are not exhaustive and all personnel should ensure they comply with any additional precautions applicable when using test equipment or facilities.

Static Sensitive Precautions

The static grounding wrist strap (Motorola P/N 4280385A59) must always be used when handling any board or module within the EBTS. Many of the boards or modules used in the EBTS equipment are vulnerable to damage from static charges.

Extreme care must be taken while handling, shipping, and servicing these boards or modules. To avoid static damage, observe the following precautions:

• Prior to handling, shipping, and servicing EBTS equipment, connect a wrist strap to the grounding clip on the Equipment Cabinet. This discharges any accumulated static charges.

Use extreme caution when wearing a conductive wrist strap near sources of high voltage. The low impedance provided by the wrist strap also increases the danger of lethal shock should accidental contact with high voltage sources occur.

• Avoid touching any conductive parts of the module with your hands.

• Never remove boards or modules with power applied to the unit (hot-pull) unless you have verified it is safe to do for a particular board or module. Make sure the unit will not be damaged by this. Several boards and modules require that power be turned off before any boards or modules are removed.

• Avoid carpeted areas, dry environments, and certain types of clothing (silk, nylon, etc.) during service or repair due to the possibility of static buildup.

• Apply power to the circuit under test before connecting low impedance test equipment (such as pulse generators). When testing is complete, disconnect the test equipment before power is removed from the circuit under test.

6866538D01-C 2 - 1February 2005

Safety Precautions / Recommended Tools

• Be sure to ground all electrically powered test equipment. Connect a ground lead (-) from the test equipment to the board or module before connecting the test probe (+). When testing is complete, remove the test probe first, then remove the ground lead.

• Lay all circuit boards and modules on a conductive surface (such as a sheet of aluminium foil) when removed from the system. The conductive surface must be connected to ground through 100k Ω.

• Never use non-conductive material for packaging modules being transported. All modules should be wrapped with static sensitive (conductive) material. Replacement modules shipped from the factory are packaged in a conductive material.

Any device (i.e., power supply) providing isolation between the mains and the EBTS must provide reinforced insulation to hazardous voltages. The DC power source providing power to the EBTS shall comply with requirements specified for a safety extra low voltage circuit (SELV) per EN60950, 1995.

Equipment has two independent power sources (A and B). To remove power from equipment, disconnect both power sources.

Always use appropriate lifting equipment and numbers of personnel when moving an EBTS equipment cabinet to reduce the risk of tipping. A fully configured equipment cabinet weighs approximately 276 kg (608 lbs). Tipping can result in serious injury and extensive equipment damage.

The Dimetra IP EBTS System Manual is intended for trained technicians experienced with Motorola base radio equipment or similar types of equipment.

The site controller board contains a lithium battery. Refer to local regulatory requirements for proper disposal.

Safety Precautions / Recommended Tools

ESD Wriststrap Safety PrecautionsAll EBTS platforms have had a small stainless steel bracket mounted on the front left-hand side, held by a metal surface screw.

The purpose of this bracket is to give a service or installation technician a point to which a wire from a wrist strap can be connected. This is for ESD (Electrostatic Discharge) protection.

The purpose of this TIB is to emphasise the need and the use of the ESD bracket and use of wrist strap.

The ESD point is a small bracket that is mounted with one of the screws that holds a unit.

• In PR3.2 it is placed in the front of the redundant TSC just above Base Radio 4. If there is no redundant TSC it is placed on a blank panel at the same position.

In order to make good electrical contact with the rack frame, the cage nut in which the screw is mounted is a special grounding type, which has “teeth” that cut through the paint of the rack frame. The screw that holds the bracket is made of steel, which is not painted black for the same reason.

There are two cases where special attention must be made.

1 Removal of the ESD point

The ESD bracket will have to be removed temporarily in two cases.

• Service of the redundant TSC.

• Installation/replacement of the entire Base Radio 4 (ESD bracket overlaps by 1-2 mm).

Replacing an entire TSC or Base Radio 4 does not require the use of an ESD wrist strap, as both boxes are ESD protected. However if any other service is required, the ESD bracket must be put back at the right position and with the right screw to enable the effective use of the ESD wrist strap.

2 Use of an ESD wrist strap and ESD earthing point

ESD wrist strap use is critical in the following cases.

• Replacement of any module inside a box. This includes service of any modules in a base radio.

• Service of Receiver Multicoupler (RMC). The RMC is a relatively open mechanical design and ESD protection is critical when servicing this module.

Special attention must be made to the cable that connects the (optional) CMU/duplexer tray RX outputs to the Low Noise Amplifier (LNA) inputs of the RMC. The LNA is made with a GaAs FET input, which by nature cannot be ESD protected. Never connect or disconnect this cable without using a correctly earthed ESD wrist strap.If The ESD bracket is removed in order to remove a complete FRU, attention must be paid to the position of the ESD bracket when it is restored. Also, the point must be restored for wrist-strap use.It is important that the ESD bracket is not moved to another position where the caged nut and screw is not of the type which makes electrical connection to the rack frame.

3EBTS Interface Commands

MMI CommandsMMI commands are input from a service computer to the system RS-232 serial port (19200 bps, 8 data bits, 1 stop bit, no parity). Depending on the task, the RS-232 port is accessed from the Site Controller, or from the front of each Base Radio Controller (BRC) in the Equipment Cabinet.

The service technician enters the MMI commands to communicate with the Site Controller at the system level. The system response is returned to the service computer via RS-232.

Various test procedures use these commands to test and configure the system. The test procedure for the Site Controller is in Chapter 6, “Configuration and Testing”.

Access Levels and ModesThe Site Controller and BR commands are available through the use of the password: motorola. This password allows the service technician access to a subset of the MMI command set for field service operations.

The motorola password is a default password that is programmed during manufacturing. The password may be changed via the MMI.

The Site Controller has a configuration mode MMI which provides facilities for setup and testing. The Dimetra IP Site Controller additionally has an MMI in application mode which provides local diagnostic information.

Most of the BR commands are valid only while the BR is in the test mode. The configuration data is temporarily stored in RAM until the BR is taken out of the test mode. Most MMI commands do not allow the configuration data to be permanently stored in EEPROM, although a limited number do. Commands that allow configuration data to be changed are noted.

6866538D01-C 3 - 1February 2005

EBTS Interface Commands

ConventionsThe syntax for each command is presented as follows:

• plain text shows the actual text to be typed to invoke a command or action

• italic text shows where a parameter or value is to be substituted

• text enclosed in brackets [ ] indicates an optional value that may be entered

• where items are separated by vertical bars | , the items are the applicable choices that may be entered

• text enclosed in braces indicates a corresponding selection or parameter that must be entered for the command to execute

• a series of dots ... indicates one or more occurrences of a preceding parameter

• a pair of dots .. indicates a range of valid values

The syntax for the Site Controller and BR commands is case sensitive. Each example is shown in the format that should be entered by the operator.

Some commands require the use of parameters. If input parameters are not entered, a response is returned identifying the proper syntax for the command.

A definition describes in detail each command’s purpose and function. Where helpful, the definition is followed by an example of the commands response. Typical values have been used whenever possible.

Some commands return varying responses (such as available, not available, unknown, o.k., and alarm). Only one of the possible responses is listed in each example.

3 - 2 6866538D01-CFebruary 2005

EBTS Interface Commands

Site Controller CommandsThe Site Controller commands consist of two groups: configuration and application. Both groups are individually described below.

The Site Controller may be accessed simultaneously via the front panel Service Access port and the rear panel SERIAL port.

Two access modes exist: unrestricted and restricted. In the restricted mode, a much reduced set of commands are available. These are the commands that have no effect on Site Controller operation (e.g., cls, dir, ver, help, logout).

If a user logs in to the Site Controller while another user is already logged in, the second user will gain access, but in the restricted mode. Warning messages are displayed when a second user logs in or logs out. Conversely, the evict command enables a user logged in under the restricted mode to force the logout of the other user, thereby gaining unrestricted access rights. The evict command is available only while logged in under the restricted mode.

The restricted and unrestricted modes can be differentiated by means of the prompt displayed. In the unrestricted mode an upper-case prompt is displayed (SC>), while in the restricted mode a lower-case prompt is displayed (sc>). Throughout this manual, it is assumed the user is logged in with the unrestricted mode, thereby having unrestricted access rights.

The Dimetra IP software consists of a boot-up Configuration Mode software program and an Application Mode software program.

The boot-up Configuration Mode software is responsible for:

- Boot-up and basic hardware configuration

- Allowing TSC and BRC config files to be loaded via TESS

- Providing MMI commands that support basic TSC configuration.

- Transferring control to the Application mode software. This normally occurs automatically after a ten second wait for users to log-in to the Configuration Mode MMI.

The Application Mode software provides the functionality and features that support normal EBTS networking operation.

PASSWORD

Syntax:

password

Upon entry of the password command, the user will be prompted to enter the existing password. A correct entry will result in a request for the new password, and the presentation of the restriction to which it must conform. If the entry is valid, the user will be prompted to re-enter the new password.

A message will then be displayed informing the user whether a change has been made. The command will change the appropriate password according to the newly entered password.

PBR

Syntax:

pbr address | -all

The pbr (“ping base radio”) command causes a message to be transmitted via Ethernet to the specified Medium Access Control (MAC) address. The Site Controller will display an appropriate success or failure message.

Options:

address MAC address in the format xx-xx-xx-xx-xx-xx where x is a hexadecimal digit.

-all Sends a broadcast ping to all BRs.

The MAC address can be obtained from a BR by using the BR MMI command get enet_id.

PING

Syntax:

ping [-n pkts_to_send] [-l data_size] [ip_address]

4EBTS Site Preparation andHardware Installation

Site Preparation

Site Planning

Proper planning helps to prevent potential on-site and off-site interference from other RF systems, and helps maximise system performance. Site layouts should always be planned to minimise the cabling lengths between RF equipment.

For full instructions and guidelines please refer to Motorola Standards and Guidelines for Communications Sites, R56, Document number 68P81089E50.

EBTS Site Survey

The site must be carefully inspected or surveyed using appropriate site survey forms before orders are placed for the equipment.

A technical representative from both the customer and the site owner should preferably be in attendance for total concurrence at a single given time.

In order to minimise any misunderstanding which may arise in the future, the survey report must be countersigned by all attendees at the site survey. The site survey should address all relevant issues involving the EBTS site installation. All involved parties should be in agreement on all of the issues before any work commences. The site survey issues are as follows:

• The potential location of the EBTS Cabinet, size of the equipment room, and the doorway or access into it. Access around EBTS shall include adequate clearance for cabinet front door opening.

• Verifying the suitability of the existing or proposed Heating-Ventilation-Air Conditioning (HVAC) and other environmental criteria in relation to the EBTS equipment. (See “Environmental Considerations” paragraph and Table 4-2, “Typical Power Loads and Heat Dissipation Values” later in this chapter.)

• The potential location of the power supply equipment.

• The power requirements for the site.

• A check of the history of local voltage and frequency variations together with the possibility of interruptions of the supply to the site.

• The standby power requirements for the site.

• The location of the mains power distribution.

6866538D01-C 4 - 1February 2005

EBTS Site Preparation and Hardware Installation

• The location of the Network Terminating Unit (NTU) for the X.21 or E1 leased line.

• The location of telephone and modem connections.

• The location of the building earth and the tower earth.

• Inspection/test of the building and tower earth.

• The suitability, space availability, and location of the cable entry point into the equipment room.

• The suitability, space availability, and location of the existing overhead cable tray or ladder rack.

• The suitability and location of the existing lightning arrestors.

• The suitability, space availability, and location of the existing cable tray or ladder rack between the equipment room and the antenna tower or the antenna system support structure.

• The space allocated on the tower for the antennas.

• Measurement or length estimation of all cable runs.

• Checking the access route into the equipment room.

• Identifying the type of tower and the type of structure on which the antennas will be mounted.

• Checking the access route to the site.

• Identifying any special conditions. For example:

• Access impossible in winter

• Access only with a security escort

• Access only by helicopter or all-terrain vehicle

• Identifying the site and equipment room key holder and the procedure to obtain the keys.

• Surveying the route the equipment will need to be taken between the closest point its delivery truck can reach and its final position in the equipment room.

• Identifying any civil works or changes required to the existing equipment room or the access to it.

• Identifying any Civil Works or changes required to the existing tower or antenna mounting structure or the access to it.

• Checking that the working light levels in the equipment room required during the installation and commissioning are adequate for the equipment, its cabling, and wiring to be installed and tested.

350 - 500 Lux is the level required in an office environment. If the light level is inadequate, allow for temporary lighting to be available during the installation and commissioning of the equipment.

• Establishing any special working conditions. For example:

• Only out of hours working permitted.

• Only 8 daylight hours working permitted.

• Site escort only permitted to work restricted hours.

• Special working conditions or designated holidays which are restricted by local regulations or statute.

• Verifying that the floor can sustain the weight of the EBTS site equipment.

EBTS Site Preparation and Hardware Installation

Site Considerations

The EBTS site building should not contain windows and must be able to resist extreme weather conditions. It should be designed to meet the requirements of any and all local building codes, and relevant regulations, applicable to the site location.

The DC Power supply for the EBTS has to be installed in the same building.

Motorola recommends the following considerations when selecting a site:

• For front access only stations allow a minimum of 80 cm for access.

• The minimum ceiling height of 2.4 m (7’11”) above a finished floor is required to allow enough space for the height of the equipment cabinet and cable access at the top of the cabinet.

• The ceiling structure should be able to support a cable tray assembly for routing the inter-cabinet cabling and other site cabling. The cable tray assembly is mounted to the site ceiling and walls per site plan and should be at least 2.2 m (7’3”) from the site floor to allow for the height of the equipment cabinet.

• The door dimensions should be at least 91 cm (3’) wide and 2 m (6’8”) high.

• All exterior doors should have tamper proof locks installed for security purposes.

• The operating range of the EBTS is -20 °C to +55 °C and therefore the site interior temperature must be maintained within these limits. Maintaining a stable, moderate site temperature is the best approach for long term reliability of the equipment. The equipment is not approved or intended for outdoor use.

• Proper surge protection is required for all antennas and power inputs to prevent potential damage to the site equipment.

• The site floor should be true to within 3.2 mm (1/8”) of any equipment footprint and be able to support the weight of the site equipment. Refer to the floor loading information provided in this chapter.

Cabinets

Cabinet Dimensions

The Equipment Cabinet dimensions are as follows:

• Width: 60 cm (23.6”)

• Depth: 60 cm (23.6”)

• Height: 1.845 m (72.64”)

6866538D01-C 4 - 3February 2005

EBTS Site Preparation and Hardware Installation

Cabinet Footprint

The equipment cabinet has a footprint as shown in Figure 4-1.

Figure 4-1 Equipment Cabinet Footprint

The equipment cabinet may be installed against adjacent equipment. Figure 4-2 shows the cabinet layout within a typical site, cabinets 2 and 3 are optional. At least 0.6 m (2’) of free space is required in front of the cabinet and at least 15 cm (6”) of free space is required behind. Additional free space is recommended at the back of the cabinet to greatly ease the removal and replacement of FRUs. Additional free space is also recommended at the front of the cabinet to allow service personnel easy access to the equipment.

Where there is no possibility to reach connectors at the rear of FRU's, it is possible to remove all FRU's from the front of the EBTS by pulling the FRU sufficiently forward (after loosening the retaining screws) to be able to grasp the connectors. In these cases it necessary to support the FRU while the connectors are tagged and loosened.

EBTS Site Preparation and Hardware Installation

Special Considerations

Breaker Panel Access

Adhere to local electrical codes and regulations regarding clearance for electrical service access to all fuse panels, breaker panels, etc. Typically, a minimum clearance of 91 cm (36”) is recommended. Additionally, all doors to this equipment should be able to open to at least 90°.

Hazardous Materials and Equipment

Compliance with all local and any other regulations concerning the handling and use of hazardous materials and equipment is the sole responsibility of the customer and associated agents.

Seismic Active Areas

EBTS sites that are in seismic active areas may require additional bracing of the equipment cabinet. This manual does not contain specific procedures related to seismic bracing.

X.21 Facility Interface

Surge Arrestor

Per any local regulations, a surge arrestor may be required at the X.21 service entrance. The arrestor should be designed for operation with a X.21 circuit. The arrestor typically is only installed on the customer side of the X.21 service entrance. It should be wired per manufacturer instructions.

Service Entrance

A rigid conduit sleeve must be installed to provide the service entrance into the site building. The conduit should be about 5 cm (2”) in diameter and a PVC elbow should be attached (pointing down) on the outside end of the conduit. The conduit must be grounded in accordance with the Motorola Standards and Guidelines for Communications Sites, R56, 68P81089E50.

Site Utilities Backboard

A standard receptacle outlet should be installed on or adjacent to the backboard. This outlet can be used for accessories, such as modems and other AC powered devices. This may also be used as a general service outlet.

E1 Facility Interface

Surge Arrestor

A surge arrestor must be installed at the E1 service entrance. The arrestor must be designed for operation with an E1 telephone circuit. The arrestor must only be installed on the customer side of the E1 service entrance. It should be wired per manufacturer instructions.

4 - 6 6866538D01-CFebruary 2005

EBTS Site Preparation and Hardware Installation

Service Entrance

A rigid conduit sleeve must be installed to provide the service entrance into the site building. The conduit should be about 5 cm in diameter and a PVC elbow should be attached (pointing down) on the outside end of the conduit. The conduit must be grounded in accordance with the Motorola Standards and Guidelines for Communications Sites, R56.

Site Utilities Backboard

A wall mounted AC grade fire-rated plywood backboard (12.7 mm x 122 cm x 122 cm) must be provided within the site. Reserve a two-square-foot area on the backboard for dedicated system use.

