7. GENERAL INFORMATION

The Hiperion ATL-MSAS *Please contact ATECIL for the latest Data Interfaces available.

This documentation covers the installation and maintenance of ATL-GX IDU (Indoor Unit) for both 1+0 and 1+1 configurations, and is intended to be read in conjunction with the Hiperion Antenna Installation Manual, the Hiperion ODU Installation Manual and ATL-CB Redundancy Splitter Installation Manual.

8. SYSTEM CONFIGURATION

The following configurations are supported: 8.1.1 Unprotected (1+0)

8.1.2 Hot Standby (1+1)

Figure 8-2: Protected configuration system-hot standby, Single Antenna

In the hot standby mode, only one IDU is in Tx operation at the transmitting end, the other IDU is in Tx Standby (with the transmitting function muted). When an error occurs, the active IDU transmitter will be shut down and replaced with the standby IDU transmitter. At the receiving end, both receivers and modulators are in operation. Each receiver will receive the same RF signal and then the two demodulators will demodulate the received signal. The better of the two signals will be selected and sent as user traffic. 8.1.3 Frequency Diversity (1+1)

In the Frequency Diversity mode, the two channels are fed with the same signal resource. Data is distributed to the two channels by an equal split coupler, and then sent to the corresponding IF modules; each having the modulator and transmitter in operation. At the receiving end, each receiver and demodulator is receiving and demodulating the signals from different RF channels. The better of the two signals will be selected and exported.

Figure 8-3: Protected configuration Frequency Diversity, Single Antenna

8.1.4 Space Diversity (1+1)

In the Space Diversity mode, the best or either receive signal is exported out of the IDU. The best signal is based on a comparison of the amount of Forward Error Correction applied to the signals. The IDU’s compare each data frame and then vote on which frame matches the original, exporting this frame. True Space Diversity would normally use two antennas however it is automatically enabled when either the Hot Standby mode or Frequency Diversity mode is selected.

Figure 8-4: Protected configuration Hot Standby with Space Diversity or Frequency Diversity, Dual Antenna

Space Diversity using two antennas may be used and functionally, is automatically enabled when either the hot standby mode or frequency diversity mode is selected.

8.1.5 Unprotected (2+0)

Figure 8-5: Unprotected 2 + 0 configuration, Single Antenna

This configuration doubles the capacity of the link which utilises two ODUs at each end of the link connected to a single IDU, combined on a single antenna or on separate antennas if desired. Each ODU pair forms a single RF link carrying up to 350Mbps Full Duplex, for a total capacity of up to 700Mbps Full Duplex.

9. PRE-INSTALLATION

9.1 Warnings and Alerts

9.1.1 Radio Frequency Energies

There may be situations, particularly in workplace environments, near high- powered RF sources, where recommended limits for safe exposure of human beings to RF energy, could be exceeded. In such cases, care may be necessary to ensure the safe use of and minimal exposure to RF energy.

The equipment must not be installed or maintained in bad weather (e.g. storm, extreme temperatures and high humidity). 9.2.2 Installation Location

The mounting structure must be suitable to support the equipment weight as specified in the datasheet; including and wind loading that may apply. 9.2.3 Environmental

Humidity can affect the reliability of the equipment. It is recommended to install the equipment in the location having stable temperature and un-restricted airflow. 9.2.4 Grounding Requirement

Verify the equipment has been well grounded; this includes IDU, ODU and all cables connected. Ensure lightning protection for the antennas is properly grounded. 9.2.5 Manual Handling

During transportation and installation, take necessary handling precautions to avoid any potential physical injury to the installation related personnel and/or damage to the equipment.

9.3 GOODS INWARDS INSPECTION

Verify the number of packages received against the packing list.

Check all packages for external damage; report any external damage to the shipping carrier. If there is damage, a shipping agent should be present before unpacking and inspecting the contents because damage caused during transit is the responsibility of the agent.