An approved AC mains receptacle outlet should be installed on or adjacent to the backboard. This outlet can be used for accessories, such as modems and other AC powered devices. It may also be used as a general service outlet.

Environmental Considerations

Temperature Control

The environment in which the EBTS operates is an important consideration. The temperature should be regulated to ensure trouble-free operation. Excessive temperatures result in generated heat that may reduce the life-span of electronic equipment, and could cause permanent damage.

To combat temperature problems, a Heating-Ventilation-Air Conditioning (HVAC) system may need to be used. All HVAC systems should be thermostatically controlled. The specified operating temperature range for the EBTS equipment is -20 °C to +55 °C. Optimum equipment operation occurs when the internal temperature of the EBTS site is maintained at 26 °C ±5.5 °C (78 °F ±10 °F). The environmental equipment must be rated such that it is able to maintain the environment to meet the equipment heat dissipation values, which are given in kilowatt-hours (kWh). Refer to Table 4-2 for additional heat dissipation information.

The EBTS equipment operates on a -48 VDC (positive ground) power system which typically includes batteries. Should AC power be lost, the DC power system continues to supply the EBTS equipment with the necessary power. Because the EBTS remains operational during loss of AC power, heat is still generated by the equipment. Unless the site HVAC is on a backup system, the generated heat will effect the operation of the EBTS equipment. As a protection mechanism, output power of the BRs is designed to decrease in the event that normal ambient temperature is exceeded.

For sites containing more than one-hour battery backup, the effect of generated heat should be considered. The HVAC system design should be evaluated to ensure the proper operating environment is maintained during loss of the AC power.

Redundant HVAC Systems

A redundant HVAC system may be installed, if necessary. It must be wired on a delayed circuit to prevent both HVAC systems from starting up simultaneously. The HVAC system should be capable of automatically switching between the heating and cooling modes in response to the thermostat. The controls must ensure that both modes never operate simultaneously.

6866538D01-C 4 - 7February 2005

EBTS Site Preparation and Hardware Installation

Existing HVAC Systems

Existing building HVAC systems may be programmed to turn off during non-occupied hours. This type of HVAC system must be evaluated to ensure that the site temperature is maintained.

Humidity

At 35 °C (95 °F), the relative humidity within the site should be less than 75% non-condensing. If the operating environment is subjected to large variations in humidity then special considerations has to be made if the system contains cavity combiners. The auto tune cavity combiner has a build in fine tune time out feature to compensate for humidity drift. Please refer to Chapter 10, “RF Distribution System (RFDS)” for the full explanation of this feature.

Corrosive Environments

The equipment should not be directly exposed to corrosive environments. If the equipment site is located in a coastal environment, proper air filtration for the site should be in place to protect the equipment from salt mist contamination.

Air Quality

For cabinet-mounted equipment operating in an area which is not environmentally controlled, the airborne particulates level must not exceed 90 µg/m3.

Electrical Requirements

All electrical wiring for the EBTS site must meet the requirements of any and all applicable local codes and regulations.

Any device (i.e., power supply) providing isolation between the AC mains and the EBTSs must provide reinforced insulation to hazardous voltages. the dc power source providing power to the EBTSs shall comply with requirements specified for a safety extra low voltage circuit (SELV) per EN60950, 1995.

Applicable Codes and Practices

The following list of codes and practices shall be adhered to when performing the installation:

• UK RPSG Installation Manual, System Quality Standard, specification number 2200, part no. 68P02200F01.

• UK Institution of Electrical Engineers (IEE) 16th edition of their Wiring Regulations (Appendix 12, “Cable Capacities of Conduit and Trunking”).

• Antenna System Installation Practice, issued by The Directorate of Telecommunications of the UK Home Office.

• Details of Earthing Requirements for Masts, Aerial Feeder Cables and Radio Equipment Rooms, issued by The Directorate of Telecommunications of the UK Home Office.

EBTS Site Preparation and Hardware Installation

AC Service and Power Supplies

Service Current Rating

The input current rating of the DC power supply equipment shall be considered when selecting the AC main service. When the facility HVAC is powered from the same panel or sub-panel as the DC power supply equipment, the total draw (including start-up current) shall also be accordingly considered.

The DC power system has normal loads and start-up loads, as does the HVAC. Both of these loads are dependent upon the number of Base Radios in the site and the size and condition of the battery system. The normal load of a typical power system is provided in Table 4-2 for several common EBTS configurations using a two hour backup. These loads may differ for customer designed power systems.

EBTS DC Current Load

Table 4-3 lists typical power consumption values for various components within the EBTS.

The Base Radio current draw value given below is the steady-state value at full BR transmit power. Instantaneous start-up current draw can be as high as 230 A, exponentially decaying to 25 A after 10 msec, and then stabilising at the rated current. This dynamic needs to be considered when selecting a DC power system.

6866538D01-C 4 - 9February 2005

EBTS Site Preparation and Hardware Installation

Emergency Generator and Transfer Switch

Some sites may contain permanently installed emergency generators, however, most telecommunications sites are equipped with connections for portable generators. Sites with permanently installed generators usually have an automatic transfer switch used to transfer the AC service from the utility power to the generator after the generator has started. Sites with connections for a portable generator require a manual transfer switch and external connector.

Generators and transfer switches must be capable of supporting the maximum load for the customer defined service area of the generator. Start-up loads that include the HVAC and rectifiers must also be taken into consideration when selecting a generator size.

The EBTS site contains an Environmental Alarm System (EAS) that has five assignable dry contact closures and multiple customer defined inputs. Permanent generator operation may be monitored by one or more of these inputs, if desired.

Surge Arrestors

Per local regulations, a surge arrestor may be required adjacent to the AC power panel. Very short wire lengths between the arrestor to the power panel are typically required for proper operation.

For sites using a transfer switch, the arrestor should be installed on the panel side of the transfer switch. Additional arrestors may also be installed at the customer’s option on the line or generator side of the switch.

Power Panel

Motorola recommends that all EBTS sites use a standardised power panel including circuit breaker layout. Vacant space should be left to allow for future requirements.

– 48 VDC Power System

The EBTS equipment operates on a DC power system that typically includes a -48 VDC battery system. A readily accessible power disconnect device (e.g., circuit breaker) for the EBTS should be incorporated into the fixed wiring.

To protect against excessive current, short circuits and earth faults in the -48 VDC power source, protective devices shall be included as part of the installation. The installation shall meet the requirements of any and all applicable local codes and regulations.

DC Power Reference

The EBTS equipment operates from positive ground, 48 VDC power. Reference is made throughout this manual to the -48 VDC and the DC return power leads. The -48 VDC and return leads are kept isolated from chassis grounds in the equipment.

The positive (+) return lead is grounded at a single point on the rectifier load return bus. Table 4-4 shows the typical colour coding for these wires.

Grounding Requirements

The methods and standards cited in the following paragraphs are typical. Local codes, statutes, regulations, and/or standards shall supersede any information provided herein, as applicable.

Where wire size is specified, the next-larger size wire shall be used where specified wire size is not available.

The EBTS site must meet certain specifications for adequate protection from lightning induced transients. Proper ground installation methods are outlined in the Motorola Standards and Guidelines for Communications Sites, R56. Refer to Quality Standards in Chapter 1 - Manual Overview for information on obtaining the R56 manual. The references cited earlier in this chapter shall also be followed.

Make sure that welding ground connections to the antenna tower does not void the warranty of the tower.

Metal monopole towers require a minimum of three 2.44 m (8’) long ground rods to be driven into the ground, spaced approximately 3 m (10’) apart. These ground rods may be exothermically welded to the bottom portion of the mast itself, to the monopole footing, or to the provided grounding connection tabs.

Site Building and Equipment Grounding

At stand-alone site buildings, a PVC (typically 20 mm (3/4”), or equivalent) conduit must be provided for the interior ground wire to exit the building. For site buildings with floors at ground level, the conduit must exit a side wall at a 45° angle or less. For buildings with space below the floors for a ground connection, the conduit may exit through the floor. In both cases, the location of the opening should be close to the master ground bar inside the building.

Use of metal conduit is discouraged as the conduit provides inductance to a surge, raising the impedance of the ground. If metal conduit is required by local building codes, both ends of the conduit must be bonded to the ground wire through the use of grounding clips or other suitable means to eliminate the inductance of the conduit.

Cabinet Grounding

Within the EBTS site, ground the cabinets with a single dedicated connection between the cabinet and the site safety grounding system. The EBTS equipment cabinet utilises a Rack Ground Bus bar (junction panel) to which the cabinet common ground connection to site safety grounding system is made. The minimum connecting wire size must be at least 35 mm2 CSA (#2 AWG) insulated copper wire. Typically, this wire shall use green (with yellow bands) coloured insulation.

Use two-hole mounting lugs (and split ring lock washers when possible) with an anti-oxidant grease applied for interior grounding connections and exterior secondary grounding connections. If lock washers are used, they should be placed between the nut and the lug to ensure the mechanical integrity of the connection. The washer must not be secured between the lug and the surface to which it is connected. Painted connections must be scraped clean before applying the anti-oxidant grease and lug.

Never use a bare or damaged wire for the connection of chassis ground or other electrical wiring. damage to equipment or potential injury to personnel could result.

The equipment cabinet frame must be connected to the site ground using a single dedicated ground wire.

The site ground wire should drop into the top of the cabinet and be connected to a single designated grounding stud. Single hole lugs (13 mm (1/2”) diameter) are used for these grounding connections.

4 - 12 6866538D01-CFebruary 2005

EBTS Site Preparation and Hardware Installation

The EBTS equipment cabinet is classified as a surge producer due to external coaxial cable connections. Surges from outside the site can enter the site grounding system via the coaxial cables. To prevent damage to the equipment, the cabinet must be connected to chassis ground through a minimum wire size of at least 35 mm2 CSA (#2 AWG). Green (or green-yellow) insulated wire must be used to identify all ground wiring.

Cable Tray Grounding

The cable tray assembly must be designed and installed so that it does not come into contact with metal conduits, pipes, or other metal objects. The cable tray assembly must also be connected to the building earth through the use of a single dedicated wire. The connecting wire shall be a minimum size of 16 mm2 CSA (#5 AWG) green (or green-yellow) insulated copper wire.

Any metal-to-metal joints on the cable tray assembly must be bonded together with a wire jumper to prevent electrical discontinuity, unless the tray connectors are specifically designed to ensure continuity. Painted surfaces on the cable tray assembly must be scraped clean at the point where the jumper wire is attached to ensure a good electrical connection. Repaint cable tray assembly surfaces, if necessary.

Electrical System Grounding

The site electrical system should be connected to the rack ground bar (junction panel provides RGB function) by a single connection. This should be from the panel/sub-panel in the equipment room with a 35 mm2 CSA (#2 AWG) stranded insulated wire (typically green, or green-yellow, insulation). For sites with sub-panels, the utility green Multi-Grounded Neutral (MGN) wire may not be present. In this situation, an electrician may need to be consulted to extend the MGN from the service entrance to the sub-panel. If this is done in metal conduit, then grounding clips should be used at both ends of the conduit to minimise inductance.

If metal conduit is used for the electrical system, all connections must be bonded together through conduit compression or screw fitting designed for such purposes. The metal conduit system must not be in contact with other metal on the site including cable ladder or equipment cabinets to minimise ground loops and sharing of surge energy. Small pieces of rubber or other insulating material may be used on conduit clamps to eliminate any inadvertent connections.

Ensure a good connection between the electrical system ground and site ground to prevent excessive voltage potential between the two ground systems during lightning strikes.

Power Supply and Battery Racks

Both the power supply rack and battery system rack should be individually connected to the internal ground bar. Typically, a 35 mm2 CSA (#2 AWG) insulated grounding wire with a single hole lug is used to make the connections. Refer to power supply equipment manufacturer’s manual for specific information regarding power supply equipment grounding.

DC Power System Grounding

The DC power system is grounded only at a single point to prevent return current flow through ground connections and ground loops. A 16 mm2 CSA (#5 AWG), or larger, insulated ground wire (green, or green-yellow) with a double hole lug should be attached in one of the locations on the DC return bus of the power supply rack. This ground wire is also connected to the Master Ground Bar.

6866538D01-C 4 - 13February 2005

EBTS Site Preparation and Hardware Installation

The return bus on the power supply rack may be supported by red insulators. The colour red in these insulators has no significance.

Miscellaneous Site Grounding

A 16 mm2 CSA (#5 AWG) insulated ground wire may be installed within the site to connect the miscellaneous metal items (such as the door, door frame, or HVAC grills) that are not likely to be the source of electrical surges. All ground wiring should be routed near the ceiling, if possible.

One end of the ground wire must be connected to the building earth. This connection bonds the remaining metal (conductive) items in the room with the ground system.

Ground Bars

There are two types of ground bars used in the EBTS site. Both ground bars should be mounted immediately below the antenna entry plate on both the inside and outside of the shelter wall. The ground bars must have direct wire connections to the site ground system.

Exterior Ground Bar

The Exterior Ground Bar (EGB) provides a convenient location to terminate coaxial grounding straps and grounding wires from exterior metal surfaces as they enter the site, including:

• cabling entrance plate

• cable support

• air conditioner housing

Building Earth (Master Earth Connecting Bar)

The building earth should be located inside the equipment room preferably underneath or near the cable entrance. Various metal structures within the site connect to the building earth, including the ground wires from:

• EBTS equipment cabinet

• power supply rack

• battery system rack

• DC power system return

• RF surge arrestors

• electrical system

• cable ladder/ceiling support system

• other miscellaneous metal items and structures (door, louvers, etc.)

Motorola recommends the use of 6.35 mm (1/4”) thick copper ground bars (or equivalent) with hole patterns to accept a minimum of 15 double hole lug connections (10 mm (3/8”) holes on 25.4 mm (1”) centre). The ground lead from the ground bars to the ground rod system should be a minimum of 35 mm2 CSA (#2 AWG). Both the internal and external ground bars must be connected together. This usually occurs when the internal ground wire exits the building and is tied into the ground rings with the external ground wire.

For sites which are part of an existing building, a connection to the building steel may be made in lieu of an underground ring. All other aspects of site interior grounding remain the same.

Antenna Installation

Antenna Systems General Installation Requirements

The following is a list of general practices that shall be considered when installing antennas.

1 All site precautions specifications involving aerial rigging must be followed to the letter.

2 Under no circumstances shall the tower be climbed or worked on if thunderstorms are occurring or even if they are forecast to occur in the general area.

3 Under no circumstances shall the tower be climbed or worked on if the temperature is below 5 °C (41 °F), or if there is ice on the structure of the tower.

4 All work on the tower shall be carried out in daylight.

5 Using a milliohmmeter, check that the tower earth is < 1.0 Ω, then check the building earth. If either is greater than 1.0 Ω, then inform the site owner and the customer, as this must be rectified by the site owner/administrator before any equipment can be installed.

6 Install the receive antennas on standoffs at the same recommended height, such that there is one on each leg of a triangular tower with at least 6 m (19.6’) horizontal distance between each.

7 Install the Transmit antenna on the top of the tower (where possible).

8 Install the GPS antenna in the agreed position, which may be lower down the tower.

9 Using a Time Domain Reflectometer (TDR), check that each drum of antenna feeder cable and jumper cable is undamaged.

10 Install the five antenna feeder cables, securing them with a cable clamp or cleat every 1.0 m (3.28’), then install an earth clamp on each at the top and bottom of the vertical run of cable.

11 Connect each of the earth clamps to the tower earth using the earth cable and ring terminals.

12 Install the five lightning arrestors in the cable entry plate, then install the plate in the equipment room cable entry point.

13 Using appropriately sized earth cable and ring terminals, connect the bond stud on the cable entry plate to the building earth in the room.

14 With a milliohmmeter, check that the earth connection between the cable entry plate and the building earth in the room is < 1.0 Ω.

15 Install cable connectors on the end of the antenna feeder cables. Then, connect each to one of the five lightning arrestors on the outside of the cable entry plate.

16 Install an earth clamp on each of the antenna feeder cables within 100 mm of the connector into the lightning arrestor. Then, using an appropriately sized earth cable and ring terminals, connect the each clamp to the bond stud on the outside of the cable entry plate.

17 With a milliohmmeter, check that the earth connection between the cable entry plate and each earth clamp on the cables is < 1.0 Ω.

18 Install the five jumper cables with their connectors on the inside of the lightning arrestors inside the equipment room, if the internal cable tray is not installed.

19 Using a TDR, check that each of the five antenna systems has been installed correctly and that none of the antenna feeder cables have been damaged during their installation.

6866538D01-C 4 - 15February 2005

EBTS Site Preparation and Hardware Installation

20 Make a copy of each TDR test to record the results.

21 Seal all the antenna cable joints against the ingress of dirt and damp with several layers of suitable sealing tape or compound.

22 Remove all pallets, packing, and cable drums. Clean the area.

Antenna Feed Line Requirements

The transmission line entry for all antennas should be installed with a metal antenna entry plate external to the site building. All cabling entry ports must be covered to prevent small animals or objects from entering. Transmission lines must be grounded to the exterior ground bar below the cabling entry port using manufacturer approved grounding kits.

To reduce interference (intermodulation) problems, connectors on the transmit antenna lines must be gold plated centre pins and a gold, silver, or ternary Cu-Sn-Zn alloy plated outer conductor. The plating on the male-female connector combination must match on both connectors. For example, a male connector containing a gold plated centre pin and silver plated outer conductor must match the female connector with a gold plated centre pin and silver plated outer conductor.

All connectors at the cabling entrance are Type N. Connector types at the antenna end may vary depending upon the antenna and jumper combinations selected by the customer.

Antenna Feed Line Identification

All antenna feed lines should be marked appropriately to simplify connections to the proper EBTS equipment. Coloured vinyl tape is recommended for use in identifying the antenna feed lines. Use 3M coloured outdoor marking tape or a permanent, colour-fast equivalent.