Open and check each package (do not remove any items from anti-static packaging) against the packing list. In the instance where items are missing or damaged, please contact AT Electronic & Communication International Limited within 24 hours of receiving the shipment.

Do not remove items from antistatic packing until ready for installation. If damage is discovered at the time of installation, contact the shipping agent.

The following items deserve for special attention:

Check and ensure all the accessories and installation tools on the packing list are included;

Check if the model number is consistent with the order. Pay attention to the working frequency and capacity;

Check if the antenna’s diameter and its working frequency are consistent with the order.

9.4 PREPARATION

Control and safety measures should be in place before any staff member starts working at heights.



Listed below are the three levels of control measure available to protect personal from the risk of a fall, in order of preference, are:

• Erecting a physical barrier

• Providing personal fall protection

• Measures to “catch” a falling person.

9.5 LIGHTNING PROTECTION

Give consideration to the installation location to ensure that the maximum effective lightning protection is applied to the ODU and antenna. 9.5.1 Grounding the Antenna

To ensure the system is protected from lightning damage, it is vital that the antenna is effectively grounded. The tower or mast and lightning protection must be connected to the same common ground point using a low-resistance bonding conductor.

A good electrical connection from the antenna and ODU to the tower or mast using a large diameter ground wire and non-corrosive hardware.

The grounding system must comply with electrical codes and safety standards that apply to the installation location.

Verify the grounding operation is conducted by a qualified electrician to get rid of potential risks and damages.

The ground must be periodically checked for low “Earth Resistance” and corrosion.



Figure 9-1: Grounding of Tower and Equipment.

9.5.2 Antenna and Lightning Protection

Lightning protection is designed to protect people, property and equipment from injury or damage from both a local and near by adjacent lightning discharge. Sound lightning protection design is an indispensable element of a grounding system used to protect the equipment from transient and/or electrostatic discharge. The components required to protect the microwave radio installation are as follows:

Part No ATL-AN10MF70 (One Surge Arrestor is installed at each end of the IF Cable) 1 + 0 configuration: 2 x Surge Arrestor 2 + 0 configuration: 4 x Surge Arrestor 1 + 1 configuration: 4 x Surge Arrestor

For optimal protection, one Surge Arrestor is located at the “N-Type” connector of the ODU and the other is located at the “N-Type” connector of the IDU.

The Ground Kit is installed on the IF Cable at the point of entry into the equipment room or shelter or building. As the Surge Arrestor is designed to be sacrificial, the location should allow for easy installation and removal.

10. ANTENNA ASSEMBLY

Antennas which have multiple components must be re-assembled carefully to ensure mechanical performance is achieved. 10.1.1 Feeder Cable Assembly

Take normal precautions when preparing and handling feeder cables and waveguides to ensure they are not damaged by their own weight. Cable should not be pulled with a radius less than that determined for the installed cable/waveguide. Due to limitations of side bearing pressure, it is recommended that larger radius bends be used. Inspect the cable/waveguide ends for small metal fragments; remove unwanted objects before each connector is installed. Always protect the cables and waveguides from damage, use cable clips where needed. 10.1.2 Moisture Proofing

Extreme care should be exercised with waveguides before and after installation to ensure that moisture does not enter the waveguide. Keep the waveguide dry while in storage with ends tightly capped. Connectors, and fittings, to be located outdoors should be made mechanically tight, and with any factory supplied sealing fittings installed. Moisture problems in antenna systems are usually traced back to connectors which have NOT been properly protected. Moisture protection may be required which includes, dry nitrogen, compressors or dehydrators. 10.1.3 Drip-Loop

AT Electronic & Communication Limited International recommends that every horizontal cable entry to the antenna feed, forms a 'U' before its entry to equipment and antenna. This prevents any accumulation of water on the cable.



10.1.4 Antenna Connections

The antenna has been designed for all cable/waveguide entries from the rear of the antenna feed assembly.

12.2.2 Grounding the IDU

The IDU should be properly grounded before connecting any other cables. A screw terminal located on the IDU frame is used for grounding. This ground terminal must be electrically connected to the site earth ground using the supplied cable BVV 2.5.

Figure 12-5: IDU Earth Post

13. IF CABLE

The design of the Outdoor Unit allows low cost coaxial cable to be used to interconnect the IDU to the ODU.

Note: ATECIL recommends the use of low loss, 100% shield coaxial cable with an Ultra Violet stabilised outer jacket.

The following tables indicate the maximum lengths for various types of coaxial cable (example is Times Microwave®), when using either a 24 VDC or 48 VDC power supplies and standard or high power ODUs.

14. ANTENNA INTRODUCTION

The Microwave Antenna is of a parabolic design that consists of a reflector, feed and tower mount. Typically, there are two types of antenna: High Performance (HP) Parabolic Antenna and Standard Performance (SP) Parabolic Antenna. With additional shield and radome applied, the HP Parabolic Antenna is of higher efficiency, with superior Front/Back Ratio as well as excellent anti-corrosion proofing properties. The antenna is mainly used for directing the RF energy into and out of the ODU in a particular direction. ATECIL provides a wide range of Parabolic Antennas with different sizes for all operating bands of our Hiperion product line. The table below list all antennas available by radome size and frequency band.

14.1 Antenna Installation

14.1.1 KIT OF PARTS

The antennas are shipped to the customer in either a cardboard carton for the small antennas or a wooden container. Antennas are shipped with partially pre-assembled mounts, other items typically packed with the antenna include:

A Ring spanner

Silicon sealant The antenna assembly is made up of three main components:

Radome and feed assembly

Mounting Bracket

Pole mounting clamps



14.1.2 Tools Required

Philips screwdriver

Open Spanner

14.2 Antenna Installation Procedure

With the complete antenna packaging moved to the final installation site, exercise care in the use of the tools used to open and remove the lid. Ample packaging material, protecting the antenna during shipment, may be discarded with the packaging container at the end of the installation. The antenna is pre-assembled including all the mounting fixtures prior to shipment. Before commencing with pole or tower mounting, the installer needs to unscrew and remove the mounting screws and bolts. The antenna mounting rack can then be separated from the equipment in preparation for subsequent installation. Depending on antenna provided, it may be necessary to construct the antenna on site before installation. This section uses the 0.3 m and 0.6 m antenna installation as examples. Refer to the publication “ATL-Hiperion Antenna Installation Guide” for the installation of other antenna sizes. 14.2.1 Parabolic Antenna Installation

Locate and position the antenna onto the mounting pole, identify the U-shape bracket, assemble and mount to the pole.

Hold the mounting rack with one hand, and mount the two U-shape brackets onto the upper and lower pairs of the M10 bolts with the other hand.

U-shape brackets M10 bolt

17. ANTENNA ALIGNMENT

17.1 Antenna Pre-Alignment

17.1.1 Tools Required

• Compass • Inclinometer • Spanners • voltmeters

17.1.2 Initial Set Up

Antenna alignment requires staff at each end of the link. A path profile analysis will provide each site with the required installation elevation, azimuth and bearing information, for initial antenna positioning. Ensure this information is available at each site. This is sufficient for the antenna to be pointed in the general direction as fine tuning will take place during alignment. For azimuth and elevation alignment, arrange each end to be on the assigned frequency to minimise any possible interference. Alignment involves quite a bit of fine tuning, which is an iterative process and the objective is to maximise the receive signal at each end the hop. Before proceeding to antenna pre-alignment, ensure each end of the hop is equipped with a known working Voltmeter.

17.2 Antenna Pair Identification

There may or may not be in-band interference at either site, however identify and isolate the wanted RF signal in the presence of unwanted signal using the calculated RSL. For each ODU, a unique ‘lookup table’ is supplied to specify the relationship between RSL and RSSI level. Ensure the serial number of the ODU matches the correct ‘lookup table’ before proceeding.