Antenna Surge Arrestors

All antenna feed lines should typically terminate with a suitable surge arrestor within 30 cm (12”) inside of the entry window. Each arrestor must connect to the master ground bar located below the entry plate. It is recommended that the arrestors be mounted to a mounting bracket to simplify grounding cable and installation.

Site Reference Operation Modes

The ETSI standard allows two modes of operation of adjacent cells: Synchronized and Non-Synchronized relative to the serving cell. The EBTS uses GPS to synchronize to the same time reference. For an adjacent cell to be indicated to be synchronized requires that both the serving EBTS and the adjacent cell are synchronized to GPS.

The EBTS can be configured via BTS Service Software for three different operating configurations, which control the synchronisation mode:

• Normal Synchronized Configuration (NSC):

This configuration is used to specify that the EBTS should only operate in synchronized mode relative to GPS. If the GPS reference is lost the EBTS will reset at the expiry of a configurable free-run timer and will then wait for the GPS to be restored before resuming operation. During operation the EBTS will however reflect the adjacent cell synchronization mode according to TETRA standard in the information to the subscribers.

• Automatic Synchronized Configuration (ASC):

4 - 16 6866538D01-CFebruary 2005

EBTS Site Preparation and Hardware Installation

This configuration is used to specify that the EBTS should operate in synchronized mode relative to GPS; however if the GPS reference is lost, the EBTS will continue to operate in synchronized mode for a configurable period (free-run time). If the GPS reference is not recovered in this time period, the EBTS will switch to non-synchronised mode. If an EBTS is started when no GPS reference is available, it will operate in non-synchronised mode.

Non-synchronized mode will not have optimized handover performance. When operating in non-synchronised mode all the adjacent cells will be indicated as non-synchronized with the EBTS. In order to re-synchronise an EBTS that is running non-synchronised it is necessary to perform a reset when the GPS reference is present. Prolonged operation in non-synchronized mode will eventually lead to critical alarms and the frequency accuracy of the EBTS will no longer be guaranteed.

To maintain the frequency accuracy it is necessary that the oscillator within the EBTS is periodically recalibrated. The periodic recalibration happens automatically when a GPS reference is present. The critical alarms indicate that re-calibration is due and should be performed without delay.

• Forced Non-Synchronized Configuration (FNC):

It is not recommended for System Release D5.2. The EBTS will always operate non-synchronized to GPS. The failure or lack of GPS will not be reported as an alarm. The EBTS will start up in non-synchronized mode regardless of the presence of a GPS signal. However if GPS is present the site reference is trained accordingly. Prolonged operation in this configuration without GPS will eventually lead to critical alarms and the frequency accuracy of the EBTS will no longer be guaranteed.

To maintain the frequency accuracy it is necessary that the oscillator within the EBTS is periodically recalibrated. The periodic recalibration happens automatically when a GPS reference is present. If no GPS reference is present, it will be necessary to perform the calibration manually. The critical alarms indicate that re-calibration is due and should be performed without delay.

It is possible to change configuration with BTS Service Software. The new configuration will only be active after an EBTS reset.

GPS Tracking Criteria

To allow a system to successfully initialise for the first time at a new location, the Position Dilution Of Position (PDOP) must be less than 10.0 (a low PDOP value indicates a low error (higher accuracy) in the position calculated by the GPS receiver).

PDOP is an accuracy factor which is a function of the relative positions of the satellites. If the satellites being tracked by the GPS receiver are within close relative proximity to each other, the resulting PDOP will be poor. Conversely, if the satellites are relatively far from each other, PDOP will be improved. Because any error in position results in a timing error in the BR transmission, the BRs are not allowed to key until the position error is acceptably low. Therefore, a site with a large PDOP value may incur a delay when the site is first initialised.

For Dimetra IP the position is actively monitored for 24 hours. The position with the best PDOP value over this period is selected as the final position, and is then permanently stored for future starts. The stored position will be reset each time Install is run.

Excessive PDOP values may be the result of the GPS antenna(s) not having an adequate “view” of the sky to initially determine its position. Motorola recommends locating the antenna(s) such that there is no PDOP values that exceed 10.0 for periods of more than 15 minutes. Once a system is operating and the site position has been stored, a PDOP of greater than 10.0 will not effect

6866538D01-C 4 - 17February 2005

EBTS Site Preparation and Hardware Installation

performance, as long as at least one satellite is being tracked. However, to maintain a maximum reliability, three satellites should be tracked at all times.

The system must be capable of the following:

• Tracking a minimum of four satellites during initial start-up

• Tracking three satellites continuously for maximum reliability.

GPS Evaluation Kit

The Motorola GPS evaluation kit can be used to evaluate the site and antenna mounting location prior to site acceptance. Although many GPS receivers are available, the Motorola GPS evaluation kit includes the same receiver and antenna used in the EBTS. The data reported by this kit is the same as that used by the EBTS, if the antennas were installed in the test locations.

The evaluation kit includes software programs and the instructions necessary to collect the necessary data in order to evaluate the site. The necessary data includes:

• Dilution Of Precision (DOP)

• DOP Type (Position or Horizontal)

• Number of visible satellites

• Number of satellites being tracked

GPS Start Up

The times given below are from applying power to the system to the frequency locked LED illuminating. GPS start up is the significant contributing factor in determining System Start Up times

• Initial Start:This is the first time an EBTS is powered on or after the Almanac or Position information has been erased from Non Volatile Memory. The site needs to locate 4 satellites and then train the reference oscillator from an unknown state.

• Warm Start:The EBTS has been previously powered up and the Non Volatile Memory contains valid Almanac and Position information and the reference oscillator was trained prior to starting the site. The times quoted are for a power off restart a software restart will be slightly faster.

• Soft Restart:This is a BTS restart where power is maintained during the reset, e.g remote BTS restart after software upgrade. The GPS receiver will continue to track satellites during the BTS restart, thus eliminating the ‘search for satellites’ phase of start-up.

4 - 18 6866538D01-CFebruary 2005

EBTS Site Preparation and Hardware Installation

If these start-up times are exceeded then follow the procedures for GPS Site Controller fault indications section

GPS Antenna Requirements

The antenna must be mounted high enough to clear the peak of the EBTS site roof. For systems in the northern hemisphere, the GPS antenna should be mounted so that a clear view of the southern sky is maintained.

Isolate the GPS antenna from RF interference by mounting the antenna at least 3.7 m (12’) horizontally from other transmitting antennas.

Adjacent structures, such as trees or buildings, are obstructions due to their wide, solid profiles. Mount the GPS antenna to clear these obstructions and provide a clear path. Adjacent antenna towers at the RF site which protrude into the required view have a minimal effect on GPS satellite reception and are not obstructions.

The colour coding schemes identified within this manual are a recommendation only. The purpose for identifying specific colours is an attempt to obtain uniformity between EBTS sites. Other colour schemes may be used.

GPS antennas are colour-coded yellow. The same identification technique used for RF antennas is also used to identify the GPS antennas, refer to Table 4-6.

6866538D01-C 4 - 19February 2005

EBTS Site Preparation and Hardware Installation

GPS Antenna Line Loss

The maximum allowable line attenuation between the antenna and the Site Controller GPS Receiver (GPSR) input is 6 dB. There is an additional 4 dB of attenuation for foliage. In a typical EBTS installation using 1/2” low density foam coaxial cable (or equivalent), the length of the cable run should never exceed 46 m (151 ft). This is sufficient for most installations.

When considering the use of longer cables, calculate the cable lengths allowing 4.5 dB of loss at 1.5 GHz (the GPS receiver frequency). The remaining 1.5 dB of attenuation is provided by interior site cabling and connectors.

Remote GPS (RGPS) Installation Verification

If a remote GPS is installed, the Site Controllers perform the following steps during GPS training when the TSC Application starts up (Dimetra IP):

• Attempt communication with an internal GPS receiver. If an internal GPS receiver is found then GPS satellite tracking will commence. The status sri -gps command will report the GPSR Type as ‘INTERNAL’.

• After approximately ten seconds of attempted communication to the internal receiver power is applied to the external receiver. The cable delay is measured (a process which takes approximately 18 seconds) and communication occurs with the external GPS receiver. If successful the status sri -gps command will report the GPSR Type as ‘EXTERNAL’ and also display the cable delay.

If neither an internal nor external GPS receiver is found then the search resumes for an internal GPS receiver. During the search process the status sri -gps command will report the GPSR Type as ‘UNKNOWN’.

Figure 4-3 Mating View of Remote GPS Receiver

Independently Powered Remote GPS units

On certain EBTS sites an RGPS receiver with an independent power supply may be used (for example fiber optic connection to the RGPS receiver). When using an RGPS receiver there is a transmission time delay proportional to the distance of the RGPS receiver to the EBTS. For a independently powered RGPS receiver with cable length greater than 500 m this time delay

4 - 20 6866538D01-CFebruary 2005

EBTS Site Preparation and Hardware Installation

cannot be automatically calculated by the TSC and needs to be entered manually via the TSC Application MMI.

During installation of the EBTS the time delay value will be manually measured and should be known to the user. The time delay is entered via the TSC MMI using the 'rgps_delay' command which is used as follows: rgps_delay -set xxx (See Chapter “EBTS Interface Commands” for full description of rgps_delay) where xxx is the time delay measurement in nanoseconds. In order for the independently powered RGPS receiver to operate correctly a time delay must be entered otherwise the TSC will assume that a normal GPS receiver is installed.

The TSC must be reset after a new time delay has been set.

Alarm Wiring

Various alarms or sensors are installed within the EBTS site building. All alarm wiring terminates at the Environmental Alarm System (EAS) located within the Equipment Cabinet. The electrical contacts for the alarms must be dry contacts and remain normally closed (open on alarm).

Motorola recommends site installation of the following alarms:

• Smoke detector (line powered)

• Intrusion alarm

• High temperature sensor

• Low temperature sensor

The high temperature sensor should be capable of monitoring temperatures above 27 °C (80 °F). The low temperature sensor should be capable of monitoring temperatures below 21 °C (70 °F). Temperature sensors should be mounted to the utilities wiring board at a convenient height to facilitate the setting and inspection of the trigger points.

Local codes may require an additional contact closure to deactivate the HVAC system and prevent circulation of smoke in the event of a fire. An additional smoke detector may be used to provide this contact. It can also be configured to trigger an external alarm, if required.

If a second alarm closure is used, it must be completely isolated from the dedicated EBTS smoke alarm circuit. Parallel connection of the HVAC controller through these contacts may damage the HVAC and EBTS equipment. This is because the HVAC low voltage controller typically has 5 VDC negative ground, which opposes the -48 VDC EBTS supply.

If specialised automatic fire suppression systems are installed within the site, water flow alarms or Halon release alarms may also be required. These systems may also have to be remotely monitored for unattended facilities. Check local codes for additional information and requirements.

EBTS Site Preparation and Hardware Installation

Receipt of Equipment

Equipment Inspection

Inspection of the EBTS equipment must be performed as soon as all equipment is unpacked.

If obvious damage has occurred to the shipping containers before unpacking, contact the shipping agent and ask that a representative of their company be present while the equipment is unpacked.

Observe guidelines for safe handling of electro-static sensitive devices or equipment to prevent electro-static damage. An anti-static wrist strap is provided with the EBTS and should always be worn when handling any electrical component.

Inspect the following upon receipt of the EBTS:

• Check for loose or damaged equipment

• Check all sides of the cabinet for dents, scratches, or other damage

• Check all cabinet wiring to ensure connections are in place

• Check modules and boards for physical damage to controls or connectors

• Verify that ground straps are secure

If any equipment is damaged, contact the shipping company immediately, then your Motorola representative.

Equipment Inventory

Check the EBTS equipment against the itemised packing list to ensure that all equipment was received. If available, check the sales order with the packing list to account for all equipment ordered. Contact your Motorola representative to report missing items and for additional information.

EBTS Site Preparation and Hardware Installation

Hardware Installation

Installation Overview

The procedures described in this chapter assume the field technician or installer has knowledge of the installation techniques contained in the Motorola Standards and Guidelines for Communications Sites, R56.

Prior to performing the installation procedures, prepare the site with all associated antennas, communications lines, and other related site equipment.

Installation procedures provided in this chapter cover the EBTS Equipment Cabinet. In an EBTS site, the term “cabinet” is a generic term used to refer to Fixed Network Equipment (FNE) mounted in different types of frames. It does not refer in any way to building electrical cabinets, outdoor utility cabinets, or some types of equipment shelters commonly known as cabinets.

The Equipment Cabinet uses a Schroff Eurorack, which is referred to as a “1.9-metre cabinet”. This cabinet ships standard as an open frame with four corner posts with top and bottom assemblies to tie the posts together. Actual cabinet height is 1845 mm but also a 50 mm lifting eye on the top of the cabinet would give a total height of 1895 mm.

Personnel Considerations

The following personnel will typically be required to install an EBTS site:

• A working Installation Supervisor.

• A minimum of two Installers per EBTS site. (Two Installers could include the working supervisor, provided there is a minimum of two persons on each EBTS site at all times.)

• Two Aerial Riggers to install the antenna system.

• A Commissioning Engineer (attends only during the commissioning stage).

Transportation of the Equipment

It is recommended that to move and locate all the equipment in its final position, or in the case of securing antenna systems to the base of the tower or structure on which the antenna systems are to be mounted, a transportation company specialising in the moving of heavy electronic equipment should be used.

EBTS Site Preparation and Hardware Installation

Lifting Equipment Rack

Safety Considerations

Crush hazard could result in death, personal injury or equipment damage. Equipment racks can weigh up to 545 kg (1,200 lbs.). Follow instructions below for proper lifting procedures.

Equipment racks should only be lifted without the use of lifting equipment when there are sufficient personnel available to ensure that regulations covering Health and Safety are not breached.

Motorola recommends the use of appropriate powered mechanical lifting apparatus for moving and lifting the equipment racks.

In addition to these points, refer to and comply with any local regulations that govern the use of lifting equipment.

Lifting Equipment racks from Horizontal

In some cases the equipment racks are laid down horizontal to facilitate the shipping process. Use appropriate lifting apparatus to lift the racks upright complying with all applicable health and safety regulations and any other regulations applicable to lifting heavy equipment.

Crush hazard could result in death, personal injury or equipment damage. Do NOT use eyenuts to lift the rack upright from horizontal position. Eyenuts could fail resulting in the equipment dropping.

Do NOT use the eyenuts mounted on top of the rack to lift the equipment upright from a horizontal position. The eyenuts are NOT designed to lift in this direction and could fail resulting in the equipment dropping.

Lifting Equipment Racks Vertically

If it is necessary to lift the equipment rack vertically, four (4) M10 eyenuts are provided mounted to the top of the rack. Before attempting to use, visually check the eyenuts and associated rack hardware for damage that may have occurred during transit. If any damage is apparent, DO NOT USE; contact Motorola for replacement.

4 - 24 6866538D01-CFebruary 2005

EBTS Site Preparation and Hardware Installation

ALL four (4) eyenuts MUST be used when lifting the equipment rack. When lifting from a center point, the distance from each eyenut to the lifting point must be minimum 40 inches (1 meter) to ensure the proper lifting angle is maintained (see Figure 4-4). Using a length shorter than that specified could cause the eyenuts to fail.

If eyenuts are removed or become loose, they must be properly installed before they are used to lift the equipment rack. Eyenuts must be aligned to point towards the center lifting point of the cabinet (see Figure 4-5) and tightened to between 10-13.5 Nm (90-120 in-lbs) torque. This can be accomplished by hand tightening the eyenut and bolt assembly and tightening the bolt (turning clockwise) an additional 45 degrees. Correct eyenut tightness and alignment are crucial to ensure the eyenut assembly will perform to its intended lifting capacity.

Equipment Cabinet Installation

This section provides procedures for permanently mounting the EBTS equipment cabinets within a site. The Equipment Cabinet Installation section contains the procedures listed in the following table.

This section of the installation procedures covers the EBTS equipment cabinet. It does not refer to the Power Supply rack or battery rack. Refer to the manufacturer’s installation manual for information relating to these cabinets.

Cabinet Bracing Considerations

The EBTS equipment cabinet is self-supporting. In seismically active areas, additional bracing of the cabinet may be required to prevent it from tipping. However, the bracing hardware must be locally procured. There are no specific procedures within this manual for bracing cabinets in active seismic areas.

Always use appropriate lifting equipment and number of personnel whenever moving an EBTS equipment cabinet to reduce the risk of tipping. A fully configured EBTS equipment cabinet weighs approximately 276 kg (608 lbs). tipping can result in serious injury and extensive equipment damage.

EBTS Site Preparation and Hardware Installation

Access Considerations

Allow at least 0.8 m (2.6’) of floor space in front of and 15 cm (6”) behind the cabinets to permit access during installation. Although all maintenance, expansion, cabling, and antenna connections can be performed from the front or top, space is required behind the cabinets for proper air flow.

Figure 4-6 Typical EBTS Site Layout

Although 15 cm is recommended for space behind the cabinet, this is a minimum requirement. It is highly recommended that if possible around 60 cm be available to greatly ease the removal and replacement of FRUs.

Cabinet Position Considerations

The following procedures describe how to mount the equipment cabinet in an EBTS site facility. Be sure to read all of the procedures carefully.

The equipment cabinet must be secured to the floor for optimum stability.

6Configuration and Testing

Setup and Testing OverviewThe setup and testing procedures covered in this manual are intended to be used in conjunction with the information provided in Chapter 7, “EBTS System Troubleshooting” and Chapter 3, “EBTS Interface Commands”. Together, the troubleshooting solutions and testing procedures, provide the necessary information to isolate failures to a Field Replaceable Unit (FRU) or Replaceable Part. This helps to keep system down-time to a minimum by quickly returning the site to normal operation.