Figure 17-1: Typical RSL Vs RSSI Curve



RSL (dBm) Vbnc (V)

-25 4.19

-30 3.87

-75 1.06

-80 0.75

-85 0.44

-90 0.12

Table 17-1: Typical RSL Vs RSSI Volts

The path analysis documents should be checked for the expected RSL. Allowance should be made for an RSL over a small range of say 10 dB ~ 15 dB. Correlate the data in the ‘lookup table’ against the RSSI reading along all points of the RSL range.

The antenna pair is identified when measured RSSI level matches against the corresponding RSL values specified in the lookup table. 17.2.1 Antenna Fine-Alignment

Each ODU has a BNC connector, for DC voltage measurement by a voltmeter. A meter with an analogue movement is the best type to use. This is a RSSI indication, and is monitored by the multimeter. RSSI is indicated by a voltage reading, and varies as azimuth and bearing adjustments are made. Each antenna is adjusted, one at a time, until a maximum peak in RSSI is found and no further adjustment of either antenna causes any further increase in RSSI voltage.



Figure 17-2: ODU RSSI profile for antenna

The above figure represents the RSSI level as the antenna is being brought into alignment. Note that there are several peak with one dominate peak. Location of the optimal signal strength should be at the maximum of its RSSI profile. The local antenna is paned from a slightly high position above the bore site of the antenna across the peak in RSSI signal, then lowered slightly, and panned in the other direction, until the dominate peak is found.

Figure 17-3: Panning Antenna

With the antenna positioned on the maximum peak, this procedure is repeated at the remote antenna. This is repeated several times for each antenna until no further increase in RSSI voltage is noted.

17.3 Antenna Adjustment

17.3.1 Antenna Azimuth Adjustment

18. ATL-GX IDU FUNCTIONALITY

18.1 Setting ODU parameters

18.1.1 Frequency Point Selection

The operational frequency of the ODU can be configured through the monitoring system such as the NMS, or via a web browser. 18.1.2 Transmit Power Control Function

Through the monitoring system, the ODU Tx output power can be configured. 18.1.3 Automatic Gain Control (AGC)

The ODU automatically controls the gain of the receiver amplifiers to ensure that the IF level is consistent for delivery to the IDU. This ensures the performance of the entire system. 18.1.4 Digital Signal Processing (DSP)

Digital Signal Processing (DSP) is implemented for the digital filtering and processing of modulated and demodulated signals. Using DSP, the signal-to-noise ratio (SNR) is reduced and the performance of a communication system is then enhanced.



In parallel with the above, the application of advanced Forward Error Correction (FEC) enables a number of errors to be detected and corrected without requiring retransmission, thus reducing the RSL threshold and improving the performance of system gain. 18.1.5 Signal Processing

The following signals are processed by the IDU:

• Ethernet Interface: for LAN signal input and output

• NMS Interface: for monitoring and management.

• EOW Interface: provides voice connection between ends of a radio link.

• Auxiliary Data Channels: providing users with serial data interfaces via “AUX” interface. The RS-232 or RS-422 protocol is available for these interfaces. Both synchronous and asynchronous modes are provided. Auxiliary data can be transmitted through this channel.

18.1.6 MSE

Mean Squared Error (MSE) is similar to Signal to Noise Ratio (SNR) except that MSE accounts for distortion and interference in addition to noise power. Distortion may come from several sources such as IF cables that are improperly constructed, and path degradation caused by path anomalies such as multi-path or Fresnel zone encroachment. Interference may come from other co-sited transmitters on the tower, from high power transmitters in the indoor shelter where the IDU is located or from other adjacent transmitters. Distortion and Interference causes degradation of the receive signal by modifying the received modulation. There are maximum acceptable MSE values for each type of modulation which are useful in determining the quality of the link however the higher level of modulation, the lower the MSE value must be. The MSE value reported is only relevant to one Transmit – Receive path, so the MSE of each path must be evaluated to verify the link is operating correctly. The lower the value of MSE the better the Link quality, for example, a MSE value of -35dB is better than a value of -30dB. The table below shows the maximum MSE value to expect in IF Loopback, Normal Operation, and Absolute Maximum.

MSE Expected and Maximum Values (dB)

-28 -25 -22 -19 -16 -9

Table 18-1: Expected and Maximum MSE Values



18.1.7 ATPC

Automatic Transmit Power Control (ATPC) allows the link elements to automatically adjust the output

power of the ODU‟s to achieve the ATPC Trigger Level.

If the RSL (Received Signal Level) of the local ODU drops to a level lower than the ATPC Trigger

Level, i.e. RSL < ATPC Trigger Level, the local MW equipment will send a power increase request to

remote equipment. When the remote MW equipment receives the power increase request from the

local equipment, it will increase the output power. If the increasing output power is higher than the

maximum output power of ODU, then remote ODU will use the maximum output power.

Figure 18-1: ATPC action

If the RSL of the local ODU is 6dB higher than the ATPC Trigger Level, i.e. RSL > ATPC Trigger Level + 6, the local ODU will send a power decrease request to the remote ODU. When this request is received, the remote ODU will decrease the output power. If the output power is lower than the minimum output power of ODU, then it will use the minimum output power.

18.1.8 ACM

Adaptive Coding and Modulation (ACM) was designed to help operators maximize spectrum usage

and increase the capacity of their backhaul links over any given channel bandwidth, under any

weather condition, at any link budget.



Adaptive Coding and Modulation refers to the automatic adjustment that a wireless system can make

in order to optimize over-the-air transmission and prevent weather-related fading from causing

communication on the link to be disrupted.

When extreme weather conditions, such as a storm, affect the transmission and receiption of data

and voice over the wireless network, an ACM-enabled radio system automatically changes

modulation and/or coding allowing real-time applications to continue to run uninterrupted.

Varying the modulation and/or coding will also vary the amount of bits that are transferred per signal,

thereby enabling higher throughputs and better spectral efficiencies.

Figure 18-2: ACM modifying Link Capacity

18.1.9 Monitoring and Network Management

Monitoring and network management is available for the system. In addition to the operational parameters, a number of other parameters such as status, internal temperature, transmit power and frequency, receiving and transmitting levels and system alarms can also be monitored.

18.2 Connecting the IDU

A DC power cable is used for the power supply to the ATL-ECI IDU through the power connector located on the front panel. To connect the power cable to the power source, the following items must be noted.

Make sure the IDU power is OFF.

Connect the red wire to the “+“Terminal of the power source.



Connect the black wire to the “-” Terminal of the power source.

Before connecting the power cable to the equipment, check and ensure the voltage and polarity meet the requirements with a multi-meter.

21.4.1 LAN Speed Test V1.0

“LAN Speed Test V 1.0” is a FREE utility designed to accurately measure LAN speeds. It does this by writing a file (the user chooses the size) to a folder (chosen by the user), clears windows file cache, reads the file back, clears the cache again, deletes the file, and displays the results. LAN Speed Test V 1.0 is a portable windows application that works with Windows 98SE, Windows ME, Windows 2000, Windows 2003, Windows XP, Windows Vista, & Windows 7. It can be run from a USB Memory Stick, for example, does not require any installation, does not use DLL’s and does not change the Windows Registry. The results provide meaningful results with some limitations. LAN Speed Test V 1.0 can be downloaded from http://www.totusoft.com/downloads.html.