All suspected faulty FRUs should be shipped to a Motorola depot facility for servicing or repair.

MMI Commands

You must be familiar with Man-Machine Interface (MMI) commands and their usage prior to performing procedures in this chapter. Improperly applying MMI commands can result in equipment damage.

Chapter 3, “EBTS Interface Commands” serves as a tutorial and reference for using the software commands. If you are not totally familiar with using the commands, read Chapter 3, “EBTS Interface Commands” before proceeding.

Service technicians can communicate with the EBTS through the use of MMI commands and a service computer. MMI commands provide testing capabilities with access to alarm log files and various diagnostic tests. MMI commands also provide a means to configure the Site Controller and Base Radio(s) for intended operation, and to enable various system tests.

Two different command sets, Site Controller and Base Radio (BR), allow testing of the EBTS via the MMI.

A select number of MMI commands are used in the procedures within this chapter. The complete set of MMI commands, including both Site Controller and BR commands, are defined in Chapter 3, “EBTS Interface Commands”.

6866538D01-C 6 - 1February 2005

Configuration and Testing

Setup and Testing Procedures

The setup and test procedures in this manual are used to test the functionality of the EBTS and help isolate failures to the module level. If a failure cannot be isolated after performing these tests, refer to the tables in Chapter 11, “Backplane” for additional information.

The setup and testing procedures are divided into the following chapters:

• Site Controller Setup and Verification

• Equipment Cabinet Setup/Verification

• Conformance Testing

For Site Controller Indicators please refer to Table 8-2 on page 8-3.

Configuration and Testing

Service Terminal Setup

This procedure assumes power is applied to the EBTS system but the Site Controller has not yet been switched on. If power is not applied, perform the procedures in Chapter 4 - Final Checkout.

In the following procedures, whenever you are instructed to enter software commands they will be presented in bold lettering. Enter all commands exactly as they appear. The command prompt will precede the command, as in the following example.

Example: SC> help

Site Reference Check

Verify the GPS Receiver status as follows:

Perform this procedure only after Starting the Application Software. The service terminal must currently be displaying the SC> prompt in order to perform the following procedure.

1 At the SC> prompt, type: status sri

Verify that:

• the GPS Training State is “Closely Trained.”

• the Free Run state is “False.”

The GPS LED will flash satellite tracking commences and will be fully on once GPS is fully trained.

If satellite tracking is NOT ADEQUATE, make sure:

• the GPS receiver has been allowed enough time to locate the satellites (in extreme cases this may take up to 2 hours)

• the GPS antenna cable is properly connected. If it is not, reconnect the cable properly and then reset the Site Controller. If cable is found to be properly connected, the GPS antenna is possibly faulty.

Refer to Chapter 7, “EBTS System Troubleshooting” for more information on troubleshooting GPS

Do not attempt to make a resistance check of the GPS antenna. Damage to the active devices within the antenna element may result.

Redundant Site Controller Check

This procedure verifies that the any redundant TSC in an EBTS is correctly configured and should be able to take-over in the event of the active TSC failing.

In an EBTS with a redundant TSC either TSC A (upper TSC) or TSC B (lower TSC) may take the role of the active TSC at power-up.

Configuration Mode Checks

1 Verify using TESS that both TSC's are configured with the same TSC and BRC code and configuration files.

2 Verify using the MMI command 'id' that the uppermost TSC has identity 'A' and the lowermost TSC has identity 'B'. These identities are used in reporting faults to the CNE and to then ensure correct TSC identification. This command can also be used to configure the TSC identity if required.

3 Verify using the 'force_active' command on the standby TSC (TSC with active LED off) that the standby TSC can take control. The active LED should now illuminate. This check verifies operation of the TSC interlock mechanism and interlock cable.

6 - 8 6866538D01-CFebruary 2005

Configuration and Testing

This check should be performed with both TSC’s in configuration mode.

4 Repeat the previous process with the other Site Controller

Application Mode Checks

1 From the Application mode MMI use the command 'status peer'. This command will verify inter-TSC communication and provides a further check on the TSC configuration. The expected output of this command is as follows:

2 Switch-over to the standby TSC can be verified by switching off the active TSC or using the MMI reset command on the active TSC. This check should only be performed if loss of operational service is acceptable.

Redundant BR Checks

In Dimetra IP systems the TSC may be configured to control a redundant BR to either provide back-up Base Radio operation, in the event of a Base Radio failing, If configured this Base Radio can also be switched in by the CNE to provide extra capacity. This feature is configured by the EBTS Service Software (TESS). The redundant BR feature requires either an Auto Tune Cavity Combiner (ATCC) or a hybrid combiner to operate, as the standby BR must be able to configure itself to the radio frequency used by a failed BR. In systems with multiple ATCC's, minimum channel separation must not only be maintained between channels on each ATCC, but also between channels of all ATCC's. This allows the redundant BR to be able to replace any failed BR and allows the redundant BR's ATCC to maintain correct channel separation. Note that, only the last BR (highest position number) in the EBTS may be configured for redundant BR operation.

Verification Checks

Switch-over to the standby BR may be precipitated by turning off one of the active operational BRs.

This operation should only be performed if some loss of operational service is acceptable.

The status of each BR at the site may be obtained using one of the applications mode MMI command 'status sc -all' or 'status br', e.g. to determine if any BR has failed.

Note that, a failed BR will remain replaced by the standby BR until the either the ZM requests a reset of the standby BR position or the 'reset -br' MMI command is used to reset the standby BR position.

Selecting Base Radio Position and Receivers

During equipment cabinet setup, MMI is used to:

• Set the position of the Base Radios within the equipment cabinet.

• Select a particular Base Radio. This is required when assigning transmit and receive frequencies to a particular Base Radio.

• Select a receiver complement within a Base Radio.

These operations are described below. Refer to Chapter 3, “EBTS Interface Commands” for detailed information on using the MMI commands.

Setting and Accessing Base Radio Position

The set position command programs the position number where a Base Radio is mounted within a selected cabinet.

The set cabinet command programs the cabinet number where the Base Radio is mounted. For single cabinet EBTS, this is set to “1”. For multiple cabinet EBTS, the Base Radios in the first cabinet are set to “1”; the Base Radios in the second cabinet are set to “2”, etc.

Base Radio designation starts from the bottom of the cabinet, with the lowest Base Radio designated as “1”. For example, a cabinet with four Base Radios would have the lowest Base Radio being designated as “1”, and the highest being designated as “4”.

This command would also be used in accessing a particular Base Radio within the cabinet.

Configuration and Testing

Conformance TestingThis section describes a number of MMI commands essential to the operation of a Dimetra EBTS for ETSI Conformance testing and general field testing as well as troubleshooting. A short description of each command is given as well as two examples of how the commands are to be used. Other sections in this manual contain specific test procedures; this section is intended as a tutorial and to provide a background into MMI operation.

Site Controller Operation (RF Conformance Testing)

This section describes setting up the Site Controller to serve as a frequency reference to the Base Radio(s) for purposes of RF Conformance Testing. For purposes of RF Conformance Testing, the Site Controller host microprocessor will run a version of application software that will be configured to track and lock onto Global Positioning System (GPS) satellites. The Site Controller will discipline a 5 MHz frequency source to GPS, as well as recover a 1 Pulse-Per-Second (PPS) timing signal. The 5 MHz and 1 PPS signals are multiplexed onto a single coaxial cable and distributed to each BR of the EBTS.

The 5 MHz and 1 PPS signals are the frequency reference for all EBTS signal processing and system timing. If the Site Controller is not set up as described below, all RF transmissions and receptions will be as much as 2 kHz off frequency. Therefore, it is imperative to configure the Site Controller for proper GPS reception before any further RF tests are performed. The procedures described below assume that Site Controller Application Software has been properly loaded into the Site Controller.

The Site Controller has an MMI available through the front panel “Service Access” DB-9 connector using a null modem cable. A communications package such as Procomm or Smartcom is required to be running on the service computer. The BAUD rate is 19200. For the purposes of establishing proper GPS operation, no user actions within the Site Controller MMI are required to configure the Site Controller. The MMI “Service Access” connector is available for observing the GPS receiver activity, and observing that the receiver has acquired and locked onto the GPS satellites. The 5 MHz monitor port (“Mon”) on the Site Controller front panel is available for externally monitoring and measuring the 5 MHz frequency reference.

Perform the following steps to bring the Site Controller GPS on line:

1 Make certain GPS antenna(s) are properly connected and installed as described in Chapter 4, “EBTS Site Preparation and Hardware Installation”.

2 Have the service computer connected to the Site Controller MMI.

Make certain that the Site Controller is the first module to be powered-up. Base Radio(s) Power switches should be OFF at this point.

3 On the Site Controller, set the Power switch to ON.

4 Observe on the service computer that several self-tests are completed.

5 Execute the status sri command and observe that the GPS receiver is actively tracking several satellites.

6 - 26 6866538D01-CFebruary 2005

Configuration and Testing

Upon initial start-up of the GPS receiver, it may take as much as 25 minutes for the system to completely acquire and lock the Site Controller to GPS.

6 On the Site Controller, observe that the “GPS” green LED indicate that the Site Controller GPS receiver has successfully acquired and locked onto GPS.

7 When acquire/lock is verified, proceed to the “Base Radio MMI Access” procedure.

Base Radio MMI Access

The BR MMI is accessed using a service computer connected to the BRC front panel DB-9 connector (service port) via a null modem cable. A communications package such as Procomm or Smartcom is required to be running on the service computer. The Baud rate is 19200; frame is no parity, 8 bits, 1 stop bit.

Configuration Mode Access

Upon power up or reset, the BR will go through some memory tests and then prompt the user to press any key within 10 seconds to get into the test mode.

When prompted, pressing a key within 10 seconds must be done in order to perform the various tests described in this chapter.

1 Connect the RS-232 port on the service computer to the STATUS connector located on the front of BRC.

2 Apply power to the BR and observe the service computer for memory self-test indication.

3 When the BR requests any key to be pressed, press return.

The service computer display shown below appears during the 10-second period waiting for test mode entry.

After 10 seconds, the BR will display the following:

Configuration and Testing

If the 10-second period passes without pressing any key, the BR will display an indication that it is waiting for a download of application code. If this happens, press the Reset button on the BR to get back to the 10-second opportunity to go into test mode.

Upon entering the test mode, the BR will continue with some self-tests for several seconds and then display a password prompt, as shown below. Entering motorola as the password will result in the BRC> prompt being displayed, at which point Base Radio MMI commands can be executed.

Entering help at the prompt will list all available commands.

Transmit and Receive Frequency Setting

Commands

BR frequencies are configured with the set tx_freq nnn.nnnn and set rx_freq nnn.nnnn commands, where nnn.nnnn is the desired frequency in MHz. These frequency settings are stored in non-volatile memory.

Keying Base Radios and Setting Power Levels

Some commands executed during Conformance Testing will bypass normally available alarms and protection associated with normal EBTS operation.Therefore, it is imperative to adhere to all cautionary information and follow instructions exactly as written in the following procedure.

6 - 28 6866538D01-CFebruary 2005

Configuration and Testing

There are two MMI commands required to key a BR to a desired power level: set default_tx_power nn and key.

The key command sets the BR to use a default_tx_power parameter for its target power. This default level may be modified using the set default_tx_power nn command, where nn may range from 5 to 80Watts. This default power level is stored in non-volatile memory in the BRC until changed using the set default_tx_power command. The BR will come from the factory set for the highest available power (80 Watts).

Execution of the dekey command stops all RF transmissions and sets the tx_test_mode to stop.

Set default_tx_power nn bypasses all internal checks and alarms. The BR where the command is executed shall be connected to a dummy load and not an antenna.You must check and ensure that no existing alarm conditions exist prior to executing this command.

Two wattmeters are available in the Dimetra EBTS for diagnostics purposes. The first wattmeter is located within the PA at its output. It is accessed using the get fwd_pwr command. This command reports the measured power at the output of the PA. Generally, an output of 80 Watts is required at this point to achieve 25 Watts at the antenna port of the EBTS. The second wattmeter uses the power monitor located in the RFDS. It is accessed with the get wattmeter command. This wattmeter is only available on the bottom BR (number one) of the EBTS. The power levels reported with the get wattmeter command consist of the composite power from all keyed Base Radios in the EBTS; one keyed BR will report approximately 25 Watts, while four keyed radios will report approximately 100 Watts.The actual power level of the APM is the output power of the antenna plus 1 db power loss in the duplex filter.

Configuring Test Signal Types

The Dimetra BR is capable of transmitting and receiving several different types of test signals. Several MMI commands are available to configure the BR for these test signals. The first command, set tetra_format, configures the BR to transmit and receive signals per the ETS300-394 TETRA standard. The set tetra_format command is defined as:

set tetra_format MCC MNC CC downlink uplink trigger ms_pwr acc_prm

The set tetra_format variables and their definitions are listed in Table 6-8. Default settings are also listed.

Table 6-8 set tetra_format variables

Variable (Definition) Setting

MCC (mobile country code) default= 0

MNC (mobile network code) default= 0

CC (colour code) 1 to 63; default= 1(In the Anritsu 3660 generator, the two least significant bits should always be 1)Example:cc=1 => Anritsu cc = 7cc=3 => Anritsu cc = F

6866538D01-C 6 - 29February 2005

Configuration and Testing

Example:

set tetra_format 0 0 1 1 7 mframe

This command configures the BR to:

• scramble using a colour code of 1

• transmit a Type 1 TCH 7.2 downlink

• receive a Type 7 TCH 7.2 uplink

• put a multi-frame trigger on external trigger pin 9 of the service connector of the BRC

• set mobile power to 15 dBm

• set the access parameter to -53 dBm

Once the format has been set, the key command may be issued. When the transmitter has achieved the default power level the set tx_test_mode command may be issued to set the transmitter and receiver to T1 format. The T1 format configuration is set with the set tetra_format command. The set tx_test_mode command is defined as:set tx_test_mode <T1 stop exit>

downlink = 1 (TCH 7.2) (default; also used for reception ofchannel type 9 (STCH))

= 4 (TCH 2.4)= 31 (non-scrambled TCH 7.2 (Anritsu cc= 0))

uplink = 7 (TCH 7.2) (default)= 8 (SCH/F)= 10 (TCH 2.4)= 11 (SCH/HU+SCH/HU)= 31 (non-scrambled TCH 7.2 (Anritsu cc= 0))

trigger = off – no trigger (default)

= slot – triggers every slot

= mframe – triggers at start of frame 1 of each 18 frames.(This trigger is specifically designed for the Anritsu 3660 TETRA generator.)

= frame – triggers at start of frame 1 of each frame(actual timing includes a 64-symbol pretrigger)

mobile power = 001 15 dBm default (will default to 15 dBm if this field is omitted)

access parameter = 0000 -53 dBm default (will default to -53 dBm if this field is omitted)

Table 6-8 set tetra_format variables (continued)

Variable (Definition) Setting

6 - 30 6866538D01-CFebruary 2005

Configuration and Testing

The set tx_test_mode variables are listed below.

If the DC power to the station is cycled or a reset is executed, any setup using the tetra_format and tx_test_mode commands will be lost. These commands will then revert back to their default conditions.

Receiver Testing Methods

The BR will only properly receive a TETRA formatted signal if the tetra_format command has been set, the tx test mode has been set to T1, and the uplink signal that is to be received is correctly timed per ETS300-394. (The T1 mode does not require that the transmitter be keyed to test the receiver, although it may be keyed if desired.) Timing is required such that the uplink slot is received precisely 2 slots after the corresponding downlink slot has been transmitted.

Receiver testing is achieved in two ways, as follows:

• Once the BR is in T1 mode, the TETRA receiver is functioning per the ETS300-394 standard. Recovered data is available on the DB-9 RS-232 test connector located on the rear of the BR being tested. This data may be analysed for BER and MER performance using a ETSI-compliant TETRA test connector analyser.

• A second means which does not require ETSI-compliant analyser is available via the MMI. When a get rssi command is issued, recovered data will be analysed by the microprocessor within the BR. BER and MER will be reported to the service computer along with the receive signal level for each active diversity receiver. When the get rssi command is issued, the ETSI test connector activity is suspended until the get rssi action has completed its report.

Table 6-9 set tx_test_mode variables

Variable Setting

T1 (Tetra framed) Tetra FramedWhen set, places TX path from DSP to downlink. (If tetra_framed was not sent before tx_test_mode, station defaults to:

downlink= 1uplink= 7trigger= offcolour code= 1)

RX path to DSP defaults to uplink= Null

tetra_format needs only be sent once; the BRC will “remember” for all following tx_test_mode commands.

stop no samples to the Tranlin from the DSP

exit samples with zero amplitude to the Tranlin from the DSP

6866538D01-C 6 - 31February 2005

Configuration and Testing

The get rssi command is defined as follows:get rssi reports samples

When channel types 8 (SCH/F), 9 (STCH), and 10 (SCH/HU) are tested, MER is actually reported even though the get rssi command will return a display as “BER”.

Example Test Setups Using Commercially Available Generators

Test Setup for T1 Test Signal

The following procedure verifies receive hardware functionality and downlink/uplink using a generator configured to produce a TETRA uplink type 7 TCH7.2 signal with scrambling. The generator is configured as follows:

• country colour code/scrambling code= 1

• triggering= frame triggering

• delay= 128 bits (64 symbol BR pretrigger)

• output level= -85 dBm

In this example, the EBTS is a four-channel cavity combined system. BR #1 is already set for 940.0125 MHz TX frequency and 925.0125 MHz Rx frequency. Default power setting of 80W is used.

1 Terminate Junction Panel TX ANT port with a 250 W load.

2 Connect signal generator RF output to Junction Panel RX1 port.

3 Using a suitable test connector, make breakout leads for pin 9 of the DB-9 connector on the front panel of the BRC and ground. These will be connected to the Signal Generator trigger input.