Figure 21-5: LAN Speed Test V 1.0 Screen Snapshot

21.4.2 LAN Speed Test V 2.0

“LAN Speed Test V 2.0” is a more advanced, low cost utility, designed to be a rock solid tool to measure your file transfer and network speeds (wired & wireless) easily and accurately. It does this by building a file in memory, then transfers it both ways (without the effects of windows file caching) while keeping track of the time, and then does the calculations. LAN Speed Test 2.0 has a number of advanced features and uses a powerful process to measure your LAN speed that is much faster and more accurate than the free version LAN Speed Test V 1.0. Some of LAN Speed Test v2.0 Features include...

Completely portable - No installation needed

http://www.totusoft.com/downloads.html



Small file size of 126KB and can run from a hard drive, USB Flash drives, etc.

Compatible with all Windows 2000 & up

Very Fast! Most tests are less than 1 minute

Test packet sizes up to 9 GB while taking a maximum of just 10 MB of RAM on your system

Progress window that displays progress bar and allows user to cancel at any time

LST Server support for a more accurate True network speed without hard drive limitations

Test WAN speed with LST Server

Network Scan with the ability to Ping test any node on the network

Log viewing screen with ability to add notes

Scheduling runs now an option with logging and new Command Line format

Open/Save option to .csv file

Individual profiles automatically saved to .ini file to remember all settings

Selectable Speed Measurements

Command Line Mode which allows Network Administrators to start the test from the client's workstation and view the log file from anywhere on the network.

The results provide highly meaningful results. LAN Speed Test V 2.0 can be downloaded from http://www.totusoft.com/downloads.html.

21.4.3 LAN Speed Test LST Server

LAN Speed Test LST Server is, low cost utility, providing additional features for LAN Speed Test. By using this configuration the client talks directly to the server through the network with no hard drive limitations.




This gives more accurate results of True network performance on the client screen. LST Server also makes it possible to test your WAN connection. Some of LST Server Features include...

Completely portable - No installation needed

Small file size of 69KB and can run from a hard drive, USB Flash drives, etc.

Compatible with all Windows 2000 & up

Very easy to use

Log Window and logging options

Server can handle multiple client connections

Server supports multiple NICs (Network Adapters)

It is not necessary to use LST Server, but desirable. Using LAN Speed Test with LST Server writes the test file to the server's memory and takes the hard drive out of the picture for truer network speed results. Using LAN Speed Test without LST Server, writes the test file to another computer's hard drive. Tests will show slower speeds, but is more of a real-world test as most of the time you are writing files to other hard drives (file servers, etc.). LST Server can be downloaded from http://www.totusoft.com/downloads.html.

22. MAINTENANCE

After equipment commissioning, no further maintenance by hand is required. After NMS commissioning, the monitoring centre can control the operational status of all of the equipment in the network. The following regular inspections are recommended to ensure long life system performance.

Antenna systems should be inspected once a year by qualified personnel to verify proper installation, maintenance, and the condition of equipment. This should include a comparison of the RSL with the RSL as noted in the Commissioning Document. Note that for this comparison, weather conditions should be similar to those at the time of installation.

The Station and System Earths should be inspected every 12 months for integrity and low ground resistance.

Periodically check for proper connection and tightening of all cables and mounting fixtures. Make sure that the ATL-GX ODU has not been damaged, disassembled or otherwise tampered with, and remains properly grounded as described in the previous sections.

Cleaning the surface of the equipment regularly to remove dust and other deposits like salt for example, to ensure the normal operation and prolonging the useful life of the equipment.

The Surge Arrestors are designed to be sacrificial. Inspect the Surge Arrestor devices for integrity. Replace any that do not meet electrical specifications or appear suspect on physical examination.

The installation location for ATL-GX ODU should remain well ventilated.

ATECIL disclaims any liability or responsibility for the results of improper or unsafe installation practices.

The ATL-GX IDU and ODU have no user serviceable parts internally. In the event of a hardware fault, the faulty unit must be replaced with a known functional unit and returned to ATECIL for repair.