4 Execute sys_gain and set to on.

5 Execute set tetra_format and set variables as follows:

set tetra_format 0 0 1 1 7 frame

This results in the BR transmitting a Type 1 TCH7.2 downlink with a scrambling code of 1 and uplink information on the control slot (Frame 18 slot 1) set for Type 7 TCH7.2 uplink with a colour code of 1. The BR receiver will be set to receive a Type 7 TCH7.2 uplink with a colour code of 1, and frame triggering will be output on pin 9 of the BRC DB-9 connector.

6 Key the BR using the key command.

Table 6-10 get rssi command

Variable Definition

reports reports = the desired number of reports that is to be displayed to the service computer. Range is 1 to 10000.

samples samples = the number of frames worth of data to be averaged into each report. One frame of data is 2040 bits. Range is 1 to 1000.

6 - 32 6866538D01-CFebruary 2005

Configuration and Testing

7 Observe the following:

8 Observe output of the BR using the get fwd_pwr command. The output should be approximately 80 W.

9 Observe approximately 25 Watts at the output of the EBTS with either the external wattmeter, the get wattmeter command, or a commercially available powermeter.

The set tx_test_mode T1 command changes both the transmitter and receiver over such that TETRA framed signals are being transmitted and the receiver is configured to process a TETRA uplink as defined with the set tetra_format command. The trigger is also functioning as set with the tetra_format command.

Assuming the signal generator trigger is timed properly, the recovered data will be appearing at the output of the ETSI-compliant test connector at the rear of the BR. Execution of get rssi 10 1 will result in BER being computed within the BRC and displayed on the service computer as follows:

Site Controller Fault Indications

The built-in system troubleshooting intelligence is mainly accessed through the Site Controller and Base Radio(s) LED and Man-Machine Interface (MMI) status and fault indications.

This chapter provides fault indications for the Site Controller which has been configured for use in a Dimetra IP system.

Some indications list several possible failures along with corresponding corrective actions. If a failure is isolated to the Site Controller, the suspected unit should be replaced with a new one. This restores the system to normal operation as quickly as possible.

Suspected Site Controllers should be shipped to the appropriate Motorola repair depot for repair.

Fault indications should be considered in the order shown in table below.

EBTS System Troubleshooting

Troubleshooting: General

This section details usage of the Application mode MMI command 'status sc' for general troubleshooting and to determine the site controller status. This command enhancement is only available on System Releases supporting the redundant TSC.

Use the 'status sc' command. Check the returned status and proceed as detailed in Table 7-2.

This section details usage of the Application mode MMI command status sc for general troubleshooting and to determine the site controller status.

This command enhancement is only available on System Releases supporting the redundant TSC.

Use the status sc command. Observe the “Overall Status” field of the resulting output and proceed as follows.

• If Overall Status = Initialising – waiting for TSC configuration file load, the configuration file may be corrupt or is not present. See “Troubleshooting: TSC Config File” on page 7-5.

• If Overall Status = Attempting to Activate – waiting for BRs, the TSC may be unable to communicate with the BRs. See “LED Fault Indications” on page 7-2.

• If Overall Status = Active – <state> / <reason>, this is an indication that the TSC is currently active, together with the site reference state and the reason for that state. These states and reasons are explained in Table 7-2 and Table 7-3.

UHSO_AGING The UHSO is approaching end of life and will need replacing soon.

SITE_REF_ALARM An unspecified site reference condition has occurred.

FREQ_CALIB_TIMER_EXPIRY The SR has been free running without GPS for over 350 days - GPS calibration is required to ensure RF frequency stability & compliance.

GPS_OK The GPS receiver is supplying a valid 1PPS timing source.

Table 7-3 Site Reference States

Site Reference State Explanation

UNKNOWN The site reference is initializing - this is a transient state that may persist for a few minutes at start up.

ENABLED_SYNC The site reference is fully trained to GPS - This is the highest level of functionality.

DISABLED The site reference is not working.

FREE_RUN_SYNC This is the first level of fallback - The site reference will continue to provide its highest level of service in this state until the free run timer expires.

EBTS System Troubleshooting

Troubleshooting: TSC Config File

The TSC will not boot or operate correctly and GPS will not start training unless a valid Configuration File is stored in its Flash Filing System. Use the method described in General Check of a TSC File to ensure that either tsc.cf.1 or tsc.cf.2 is selected as the current file, and is shown as valid.

Troubleshooting: BRC Config Files

The BRC will not boot or operate correctly unless a valid Configuration File is stored in the TSC’s Flash Filing System. Use the method described in General Check of a TSC File to ensure that the file shown in the following table is valid for the BR of interest.¯

Config files will only normally be present for installed BRCs.

Troubleshooting: BRC Code File

The BRC will not boot or operate correctly unless a valid Code File is stored in the TSC’s Flash Filing System. Use the method described in General Check of a TSC File to ensure that either brc.code.1 or brc.code.2 is selected as the current file, and is valid for the BR of interest.

NON_SYNC This is the second level fallback - The site reference is providing service however any feature that needs sites to be synchronized may be impaired.

NON_SYNC_ADJ_REQ The site has been operating in its 2nd level fallback mode for too long (> 350 days) and should be disabled by the operator.

ENABLED_NON_SYNC The site has been configured to operate in its 2nd level fallback mode (FNC) to enable start-up without GPS.

EBTS System Troubleshooting

Troubleshooting: General Check of a TSC File

To check the validity of a particular file in the TSC’s Flash Filing System it is necessary to use both the dir command and the attrib command as follows.

This example will look at the TSC’s configuration file, tsc.cf.

Using the dir command first ensures that the information shared between dir and attrib is synchronised.

1 Use the dir -all command to produce a listing of all files on the TSC. There is no wildcard option with dir. Check the files of interest do not have any warning after their details. This shows only a small part of the typical output.

reg.dat.bk1 0 - not set- 000000 00000000 (bad header)tsc.cf.1.bk1 11635 - not set- 000000 2dbb8018tsc.cf.2.bk1 0 - not set- 000000 00000000 (bad header)

In this example tsc.cf.1 looks like a valid file, whilst tsc.cf.2 has a bad header warning so it can’t be valid. The ‘.bk1’ indicates that the file is back-up copy 1.

2 Use command ‘attrib tsc.cf*’ to produce a listing of the TSC’s configuration files attributes.

SC: attrib tsc.cf*ATTRIB NAME VERSION DATE--------------------------------------------------------r- tsc.cf pr3swdl 20/02/2001_18:39:33cn--r- tsc.cf.1 pr3swdl 20/02/2001_18:39:33---w-a tsc.cf.2 - -SC

Note which file has the ‘c’ (Current) attribute and ensure that:

• It also has the ‘r’ (read) attribute. If the file has the w (write) attribute, it is not valid.

• Also check the generic file title (‘tsc.cf’ in this case) shares the same version and date information.

If there is no valid file then this should be downloaded to the TSC again, using either EBTS Service Software (TESS) or Software Download (SWDL.)

The following fields are of particular relevance during fault diagnosis:

GPS Training: The GPS Training status will be returned as ‘WAITING’ whilst searching for sufficient and adequate satellites. When satellites have been located the state will go to ‘LOCKING’. When the Site Reference has locked to GPS the status will be shown as ‘CLOSELY TRAINED’.

Free Run: This should be set to FALSE. A status of ‘TRUE’ indicates that the timing reference is free running.

Number of adequate satellites. In the example above there are seven satellites that have given full positional information (mode 8), as indicated by the ‘Strict Tracked SATS’ field.

Alarm Status: This should be OK.

The other fields in this display are primarily for Motorola engineering use.

If the status sri MMI command indicates that there are no satellites available. Then there may be a possible hardware fault. Refer to Section GPS Receiver Detailed Troubleshooting for further details.

6866538D01-C 7 - 7February 2005

EBTS System Troubleshooting

Troubleshooting: GPS Training and Site Reference Faults (Release D5.2 and later)

The timing subsystem within the EBTS consists of 2 major components:

• A GPS receiver and

• the Site Reference.

The status sri command and its sub commands provide the capability to diagnose GPS and Site Reference faults. An output similar to the one shown below will be obtained for a fully functional system:

The following fields are of particular relevance during fault diagnosis:

• Site Reference Operating OK

YES: This indicates that the site reference is providing timing services to the TSC.

NO: The site reference is not operating, therefore the EBTS will not be able to provide any service. Examining the state of items below will indicate the reason for this condition.

• Site Reference State

Site Reference State = START UP: The site controller is starting up and the site reference has not been fully initialized yet. The site reference and the EBTS will not be operational at this point. This is a normal transitory state.

Site Reference State = ACQUIRE FREQUENCY LOCK: The site reference is in the process of locking to the reference signal provided by the GPS receiver. This process may take several minutes. The EBTS will not be able to provide any service until this process completes.

Site Reference State = MAINTAIN PHASE LOCK: This is a normal operational mode of the site reference. The EBTS will be synchronized with any other EBTS that has attained this state, this means that type 1 handovers and any other feature that require sites to be fully synchronized will be available.

Site Reference State = SYNCHRONISED FREE RUN: This is a fallback state which indicates that the EBTS is not tracking sufficient GPS satellites to provide a timing reference to the site. The EBTS is capable of operating with no loss of performance for up to 12 hours. (Dependant on configuration). If this condition occurs frequently or persists, the health of the GPS system should be assessed. See GPS Tracking criteria and GPS Antenna evaluation in section 4 of this manual

EBTS System Troubleshooting

Site Reference State = UNSYNCHRONISED FREE RUN: This is a fallback state for an ASC configured EBTS and the normal operating state for FNC configured EBTS. When configured for ASC, the site will enter this state if adequate GPS tracking is not achieved before the configured GPS start up timer expires or after the expiry of free run timer if the site was previously synchronized. The site is capable of operating in this mode for up to 12 months. In this state the EBTS is capable of providing all services except those that require synchronization between adjacent sites, e.g. type 1 handovers.

Site Reference State = MAINTAIN FREQUENCY LOCK: If an adequate GPS signal becomes available whilst operating in UNSYNCHRONISED FREE RUN the EBTS will enter this state where the site reference calibration data will be updated, thus prolonging the amount of time where service can be maintained.

Site Reference State = DISABLED: The site reference has detected an error and is unable to provide any service. The EBTS will not be able to provide any service whilst the site reference is in this state. The cause of this state is dependant on the configured operating mode of the EBTS:

• NSC: The EBTS has been in the SYNCHRONISED FREE RUN state for longer than the configured free run time.

• FNC / ASC: The EBTS does not have any calibration data - The EBTS needs to be run initially with GPS before FNC operation without GPS is possible.

This condition may also be due to hardware failure within the site controller.

• Site Reference Configuration

Site Reference Configuration = ASC, NSC or FNC: This is the installation selected configuration of the site reference subsystem. See “Site Reference Operation Modes” on page 4-16 for details.

During start-up, the configuration will be reported as NSC regardless of the actual configured mode.

• Site Reference 1 PPS Input Status

Site Reference 1 PPS Input Status = OK or NOT OK: This indicates whether a valid signal is being received by the site reference system.

• GPS Operating OK

GPS Operating OK = YES or NO: This indicates whether the GPS receiver is tracking sufficient satellites to provide a timing reference input to the site reference. This parameter needs to be ‘YES’ for NSC operation and should be YES for ASC operation. Detailed information on the GPS receiver may be obtained from the status sri -t and status sri -gps commands. See the following section for details.

• GPS State

GPS State = NOT TRACKING: The GPS receiver is not tracking any satellites. This condition may persist for some minutes after start-up. Detailed information on the GPS receiver may be obtained from the status sri -t and status sri -gps commands. See the following section for details.

GPS State = POSITION HOLD: This is the normal operating state of the GPS receiver.

6866538D01-C 7 - 9February 2005

EBTS System Troubleshooting

GPS State = SITE SURVEY: The GPS receiver will operate in this state for several hours after a EBTS is started in a new location for the first time. The GPS receiver is attempting to determine accurate coordinates to enable operation in position hold.

• GPS Satellites Tracked

GPS Satellites Tracked = <0 .. 12>: This is the number of satellites tracked that are available for timing.

• Sync Free Run Available

Sync Free Run Available (Minutes): This is the number of minutes that the EBTS will operate without any degradation of service if the GPS receiver stops working and the site reference is configured for ASC or NSC operation. If the site reference is already in the free run state, the time shown will be the balance of free run time before the EBTS stops operating or switches to a lower level of service.

Unsync Free Run Available (Days Hours Mins): This shows the amount of time the sites 2nd level fallback (Unsynchronised free run) is capable of operating for. If the site reference is already in Unsynchronized free run the time shown will be the amount of time the EBTS is capable of operating for before calibration is required.

• Last Calibration Date Time

Last Calibration Date Time: The site reference will be periodically calibrated whenever an adequate GPS signal is available. The EBTS is capable of providing service for up to 12 months without GPS after each calibration. This parameter shows the date and time of the last calibration snapshot.

• Calibration Due Date Time

Calibration Due Date Time: This shows the date where the EBTS will need calibration if the GPS receiver was to fail at this time.

• GPS Time

• UTC Time

• Local Time

• UTC Time Mode

UTC Time Mode = Not Precise or Precise: When the timing for the site reference is being derived from the GPS receiver the UTC mode will be precise.

• Synchronised

Synchronised = YES or NO: This indicates whether this EBTS is capable of operating synchronously with any neighboring EBTS.

Check GPS self test status by using the command status sri -t as shown below.

• If any of the self test items display a status of ‘FAIL’ the GPS receiver is faulty and the Site Controller should be replaced.

• If the Antenna status field displays open or short circuit, check the integrity of the antenna cabling or replace the antenna.

GPS antenna must be connected before the site is powered up for this status to be returned correctly.

• If the site is being powered up in a new location for the first time, the Almanac Data and the Location data fields should display a status of Invalid. Use the site_location -reset and invalidate gps nvram commands to ensure that the Almanac and Location data are cleared. The Site Controller must then be reset for these commands to take effect.

• Check Antenna, cabling and surge arrestors.

• Check Antenna placement; refer to “GPS Antennas” on page 4-34.

• Evaluate GPS signal strengths using the GPS evaluation kit as described within chapter 3 of this document.

• The RAIM (Receiver Automatic Integrity Monitor) facility should be enabled to allow detection and correction of GPS errors. Refer to the EBTS service software manual (TESS) for details.

• If no other fault replace the Site Controller

Base Radio Troubleshooting

Troubleshooting Overview

This section serves as a guide to isolate Base Radio failures to the FRU level. It contains procedures for:

• Troubleshooting

• Verification/Station Operation

Recommended Test Equipment

Table 7-6 lists the recommended test equipment to perform the Base Radio troubleshooting/station operation procedures.

Troubleshooting Procedures

The Base Radio is computer-controlled and employs state-of-the-art digital signal processing techniques. Many of the troubleshooting and station operation procedures require Man-Machine Interface (MMI) commands. These commands are used to communicate station level commands to the Base Radio via the RS-232 communications port located on the front of the BRC.

The field maintenance philosophy for the Base Radio is to repair by replacement. The station is comprised of self-contained Field Replaceable Units (FRU). A defective FRU is replaced with a

EBTS System Troubleshooting

Selecting Base Radio Position and Receivers

When the Base Radio Controller (BRC) FRU is replaced, the BRC will need to be reassigned to the Base Radio location within the Equipment Cabinet. Also, reassignment of the receiver complement is required. These reassignments are accomplished through the service terminal hookup and Man-Machine Interface (MMI) described in Chapter 3 and Chapter 6.

In brief, MMI is used to:

• Set the cabinet (1 to 6) and the position of the Base Radios within the equipment cabinet.

• Select a particular Base Radio. This is required when assigning transmit and receive frequencies to a particular Base Radio.

• Select a receiver complement within a Base Radio

These operations are described below. Use Chapter 3, “EBTS Interface Commands” for detailed information on using the MMI commands.

Setting and Accessing Base Radio Position

The set position command programs the position number of where a Base Radio is mounted within a selected cabinet.

Base Radio designation starts from the bottom of the cabinet, with the lowest Base Radio designated as “1”. For example, a cabinet with four Base Radios would have the lowest Base Radio being designated as “1”, and the highest being designated as “4”.

This command would also be used in accessing a particular Base Radio within the cabinet. Accessing a particular Base Radio is required, for example, when assigning the transmit frequency to a Base Radio.

Selecting a Receiver Complement For a Base Radio

The set rx_fru_config command sets which receivers should be present in a selected Base Radio. The command has provision for all possible complements of three receivers.

The set rx_mode command selectively enables any combination of individual receivers within a selected Base Radio, while disabling any receiver that was not specifically selected.

Anti-Static Precaution

The Base Radio circuitry contains many CMOS and other static-sensitive devices. Take precautionary measures to prevent damage of Base Radio modules by static discharge when servicing the equipment.

Observe the following additional precautions:

• Wear a wrist strap (Motorola Part No. 4280385A59 or equivalent) at all times when servicing the Base Radio to minimise static build-up.

• A grounding clip is provided with each EBTS cabinet. If not available, use another appropriate grounding point.

• DO NOT insert or remove modules with power applied to the Base Radio. ALWAYS turn the power OFF with the Power Supply breaker switch. This switch is located on the front panel of the module.

• Keep spare modules in factory packaging for transporting. When shipping modules, always pack in original packaging.

6866538D01-C 7 - 17February 2005

EBTS System Troubleshooting

Replacement Procedure

Perform the following steps to remove any of the FRUs from the Base Radio chassis:

1 Remove power from the Base Radio by setting the Power Supply ON/OFF switch to the OFF position. This switch is located behind the front panel of the Power Supply.

2 Remove the TORX screws securing the faulty module to the chassis; these are located on each side of the faulty module. Save screws for reuse.

3 Pull out the module.

4 Insert the non-defective replacement module by aligning the module side rails with the appropriate rail guides inside the Base Radio chassis.

5 Gently push the replacement module completely into the Base Radio chassis assembly using the module handle(s).

DO NOT slam or force the module into the chassis assembly. This will damage the connectors or backplane.

6 Secure the replacement module using two TORX screws removed during module removal. Tighten the screws to a torque of 0.65 Nm (5 in-lbs).

7 Apply power to the Base Radio by setting the Power Supply breaker switch to the ON position.

8 Proceed to Station Verification Procedures.

Base Radio Replacement

Perform Base Radio (BR) replacement as described in the following paragraphs.

The BR removal and installation procedures are included for reference. Field maintenance of BRs typically consists of replacement of FRUs within the BR.

Removal

Remove BR from Equipment Cabinet as follows:

1 Remove power from the Base Radio by setting the Power Supply ON/OFF switch to the OFF position reached through the front panel grill.

2 Set the appropriate breaker switch on the Breaker Panel to OFF.

3 Tag and disconnect the cabling from the BR rear panel connectors (Disconnect ground cable last).

4 Remove the four M6 TORX screws which secure the BR front panel to the Equipment Cabinet mounting rails.

BR weight exceeds 27 kg (60 lbs). First remove the PA and PSU (and any other modules as necessary) then lift out the BR from the cabinet, make certain BR is fully supported when br is free from mounting rails.

Two persons are required to replace a Base Radio. Alternatively, if only one person is available, the heavy base radio modules (Power Amplifier and Power Supply) shall be removed first and later the chassis can be removed easily.

5 While supporting the BR, carefully remove the BR from the Equipment Cabinet by sliding the BR from the front of cabinet.

Installation

Install BR in Equipment Cabinet as follows:

1 If adding a BR, install side rails in the appropriate BR mounting position in the rack.

BR weight exceeds 27 kg (60 lbs). Remove PA and PSU (and any other modules as necessary) before lifting the BR into the equipment cabinet. make certain BR is fully supported until br is fully placed in mounting position.

Two persons are required to replace a Base Radio. Alternatively, if only one person is available, the heavy base radio modules (Power Amplifier and Power Supply) shall be removed first and later the chassis can be removed easily.

2 While supporting the BR, carefully lift and slide the BR in the Equipment Cabinet mounting position.

3 Secure the BR to the Equipment Cabinet mounting rails using four M6 TORX screws. Tighten the screws to 4.5 Nm (40 in-lb).

4 Connect the cabling to the BR rear panel connectors as tagged during the BR removal. If adding a BR, perform the required cabling in accordance with the cabling diagrams (Attach ground cable first).

5 Perform BR activation as follows:

• If the BR is replacing an existing BR, perform the BR verification in accordance with Station Verification Procedures.

Station Verification Procedures

Station Verification Procedures cover methods to verify transmit and receive operations after a module has been replaced. Each section contains the equipment set-up and the procedure.

Replacement FRUs Verification

All module specific information is programmed in the factory prior to shipment. Base Radio specific parameters (e.g., receive and transmit frequencies) is down loaded to the Base Radio from the network/site controller.

Replacement FRU alignment is not required for the Base Radio. However, after a module is replaced, station operation should be verified.

FRU Replacement Procedures

Available FRUs

See Appendix C.

Site Controller Replacement

Perform Site Controller replacement as described in the following paragraphs.

Removal

Remove the Site Controller from the Equipment Cabinet as follows:

• Remove power from the Site Controller by setting the Power Supply ON/ OFF switch to OFF.

• Set CTRL A and CTRL B breaker switches (as applicable) to OFF.

• Tag and disconnect the cabling from the Site Controller rear panel connectors.

• Remove the four M6 TORX screws which secure the Site Controller front panel to the Equipment Cabinet mounting rails.

• While supporting the Site Controller, remove the Site Controller from the Equipment Cabinet by sliding the Site Controller from front of the cabinet.

Installation

Install Site Controller in Equipment Cabinet as follows:

• If adding a Site Controller, install side rails in the appropriate Site Controller mounting position in the rack.

• Connect the green/yellow ground conductor between the secondary ground bar and the grounding lug on the rear of the housing, and ensure the connection is tight.

• While supporting the Site Controller, slide the Site Controller in the Equipment Cabinet mounting position.

• Secure the Site Controller to the Equipment Cabinet mounting rails using the four M6 TORX screws. Tighten the screws to 4.5 nm (40 in-lb).

• Attach the Site Controller grounding cable. (Attach grounding cable before other cables.)

• Connect cabling to the Site Controller rear panel connectors as tagged during the Site Controller removal. If adding a Site Controller, perform required cabling in accordance with Cabling Diagrams in Chapter 5.

• Perform the Site Controller verification in accordance with Chapter 6, “Configuration and Testing”.

TETRA Site Controller (TSC)

Redundant Site Controller Removal/Installation

When installing a redundant TSC ensure that the configuration of both TSC’s is the same. This can be achieved by uploading the configuration via TESS of the active TSC and then downloading this configuration via TESS to the redudant TSC.

For service to be unaffected, the standby Site Controller must be powered down prior to disconnecting the unit. If the Interlock and LAN cables are removed when the Standby unit is powered-up, the SR output on the standby will start transmitting and conflict with the SR from the Active. This will cause the EBTS to go off-air. When reconnecting the unit, all connections must be replaced before the unit is powered up.

Lithium Battery Caution

This TSC contains a lithium battery.

Danger of explosion if the TSC battery is replaced incorrectly. Replace battery only with the same or equivalent type recommended by manufacturer. Dispose of used batteries according to the manufacturer’s instructions.

TSC Battery Removal/Installation

1 Examine the contents of the flash filling system using the Configuration Mode command attrib. Record the file attributes for each of the files.

2 Remove the Site Controller from the Equipment Cabinet. See “Removal” on page 8-8..

3 Remove the Site Controller cover by using a screwdriver.

4 Carefully remove the battery by hand or using two small screwdrivers.

5Insert the new Lithium battery (Motorola P/N M48T35AV) on TSC board as shown in Figure 8-6. Match the dot on battery with arrow on the PCB.

6 Close the Site Controller.

7 Install Site Controller in the Equipment Cabinet. See “Installation” on page 8-8.

8 Boot up into the Configuration Mode and clear the NV RAM contents using .resetnvr -all.

9 Then restore file attributes in the flash filling system using the attrib command again.

9Environmental Alarm System (EAS)

Environmental Alarm System (EAS)The EAS provides an electrical interface for alarm signals form the EBTS and site. The EAS provides input/output lines to connect to alarms to monitor such environmental conditions as site power, smoke detectors, and intrusion (burglar) detectors. Only one EAS is used per site. The EAS also receives alarms from the Breaker Panel and the RFDS. Base Radio alarms are sent directly to the Site Controller over the Ethernet LAN.

The EAS accepts 48 alarm inputs and provides eight control outputs. The inputs are opto-isolated and sense an opening of the contact between the alarm sensor and its return (i.e. the contacts are normally closed and activate the alarm when they open). Four RJ-45 connectors are used for the alarm connections within the Equipment Cabinet. The remaining alarm inputs and control (relay) outputs are accessible via two 50-pin connectors, only one of which is connected to the Junction Panel. The eight alarm outputs may be configured to respond automatically to certain EBTS state changes or to be manually controlled.

The eight alarm outputs are not supported with System Releases prior to D5.2 and on MBTS platforms.

Alarm wiring is connected to the EAS via the junction panel at the top of the EBTS. Some of the connections are dedicated to specific equipment, although several inputs are available for assignment by the customer. The EAS interfaces with the Site Controller(s) via an IEEE 1284 interface.

Figure 9-1 show the front view of the EAS.

Environmental Alarm System (EAS)

Theory of Operation

The EAS provides a direct interface between the Site Controller and various site alarms. Figure 9-2 shows a functional block diagram of the EAS.

The EAS is configured for 48 dry contact input sensors and 8 relay closure outputs. Each I/O module provides 4000 V of isolation between field wiring and sensitive control circuitry.

The Site Controller and EAS interact in a master/slave relationship. The Site Controller sends commands to the EAS to determine the status of alarm inputs or set the state of control outputs. The EAS, in turn, sends alarm status responses to the Site Controller.

The EAS continuously scans the status of the alarm inputs, ensuring that all alarms are consistently monitored.

Environmental Alarm System (EAS)

EAS Output Relay OperationThe EAS output relays can be used to provide automatic or manual control of external equipment that is connected to them. Each of the outputs can be independently configured to perform one of the functions listed in Table 9-3. The function assigned to each output is configured using the BTS Service Software and stored in the Site Controller’s configuration file. Any change requires a new configuration file to be downloaded and the Site Controller to be reset before it will take effect.

Each of the output relays has either normally open contacts, or both normally open and normally closed contacts (see later in this section). The term activated is used below to mean that the relay is not in its powered off position – i.e. in an activated relay, normally open contacts are closed, and normally closed contacts are open.

To determine the reason why an output has activated or deactivated, the following interface commands will be useful.

The eas_out command, with the output number given as an argument (e.g. eas_out 2 for output number 2), displays details of the most recent event that caused the output to activate or deactivate. For automatically controlled outputs, this information will describe a subsystem state change. For manually controlled outputs, a manual control operation will be described. In both cases, the date and time of the event are shown.

The status bts interface command displays the state and associated severity of all relevant subsystems. For more detail, including the date and time at which each subsystem last changed state, use status bts –l. If a particular subsystem is missing from the displayed list, this means that state information has not been received from that subsystem since Site Controller power up or reset.

Table 9-3 EAS Output Functions

Function Description

Output Not Used The output will not activate under any circumstances. This is the default behaviour.

Manual The output can be controlled manually using the eas_out interface command. For example, eas_out 1 on will activate output relay 1.

Not Wide Trunking The output will automatically activate whenever the site is not in Wide Trunking, and will be deactivated during Wide Trunking.

Warning or Higher The output will automatically activate when any one or more of the following EBTS subsystems is in a state with severity of at least warning: EBTS, Site Controller, Site Reference, EAS, Base Radio (including FRUs: BRC, Receiver, PSU, Power Amplifier, Exciter).

The status bts interface command allows the state of these subsystems to be queried.

Minor or Higher As above, but activated on severity of at least Minor.

Major or Higher As above, but activated on severity of at least Major.

Critical As above, but activated on severity of Critical.

Output Not Used The output will not activate under any circumstances. This is the default behaviour.

9 - 4 6866538D01-CFebruary 2005

Environmental Alarm System (EAS)

The following points must be considered when connecting external equipment to the outputs:

• Outputs configured for Not Wide Trunking, as well as for any of the severity based functions (e.g. Warning or Higher) will be active following Site Controller power up or reset. This is because the EBTS will initially be in the “No Trunking” state, which has a severity of Critical.

• The Base Radio state “Standby” has severity Minor. Therefore, outputs configured for Warning or Higher / Minor or Higher operation will always be active in an EBTS with a Standby Base Radio. (Not for EBTS PR 3.1)

Transmitter to Antenna Specifications

Table 10-2 lists the cavity combining RFDS transmitter port-to-antenna port specifications.

Analog Power Monitor (APM)

The APM measures the power readings and converts them into proportional DC voltages. For example, 320 Watts would be 5 V out (forward voltage) and 160 Watts would be 2.5 V out. This assumes antenna VSWR 1:1 (50 Ω). These voltages are then sent to the appropriate Base Radio where they are used to determine the forward and reflected power readings. They are also used to generate a VSWR alarm in the case of antenna feed problems.

RF Distribution System (RFDS)

Theory of Operation of Auto Tune Cavity Combiner (ATCC)

Figure 10-2 shows the block diagram of the auto tune cavity combiner.

A minimum of 2 watts is needed at a cavity input. The ATCC will automatically tune in 40 seconds maximum. For more detail, refer to the ATCC specification.

Once an RF signal greater than 2 watts is detected, the ATCC tunes the cavity and continuously keeps it tuned over humidity, temperature and changing transmit frequency, so long as it does not sense one of the following alarm conditions:

• Channel Spacing alarm

• VSWR alarm

• Failure to Tune alarm

Being tuned means that a cavity is within the insertion loss specification at the frequency of the applied PI/4DQPSK signal that is within the average input power range specified above. Being tuned also means that the cavity peak response is no greater than 25 kHz away from the TX carrier centre frequency. If the TX carrier does not change channel or average power level, the auto tune algorithm will not initiate a re-tuning on its own which exceeds +/- 300 kHz from the carrier frequency. The only exception occurs when the fine tune timer event happens. The fine tune timer is used to compensate for large variations in humidity and is default set to 480 Minutes. The cavity combiner is temperature compensated but large variations in humidity can de-tune the cavities up to 150kHz with the result of an increasing insertion loss.

When the fine tune timer event occurs all cavities with RF applied will be re-tuned for maximum output power of each TX carrier. The Fine tune timer can be adjusted to compensate for fast humidity variations for instance if the EBTS is installed in out door sites without air-conditioning. The recommended setting of the Fine tune Timer, if the EBTS is installed in a controlled environment is 480 Minutes. For sites where the EBTS is exposed to more than +/- 20% variation in RH then the recommended setting of the Fine tune timer is 60-200 minutes depending on the speed of the variation.

The BRC MMI command for setting the fine tune timer is explained in Chapter 3, “EBTS Interface Commands”. Having a second cavity tune up and pass through the desired channel, the desired channel’s insertion loss dips no more than 3 dB more than the max insertion spec for a period of 0.25 seconds. The cavity tuning rate should be faster than 1 MHz per second.

If any of the three alarm conditions are activated per channel, that channel’s relay will be energized in the normally open position. That channel’s Base Radio (BR) will need to have the fault condition be a logic high (for alarm condition).

Where the ATCC does not initiate an alarm condition, but a BR senses one, then the alarm harness connected to that BR is not making connection or is opened.

The following list contains control and monitoring features available via the RS-232 port:

• Request current tuned position/frequency of a specific cavity.

• Fine tune time feature, to re-tune each cavity with a specified interval.

• Park an individual cavity, but if RF power is still present, cavity will park and then retune again.

• Input power: request current measured input reflected power of a specific cavity.

• VSWR: request input VSWR of an individual cavity.

• Tuning status of each cavity; parked, tuning, tuned, and parking.

• Alarm conditions of each cavity shall be reported when requested, to include: VSWR, sub-band, channel spacing and failure to tune.

The Man Machine Interface (MMI) are Motorola’s commands to control the ATCC. Chapter 3 describes the MMI commands which are used on the Base Radio Controller (BRC) by using a terminal with its serial RS-232 cable connected to the RS-232 port on the front of the BRC. Before using ATC commands, type “set rear_serial autotune” to set up the BRC’s RS-232 port on the backplane.

RF Distribution System (RFDS)

Receiver MulticouplersFigure 10-6 shows a block diagram of the receiver multicouplers. Distribution of diversity receive antenna signals are distributed to the diversity receivers in the BRs using receiver multicouplers (RMCs).

RMC Operation and Receive Signal Flow

Each receive branch of the prime RMC uses a Low Noise Amplifier (LNA) and a Splitter that converts a single receive signal into multiple buffered receive signals. The Rx branches function identically.

The LNA takes the RX out signal from the Junction Panel. The RMC then provides four outputs and an expansion output. Each output is fed to a single receiver in the prime rack Base Radios (BRs). Up to four prime rack BRs are supported. The expansion output can be used to feed an expansion rack RMC with 4 BRs giving a total of 8 BRs per antenna. Outputs not used are to be terminated using a 50 Ω termination.

The RMC uses two Power Supply boards (power supply A and power supply B) in a dual-redundant arrangement. The Power Supply boards are located in the RMC tray. The power supplies converts the -48 VDC (hot) site power to +12 VDC and +24 VDC. The +12 VDC is used for the RMC LNAs and the Power Monitor. The +24 VDC is used to support the Power Monitor module.

Each power supply board is equipped with green and red LED indicators that indicate when the board is receiving power and functioning properly. The RFS1 and RFS2 circuit breakers on the cabinet breaker panel control the application of -48 VDC power to the A and B Power Supply boards.

Table 10-3 lists the RMC antenna port-to-receiver port specifications for a single receive branch.

RMC Alarm Output

Each RMC provides two alarm relay contact closure pairs that send alarm conditions to the Environmental Alarm System (EAS) in the event of RMC power supply or LNA failure. Under normal operating conditions (no alarm conditions present), the alarm outputs for both of these alarms are closed. Upon detection of an alarm condition, the respective alarm output will open. Via the cabinet alarm wiring harness, the alarm signals are routed from the Telco connector on the RMC to the RF#1 connector on the EAS.

Analog Power Monitor (APM)

The analog power monitor is a directional coupler that measures forward and reverse power and translates that into DC voltages. The DC voltages from the analog power monitor are connected to the Base Radio, which measures the two DC voltages and uses them to report forward and reverse power and the SWR (standing wave ratio). The SWR is calculated by the BR based on the two DC voltages.

10 - 20 6866538D01-CFebruary 2005

RF Distribution System (RFDS)

The purpose of the APM is to monitor the health of the antenna system. It is not an accurate absolute power measurement. The APM has been placed in the TX path as a compromise between measurement accuracy and minimization of potential problems caused by a natural phenomenon known as passive intermodulation. Passive Intermodulation occurs when two transmitter signals are mixed in non-ideal metal-to-metal joints such as connectors and is particularly critical in duplexed systems with many carriers.

The Analog Power Monitor is power supplied from the RMC (Receiver Multi Coupler).

Base Radio

Theory of Operation

The Base Radio operates in conjunction with a Site Controller via a properly terminated 10base2 Ethernet link. The following description assumes such a configuration. Figure 11-2 shows an overall block diagram of the Base Radio.Power is applied to the DC Power inputs located on the Base Radio backplane.

Power is applied to the Base Radio by setting the Power Supply power switch to the on position. Upon power-up, the Base Radio performs self-diagnostic tests to ensure the integrity of the unit. These tests are primarily confined to the BRC and include memory and Ethernet verification routines.

After the self-diagnostic tests are complete, the Base Radio reports any alarm conditions present on any of its modules. All alarms are reported to the site controller via the Ethernet LAN. Alarm conditions may also be verified locally through the STATUS port located on the front of the BRC and the use of a service computer.

The software resident in FLASH on the BRC registers the Base Radio with the site controller via the Ethernet LAN. Once registered, the Base Radio software is downloaded via the Ethernet LAN and is executed from SDRAM. Operating parameters for the Base Radio are included in this download. This software allows the Base Radio to perform call processing functions.

The Base Radio operates in a TDMA (Time Division Multiple Access) mode. This mode, combined with voice compression techniques, provides an increased channel capacity ratio of as much as 4 to 1. Both the receive and transmit signals of the Base Radio are divided into 4 individual time slots. Each receive slot has a corresponding transmit slot; this pair of slots comprises a logical RF channel.

The Base Radio uses diversity reception for increased talkback coverage area and improved quality. The Base Radio contains a triple receiver module in which all three diversity receivers are packaged in a single-slot module. Two Receivers are used with two-branch diversity sites, and three Receivers are used with three-branch diversity sites.

All Receivers within a given Base Radio are programmed to the same receive frequency. The signals from each receiver are fed to the BRC where a diversity combining algorithm is performed on the signals. The resultant signal is processed for error correction and then sent to the site controller via the Ethernet LAN with the appropriate control information regarding its destination.

The transmit section of the Base Radio is comprised of two separate FRUs, the Exciter and Power Amplifier (PA). The Exciter processes the information to transmit from the BRC in the proper modulation format. This low level signal is sent to the PA where it is amplified to the desired output power level. The PA is a continuous-keyed linear amplifier. A power control routine monitors the output power of the Base Radio and adjusts it as necessary to maintain the proper output level.

Base Radio Controller

BRC Overview

The Base Radio Controller (BRC) serves as the main controller for the Base Radio. The BRC provides signal processing and operational control for other Base Radio modules. Figure 11-3 shows a top view of the BRC with the cover removed. The BRC module consists of two printed circuit boards (BRC board and LED/display board), a slide-in housing, and associated hardware.

The operating software and codeplug are contained within the BRC memory. The software defines operating parameters for the BR, such as output power and operating frequency.

The BRC interconnects to the Base Radio backplane using one 96-pin DIN connector and one blindmate RF connector. The BRC is secured in the Base Radio chassis using two TORX screws.

Base Radio

Theory of Operation

Table 11-7 briefly describes the BRC circuitry. Figure 11-6 is a functional block diagram of the BRC.

Host Microprocessor

The host microprocessor serves as the main controller for the BR. It operates at a clock speed of 50.0 MHz, which is derived from the 25.0 MHz clock oscillator. The processor controls the operation of the Base Radio as determined by the station software contained in non-volatile memory. The station software is contained in a FLASH SIMM.

Serial Communication Buses

The microprocessor provides two general-purpose serial communications buses (SCC2 and SMC2).

The SMC2 serial communications bus is an asynchronous RS-232 interface. A 9-pin D-type connector on the BRC front panel provides a port for service personnel to connect a service computer. Service personnel can perform programming and maintenance tasks via Man Machine Interface (MMI) commands. The interface between the SMC2 port and the front panel Service Access connector is via EIA-232 Bus Receivers/Drivers. Table 11-6, “Service Access Connector Details,” on page 11-9 lists the DB-9 female connector pinout details on the BRC front panel.

Table 11-7 BR Controller Circuitry

Remote Station Shutdown Provides software control to cycle power on the BR

11 - 10 6866538D01-CFebruary 2005

Base Radio

The SCC2 serial communications bus is an RS-232 interface with synchronous or asynchronous capabilities. It can interface remotely to a synchronous modem. The SCC2 port connects via EIA-232 Bus Receivers/Drivers to RS232 connector located on the backplane of the BR. Refer to Table 11-21, “Backplane RS-232 Pin Dsub (P8),” on page 11-42. This port supports ETSI 300-394 requirements for a test connector which can be accessed for Rx data recovery during conformance testing.

Address and Data Bus

The microprocessor is equipped with a 32-line address bus used to access the non-volatile memory, SDRAM memory, and provide control via memory mapping for other circuitry in the BRC.

A 32-line data bus transfers data to/from the BRC memory, as well as other BRC circuitry. This data bus is buffered for transfers to and from the non-volatile memory. The data is not buffered for the SDRAM memory.

Non-Volatile Memory

The Base Radio software resides in an 8 Mb FLASH SIMM (expandable to 16 Mb) accessed by the Host Microprocessor via the 23 lines of the 32-line host address bus and the 32-line host data bus.

The data determining the station personality resides in a 32K x 8 codeplug EEPROM. The EEPROM is accessed by the microprocessor via 15 lines of the 23-line host address bus and the 8-line data bus.

Field programming information is downloaded from the network/Site Controllers. This data includes operating frequencies and output power level. Many of the station parameters may be adjusted but will not be stored within the station. Refer to Chapter 3, “Site Controller Commands” for additional information.

Volatile Memory

Each BRC contains 32Mb of SDRAM. The BRC downloads the station software code into SDRAM for the station to use. Data is lost upon loss of power or reset since the SDRAM is volatile memory.

The SDRAM also provides short-term storage for data generated and required during normal operation. Read and write operations are performed via the Host Address and Data buses. SDRAM memory locations are sequentially refreshed by the address bus and CS, RAS, and CAS signals from the Host Processor during normal operation.

Ethernet Interface

The Ethernet Interface is provided by SCCI of the MPC860 (Host Processor). It implements the CS/CDMA access method which supports the Ethernet 10Base2 standard.

The Ethernet Serial Interface performs the following major functions:

• 10 MHz transmit clock generation (obtained by dividing the 20 MHz signal provided by on board crystal)

• Manchester encoding/decoding of frames

6866538D01-C 11 - 11February 2005

Base Radio

• electrical interface to the Ethernet transceiver

An isolation transformer provides high voltage protection and isolates the Ethernet Serial Interface (ESI) and the transceiver. The pulse transformer has the following characteristics:

• Minimum inductance of 75 µH

• 2000 V isolation between primary and secondary windings

• 1:1 Pulse Transformer

The Coaxial Transceiver Interface (CTI) is a coaxial cable line driver/receiver for the Ethernet. CTI provides a 10Base2 connection via a coaxial connector on the board. This device minimises the number of external components necessary for Ethernet operations.

A DC/DC converter provides a constant voltage of -9 VDC for the CTI from a 5 VDC source.

The CTI performs the following functions:

• Receives and transmits data to the Ethernet coaxial connection

• Reports any collision detected on the coaxial

• Disables the transmitter when packets are longer than the legal length (Jabber Timer)

Digital Signal Processor

The Digital Signal Processor (DSP) and related circuitry process the station transmit and receive compressed audio/data signals. This circuitry includes the DSP, the TDMA Infrastructure Support IC (TISIC2), and the TISIC2 Interface Circuitry.

The DSP receives a 25 MHz clock, which it frequency multiplies by 4 to operate at 100 MHz. The DSP communicates with the Host Microprocessor via an 8 bit data bus. Communication with the Host Microprocessor is interrupt driven. The DSP also contains internal SRAM to store its programs and signal processing algorithms.

The inputs are digitised signals from the Receivers. The digitised samples are first received by TISIC2, stored in registers, and then read by the DSP via the DSP data bus.

The outputs are digitised voice audio/data (modulation signals) that are first sent to TISIC2 via a synchronous serial interface (SSI). TISIC2 reformats and reclocks the data and sends it to the Exciter module.

11 - 12 6866538D01-CFebruary 2005

Base Radio

TISIC2

The TISIC2 controls all internal DSP operations. This ASIC provides a number of functions, including the following:

• Interfaces with the DSP via the DSP (Port A) address and data buses.

• Accepts a 16.8 MHz signal and a 1 PPS signal from Station Reference Circuitry.

• Outputs a 2.4 MHz reference signal used by the Exciter and Receivers.

• Outputs a 4.8 MHz reference signal used by the Exciter to clock data into the LNODCT IC.

• Accepts differential data from Receivers (RX1 through RX3) via interface circuitry.

• Sends serial data to the Receivers (RX1 through RX3) via SBI data lines.

• Accepts and formats serial data from the DSP for transmission to the Exciter via interface circuitry.

• Generates 14.167 ms and 7.083 ms ticks. These are synchronised to the 1 PPS time mark from the Site Controller (TSC) for routing to the DSP.

Station Reference Circuitry

The Station Reference Circuitry is a phase-locked loop consisting of a high-stability Voltage Controlled Crystal Oscillator (VCXO) and a Phase Locked Loop IC. The OUT 1 or OUT 2 output from the Site Controller is connected to the 5 MHz/1 PPS A BNC connector on the EBTS junction panel. In this mode, the PLL compares the reference frequency to the 16.8 MHz VCXO output and generates a DC correction voltage. The control voltage enable switch is closed. This allows the control voltage from the PLL to adjust the high-stability VCXO frequency to a stability equivalent to that of the external 5 MHz frequency reference.

The VCXO is continually frequency-controlled by the control voltage from the PLL and outputs a 16.8 MHz clock signal which is applied to TISIC2.

TISIC2 divides the 16.8 MHz signal by 8 and outputs a 2.1 MHz signal. This signal is separated and buffered by a splitter. The output signal is then sent to the Exciter and Receivers as a 2.1 MHz reference via the backplane.

The 4.8 MHz reference signal generated by TISIC2 is applied to the Exciter module, where it is used to clock data into the TX PLA (Programmable Logic Array) IC.

Input Port

One general purpose, 24-line input port provides for various input signals from the BRC and station circuitry. These inputs are sent to the Host Microprocessor.

Input Port P0 In consists of 24 lines from circuitry in the BRC, as well as other modules in the station via the backplane.

Input Port P1 In consists of 24 lines of data written to Output Port P0 Out.

6866538D01-C 11 - 13February 2005

Base Radio

Output Port

One general purpose 24-line output port provides various control signals from the Host Microprocessor to the BRC and station circuitry via the backplane. The output port, Port P0 Out, consists of 24 lines from the Host Data Bus via latches.

Typical control signals from these output ports vary from the control signals for the eight front panel LEDs and the address select lines for SPI peripherals.

Remote Station Shutdown

The BRC contains circuitry to send a shutdown pulse to the Base Radio Power Supply. After receiving this pulse, the power supply cycles the power for the BR, including the 5.1 VDC, 28.6 VDC and 14.2 VDC distributed through the BR. The BRC generates the shutdown pulse through software control. A remote site uses the shutdown function to perform a hard reset of all modules in the BR.

Exciter

Exciter Overview

The Exciter, in conjunction with the Power Amplifier (PA), provides the transmitter functions for the Base Radio. The Exciter module consists of a printed circuit board, a slide-in housing, and associated hardware.

The Exciter interconnects to the Base Radio backplane using a 96-pin DIN connector and two blindmate RF connectors. Two TORX screws secure the Exciter to the chassis.

There are no controls or indicators on the Exciter. Specifications of the transmitter circuitry, including the Exciter and PAs, are provided in Base Radio section of the manual.

Figure 11-7 shows the Exciter with the cover removed.

Figure 11-7 Exciter (with cover removed)

6866538D01-C 11 - 17February 2005

Base Radio

Theory of Operation

Table 11-7 lists and describes the basic circuitry of the Exciter. Figure 11-8 shows the functional block diagram of the Exciter.

DAC and Alias filter

DAC and alias filter are used to convert digital baseband signal to analog baseband signal to meet the input data format for the LNODCT ICs.

Table 11-8 Exciter Circuitry

Circuit Description

LNODCT1 IC • Up converts the baseband data to the Transmit frequency• Down converts the Transmit frequency feedback signal to baseband• Uses a baseband Cartesian feedback loop system, necessary to obtain linearity

from the transmitter and avoid splattering power into adjacent channels• Performs training functions for proper linearization of the transmitter• Provides synthesizer for setting 1st IF to 157.3 MHz

LNODCT2 IC • Up converts the baseband data to the IF freq• Down converts the IF feedback signal to baseband• Performs training functions for proper linearization of the IF path• Acts as a stand-alone Cartesian feedback system

Frequency Synthesizer Circuitry

• Consists of a phase-locked loop and VCO to provide a LO signal to the LNODCT1 for up-conversion and for down-conversion of the feedback signal from PA

• Provides LO signal to discrete mixer stage of reference path for 2nd up-conversion

774..785 MHz VCO2

• Provides LO signal to discrete mixer stage for 2nd up-conversion to Tx frequency• Provides LO signal to LNODCT1 for up-conversion and down-conversion via

mixing it with 157.3MHz.

157.3 MHz VCO1

• Provides LO signal to LNODCT2 IC for IF up-conversion• Mixes with 774..785 MHz VCO freq to provide LO freq to LNODCT1 IC.

Regulator Circuitry

• Provides a regulated voltage to various ICs and RF devices located on the Exciter

Linear RF amplifier Stages

• Amplifies the RF signal from the LNODCT IC and reference path to an appropriate level for input to the PA

Programmable Logic Array (PLA)

• Accepts clock and serial DSP data from BRC; formats the data to meet LNODCT1 and LNODCT2 requirements

• Routes SYNC and train data to LNODCT1• Routes SYNC, train, and data to LNODCT2• Outputs Amp on/off control signal during TRAIN/non-TRAIN interval• Accepts SPI addresses for various ICs from BRC and decodes the SPI addresses• Serves as the main interface between the synthesizer, LNODCT1, LNODCT2 IC,

A/D, EEPROM, vblin DAC, and BRC via SPI bus

11 - 18 6866538D01-CFebruary 2005

Base Radio

Memory Circuitry

The memory circuitry consists of an EEPROM located on the Exciter. The BRC performs all memory read and write operations via the SPI bus. Information stored in this memory device includes the kit number, revision number, module specific scaling and correction factors, and free form information (scratch pad).

A/D Converter Circuitry

Analog signals from various areas throughout the Exciter board are fed to the A/D converter. These analog signals are converted to a digital signal and are periodically monitored and controlled by the BRC.

Some of the signals monitored include the regulated voltages, the analog power monitor (APM), the 774..785 MHz PLL circuit and internal signals.

PLA Circuitry

The PLA interfaces between Exciter and BRC for SPI address decoding. The SPI address is asserted from BRC to PLA and PLA decodes the asserted address and links the SPI communication between IC in Exciter to BRC.

The PLA also formats serial digital baseband signal from DSP and converts the serial data to I & Q parallel output data. Other function of PLA is to generate the 2.4 MHz reference clock for LNODCT IC and SYNTH IC.

LNODCT IC Circuitry

The LNODCT IC is a main interface between the Exciter and BRC. Digitized signals are sent via the DSP data bus from the Digital Signal Processors of the BRC to the exciter. These data signals are clocked via the DSP clock signal provided by the Receiver.

The differential data clock signal is provided to PLA and PLA generates the reference signal to the internal synthesizer circuit of the LNODCT1 IC. The LNODCT1 compares the reference signal with the output of the 157.3 MHz Voltage Controlled Oscillator. IF the VCO output is out of phase or differs in frequency, correction pulses are sent to the Oscillator and the VCO output is adjusted.

LNODCT1 IC does up-conversion the baseband data received from the BRC to Tx freq and down-converts feedback Tx frequency from PA to baseband.

LNODCT2 IC does up-conversion the baseband data received form the BRC to 1st IF (157.3 MHz) and down-converts the 1st IF feedback to baseband.

The Serial Peripheral Interface (SPI) bus is use to communicate with the LNODCT ICs. The SPI bus serves as a general purpose bi-directional serial link between the BRC and other modules of the Base Radio, including the Exciter. The SPI bus is used to send control and operational data signals to and from the various circuits of the Exciter.

6866538D01-C 11 - 19February 2005

Base Radio

Synthesizer Circuitry

The synthesizer circuitry consists of the Phase-Locked Loop (PLL) CI and associated circuitry.

The output of this circuit is combined with the 774..785 MHz VCO to supply a Local Oscillator (LO) signal to the LNODCT IC and discrete mixer.

An internal phase detector generates a logic pulse in proportion to the difference in phase or frequency between the reference frequency and loop pulse signal.

If the reference frequency is faster than the VCO feedback frequency, an up signal is output from the PLL IC. If the reference frequency is slower than the VCO feedback frequency, a down signal is output from the PLL IC. These pulses are used as correction signals and are fed to a charge pump circuit.

The charge pump circuit generates the correction signal and causes it to move up or down in response to the phase detector output pulses. The correction signal is passed through the low-pass loop filter to the 774..785 MHz VCO circuit.

774..785 MHz Voltage Controlled Oscillator (VCO2)

The 774..785 MHz VCO circuit generates the main LO signal for LNODCT1 IC via offset mixer and main LO signal for discrete mixer in reference path.

The VCO requires a very low-noise DC supply voltage. The oscillator is driven by a Super Filter that contains an ultra low-pass filter. The Super Filter obtains the required low-noise output voltage for the oscillator.

The output of the oscillator is tapped and sent to the VCO feedback filter. This feedback signal is supplied to the Synthesizer circuitry for the generation of correction pulses.

The untapped output of the 774..785 MHz VCO is split to provide the main LO for LNODCT1 IC via offset mixer and the discrete mixer in reference path.

Via the Tx frequency issued to the Base Radio through MMI programming the VCO generates an LO frequency of 774.7 to 784.7 MHz.

157.3 MHz Voltage Controlled Oscillator (VCO1)

The 157.3 MHz Voltage Controlled Oscillator 157.3 MHz VCO provides a LO signal to the LNODCT 2 IC for the 1st IF (157.3 MHz) up-conversion and input to the offset mixer.

Regulator Circuitry

This circuitry generates five voltages of +3 VDC, +3.3 VDC, +5 VDC, +10 VDC, and +11.8 VDC. The +11.8 VDC, +10 VDC and +5 VDC voltages are obtained from the +14.2 VDC backplane voltage, and the 3 VDC, +3.3 VDC voltages are obtained from the +5 VDC backplane voltage. These voltages are used to power various RF devices of the Exciter.

Linear RF Amplifier Stages

This circuitry is used to amplify the RF signal from LNODCT1 IC, and the signal from the reference path mixer prior to the summing junction, to an appropriate level for input to the PA.

Power Amplifier

PA Overview

The Power Amplifier (PA), in conjunction with the Exciter, provides the transmitter functions for the Base Radio. The PA accepts the low-level modulated RF signal from the Exciter and amplifies the signal for transmission via the RF output connector.

The power PA contains five hybrid modules, three pc boards, and the module heatsink/housing assembly.

The PA connects to the chassis backplane using a 96-pin DIN connector and three blindmate RF connectors. Two TORX screws secure the PA to the chassis.

Specifications of the transmitter circuitry, including the Exciter and PAs, are provided in “Base Radio Overview” on page 11-1. Figure 11-9 shows the PA with the cover removed.

Theory of Operation

Table 11-9 describes the basic functions of the PA circuitry. Figure 11-10 shows a functional block diagram of the PA.

DC/Metering Board

The DC/Metering Board provides the interface between the Power Amplifier and the Base Radio backplane. The preamplified / modulated RF signal is input directly from the Exciter via the Base Radio backplane.

The RF input signal is connected, through a Voltage Variable Attenuator (VVA), to the input of the Linear Driver Module (LDM). The RF feedback signal is fed back to the Exciter, where it is monitored for errors.

The primary functions of the DC/Metering Boards is to monitor proper operation of the PA and to set PA gain via the VVA. This information is forwarded to the Base Radio Controller (BRC) via the SPI bus. The alarms diagnostic points monitored by the BRC on the PA include the following:

• Forward power

• Reflected power

• PA temperature sense

11 - 24 6866538D01-CFebruary 2005

Base Radio

RF Splitter Board

The RF Splitter of this board accepts the amplified signal from the LDM. The primary function of this circuit is to split the RF signal into three separate paths. These three RF outputs are fed directly to three separate Linear Final modules where the RF signals will be amplified further.

Linear Final Module

The RF signals from the outputs of the RF Splitter are input directly into the Linear Final Module (LFM) for final amplification. The LFM’s contain amplifier circuits that amplify the RF signal to a total of approximately 103 Watts average power (218 Watts peak envelop power (PEP)).

Interconnect Board

Routes the output of the LFM’s to the peripheral module.

Peripheral Module

The RF combiner portion of this board accepts the amplified signal from 3LFM’s and combines the three.

The RF signal is then coupled to the Exciter so that it can be monitored. The RF output signal is then passed through a circulator that acts as a protection device for the PA in the event of high reflected power.

A power monitor circuit monitors the forward and reflected power of the output signal. This circuit provides the A/D converter on the DC/Metering board with input signals representative of the forward and reflected power levels. Output power at this point is approximately 80 Watts average (169 Watts PEP).

For forward power, a signal representative of the measured value is sent to the BRC via the SPI bus. The BRC determines if this level is within tolerance of the programmed forward power level. If the level is not within certain parameters, the BRC will issue a warning to the site controller and may shut down the Exciter.

Reflected power is monitored in the same manner. The BRC uses the reflected power to calculate the voltage standing wave ratio (VSWR). If the VSWR is determined to be excessive, the forward power is rolled back. If it is extremely excessive, the BRC issues a shut-down command to the Exciter.

Fan Module

The PA contains a fan assembly to help keep it within a normal operating temperature through the use of a cool air intake. The fan assembly contains three individual fans that are directed across the PA heatsink.

The current drain of the fans is monitored by the DC/Metering board. A voltage representative of the current drain is monitored by the BRC. The BRC flags the site controller if an alarm is triggered. The PA LED on the front panel of the BRC is also illuminated, however the PA does not shut down.

DC Power Supply

DC Power Supply Overview

The DC Power Supply provides DC operating voltages to the various Base Radio FRUs. It accepts input voltage sources from -41 to -60 VDC. This input source may be grounded at either its positive or negative end.The DC Power Supply is designed for sites with an available source of DC voltage that is nominally -48 VDC. On initial start up, the supply requires a voltage of -44 VDC to -48 VDC. If the voltage hereafter drops out of the range of -41 VDC to -60 VDC, the DC Power Supply reverts to a quiescent mode and does not supply any output power.

Outputs supplied from the DC Power Supply are 28.6 VDC at up to 18.0 A, 14.2 VDC at up to 8.0 A, and 5.1 VDC at up to 3.0 A; all referenced to chassis ground. The supply is rated for 575 Watts of continuous output power up to 45 °C (113 ° F) inlet air. The 28.6 VDC output is then linearly derated to 15 A at 60 °C (140 °F).

The DC Power Supply consists of the Power Supply and front panel hardware. The DC Power Supply interconnects to the system backplane via edgecard connections. Two TORX screws secure the DC Power Supply to the chassis.

Figure 11-11 shows the front view of the DC Power Supply.

3X Receiver

Overview

The 3X Receiver provides the receiver functions for the Base Radio. It consists of a receiver board, a slide-in housing, and associated hardware. The 3X Receiver incorporates one to three diversity branches on a single module. Figure 11-12 shows a top view of the 3X Receiver with the cover removed.

Figure 11-12 3X Receiver (with cover removed)

Definition and Identification

The 3X Receiver kit contains three receivers on a single board. This allows a single module to provide three-branch diversity BR functionality. To identify 3X Receiver boards in the EBTS, use the MMI command get_rx1_kit_no, this command reports the kit number from the receiver’s EEPROM.

Diversity Configuration

There is a software parameter used for diversity purposes with the 3X Receiver. The parameter is the rx_fru_config parameter. The diversity issues to consider are described in the following paragraph. This parameter can be accessed through the MMI commands using the Motorola password.

6866538D01-C 11 - 31February 2005

Base Radio

Diversity Uses and Cautions

The 3X Receiver board can be used in one, two, or three branch diversity systems. The number of active receivers is determined by the rx_fru_config parameter stored on the Base Radio Control (BRC) board. The rx_fru_config parameter must be set properly for the diversity system in use.

To view the rx_fru_config parameter, use the MMI command get rx_fru_config. The configuration of each Base Radio can be changed in the field to match the number of receivers connected to antennas. To change the rx_fru_config parameter, use the command set rx_fru_config yyy, where yyy is the active receiver (yyy is 1 for one branch, 12 for two branch diversity). For the system to work optimal, the rx_fru_config parameter must match the number of receivers connected to antennas.

There will be significant system degradation if the rx_fru_config parameter is not set properly for the diversity system in use.

Theory of Operation

The 3X Receiver performs highly selective bandpass filtering and dual down conversion of the station receive RF signal. A custom Receiver IC outputs the baseband information in a differential data format and sends it to the BRC.

Table 11-13 lists the 3X Receiver circuitry and Figure 11-13 shows a functional block diagram for the 3X Receiver.

Frequency Synthesiser and VCO Circuitry

The synthesiser and VCO circuitry generate the RF signal used to produce the 1st LO injection signal for the first mixer in all the Receiver front end circuits. Functional operation of these circuits involves a Phase-Locked Loop (PLL) and VCO.

Table 11-13 3X Receiver Circuitry

Circuit Description

Frequency Synthesiser Circuitry

Consists of a phase-locked loop and a VCO. It generates the 1st LO injection signal for all three receivers.

Receiver Front-End Circuitry

Provides filtering, amplification, and the 1st down conversion of the receive RF signal. Digital step attenuators at the 1st IF are included in this block.

Custom Receiver IC Circuitry

Consists of a custom IC to perform the 2nd down conversion, filtering, amplification, and conversion of the receive signal. This block outputs the receive signal as differential data to the BRC.

Address Decode, A/D Converter, & Memory Circuitry

Performs address decoding for board and chip select signal, converts analog status signals to digital format for use by the BRC. A memory device holds module specific information.

Local Power Supply Regulation

Accepts +14.2 VDC input from the backplane interconnect board and generates two +10 VDC, a +10.8 VDC, and two +5 VDC signals for the receiver.

11 - 32 6866538D01-CFebruary 2005

Base Radio

The PLL IC receives frequency selection data from the BRC module microprocessor via the SPI bus. Once programmed, the PLL IC compares a 2.4 MHz reference signal from the BRC with a feedback sample of the VCO output from its feedback buffer.

Correction pulses are generated by the PLL IC, depending on whether the feedback signal is higher or lower in frequency than the 2.4 MHz reference. The width of these pulses is dependent on the amount of difference between the 2.4 MHz reference and the VCO feedback.

The up/down pulses are fed to a charge pump circuit that outputs a DC voltage proportional to the pulse widths. This DC voltage is low-pass filtered and fed to the VCO circuit as the control voltage. The control voltage is between +2.5 VDC and +7.5 VDC.

The DC control voltage from the synthesiser is fed to the VCO circuitry, which generates the RF signal used to produce the 1st LO injection signal.This signal is fed through a buffer to the 1st LO injection amplifier. A sample of this signal is returned to the PLL IC through a buffer to close the VCO feedback loop.

Receiver Front End Circuitry

The station receive RF signal enters the Receiver through the RF-type connector located on the back of the Receiver board. This signal is high-pass filtered, amplified and fed into the 1st mixer. The signal mixes with the 1st LO injection signal to produce a 73.35 MHz 1st IF signal.

The 1st IF signal is sent through a 4-pole bandpass filter and fed to a buffer amplifier. The buffer amplifier output signal is 4-pole bandpass filtered again and the resultant signal is then passed through a digital attenuator. This attenuation is determined by the BRC. The resulting signal is then fed to the RF input of the custom receive IC.

Custom Receiver IC Circuitry

The custom Receiver IC provides additional amplification, filtering, and a second down-conversion. The 2nd IF signal is converted to a digital signal and is output via differential driver circuitry to the BRC. This data signal contains the necessary I and Q information, AGC information, and other data transfer information required by the BRC to process the receive signal.

The remainder of the custom Receiver IC circuitry consists of timing and tank circuits to support the internal oscillator, 2nd LO synthesiser circuitry, and 2nd IF circuitry.

A serial bus provides data communications between the custom Receiver IC and the TDMA infrastructure support IC (TISIC) located on the BRC. This bus enables the TISIC to control various current and gain settings, establish the data bus clock rate, program the 2nd LO, and perform other control functions.

Address Decode Circuitry

The address decode circuitry enables the BRC to use the SPI bus to select a specific device on a specific Receiver for control or data communication purposes.

If the board select circuitry decodes address lines A2 through A5 as the Receiver address, it enables the chip select circuitry. The chip select circuitry then decodes address lines A0 and A1 to generate the chip select signals for the EEPROM, A/D converter, and PLL IC.

6866538D01-C 11 - 33February 2005

Base Radio

Memory Circuitry

The memory circuitry consists of three EEPROMs located on the Receiver. The BRC performs all memory read and write operations via the SPI bus. Information stored in this memory device includes the kit number, revision number, module specific scaling and correction factors, and free form module information (scratch pad).

A/D Converter Circuitry

Analog signals from various strategic operating points throughout the Receiver board are fed to the A/D converter. These analog signals are converted to a digital signal and are output to the BRC via the SPI lines upon request of the BRC.

Voltage Regulator Circuitry

The voltage regulator circuitry consists of two +10 VDC, a +10.8 VDC, and two +5 VDC regulators. The two +10 VDC and the +10.8 VDC regulators accept the +14.2 VDC input from the backplane interconnect board and generate the operating voltages for the Receiver circuitry.

One of the +10 VDC regulators feed two +5 VDC regulators, which outputs Analog +5 VDC and Digital +5 VDC operating voltages for use by the custom Receiver IC.

A +5.1 VDC operating voltage is also available from the backplane interconnect board to supply +5.1 VDC to the remainder of the Receiver circuitry.

Safety Information SummaryThis appendix contains a summary of the warnings and precautions to be taken into account in the EBTS PR 3.2 documentation. Note that it is not an exhaustive list of precautions and safety measures that should be observed. Please ensure that all local and site safety measures are implemented before carrying out any function with the EBTS or associated equipment.

Any device (i.e., power supply) providing isolation between the mains and the EBTSs must provide reinforced insulation to hazardous voltages. The DC power source providing power to the EBTSs shall comply with requirements specified for a safety extra low voltage circuit (SELV) per EN60950, 1995.

Always use appropriate lifting equipment and number of personnel whenever moving an EBTSs equipment cabinet to reduce the risk of tipping or injury, a fully configured equipment cabinet weighs over 270 kg (600 lbs). Tipping can result in serious injury and extensive equipment damage.

The Dimetra IP EBTSs system manual is intended for trained technicians experienced with Motorola base radio equipment or similar types of equipment.

The Site Controller board contains a lithium battery. Refer to local regulatory requirements for proper disposal.

Use extreme caution when wearing a conductive wrist strap near sources of high voltage. The low impedance provided by the wrist strap also increases the danger of lethal shock should accidental contact with high voltage sources occur.

6866538D01-C B - 1February 2005

Never use a bare or damaged wire for the connection of chassis ground or other electrical wiring. Damage to equipment or potential injury to personnel could result.

Follow all manufacturer’s instructions regarding protective gear and usage when using nail gun.

Follow all manufacturer’s instructions regarding protective gear and usage when using concrete nails and hammers.

Make sure all power to the power supply equipment is off to prevent accidental contact with high energy and injury to personnel

RF energy hazard. Disconnect power to all base radios in the cabinet to prevent injury while disconnecting and connecting antennas

BR weight exceeds 27 kg (60 lbs). To remove the BR, first remove the PA and PSU, then remove the BR from the cabinet. If required, remove further modules to decrease the weight of the BR before removal. Ensure that the BR is fully supported when BR is free from mounting rails.

Ensure a good connection between the electrical system ground and site ground to prevent excessive voltage potential between the two ground systems during lightning strikes

Equipment has two independent power sources (A and B). To remove power from equipment, disconnect both power sources.

Danger of explosion if the TSC battery is replaced incorrectly. Replace battery only with the same or equivalent type recommended by manufacturer. Dispose of used batteries according to the manufacturer’s instructions.

B - 2 6866538D01-CFebruary 2005

Static Sensitive Precautions

The static grounding wrist strap (Motorola P/N 4280385A59) must always be used when handling any board or module within the EBTS. Many of the boards or modules used in the EBTS equipment are vulnerable to damage from static charges.

Extreme care must be taken while handling, shipping, and servicing these boards or modules. To avoid static damage, observe the following precautions:

• Prior to handling, shipping, and servicing EBTS equipment, connect a wrist strap to the grounding clip on the Equipment Cabinet. This discharges any accumulated static charges.

• Avoid touching any conductive parts of the module with your hands.

• Never remove boards or modules with power applied to the unit (hot-pull) unless you have verified it is safe to do for a particular board or module. Make sure the unit will not be damaged by this. Several boards and modules require that power be turned off before any boards or modules are removed.

• Avoid carpeted areas, dry environments, and certain types of clothing (silk, nylon, etc.) during service or repair due to the possibility of static buildup.

• Apply power to the circuit under test before connecting low impedance test equipment (such as pulse generators). When testing is complete, disconnect the test equipment before power is removed from the circuit under test.

• Be sure to ground all electrically powered test equipment. Connect a ground lead (-) from the test equipment to the board or module before connecting the test probe (+). When testing is complete, remove the test probe first, then remove the ground lead.

• Lay all circuit boards and modules on a conductive surface (such as a sheet of aluminium foil) when removed from the system. The conductive surface must be connected to ground through 100k.

• Never use non-conductive material for packaging modules being transported. All modules should be wrapped with static sensitive (conductive) material. Replacement modules shipped from the factory are packaged in a conductive material.

You must be familiar with Man-Machine Interface (MMI) commands and their usage prior to performing procedures in this documentation. Improperly applying MMI commands can result in equipment damage.

Do not attempt to make a resistance check of the GPS antenna. Damage to the active devices within the antenna element may result

Do not transmit to an antenna under any circumstance unless those frequencies are licensed.

Do not key any base radio with the Signal Generator directly connected to a Tx antenna port. Damage to generator will result

6866538D01-C B - 3February 2005

Some commands executed during Conformance Testing will bypass normally available alarms and protection associated with normal EBTS operation. Therefore, it is imperative to adhere to all cautionary information and follow instructions exactly as written in the procedures.

Planned Maintenance InspectionIn order to assist maintainers of Motorola Dimetra products, Motorola publishes advice for recommended Planned Maintenance Inspections (PMI), sometimes known as Periodic Maintenance Inspection or Information. For each Motorola Part Number, the Inspection Schedule indicates whether any PMI action is required/recommended, the regularity of the recommended/required action, and a brief description of the activity. The Inspection Schedule also indicates Motorola's recommended PMI testing activities that should be carried out as part of the PMI Schedule.

The PMI Inspection Schedule should always be read in conjunction with the relevant Motorola or Motorola 3rd party suppliers’ Standard Product Manuals and any Technical Information Bulletins (TIB's), where the methods of access and other information will be located.

In additional to the Planned Maintenance Inspections related to those specific Part Numbers below Motorola recommends that basic functional testing should be carried out every 12 months. These functional tests should include RF Power Measurements, RF Frequency measurements, and Bit Error Rate measurements.

Motorola also recommends that the antennae, PSU / UPS and any Air Conditioning equipment also be inspected and functionally tested at regular intervals or as advised by the respective manufactures.
