Chapter 1 Introduction

1.1 Overview of BTS Local Maintenance

The BTS local maintenance software is installed onto a PC (a laptop is preferred),

which is connected to the BTS with serial communication cable. The local

maintenance of BTS can then be implemented via the MMI in the maintenance cavity

of the mini BTS.

1.2 Introduction to BTS Local Maintenance Console

It is possible to perform operations to the logical objects or boards of BTS at the near

end maintenance console. The following chapters will detail the information of various

logical objects.

I. Logic Objects

In BTS terminal maintenance, the logic objects comprise: Site, Cell, BT (Baseband

Transceiver), CH (Channel), RC (Radio Carrier).

The relationship of these logic objects is shown in Figure 1-1.

The status of logic objects:

1) Management state

z It is force-configured by the administrator indicating allowance or prohibit to use

the resources.

z There are three values for the management states:

z Locked: disconnect the transmitting and receiving of the radio interface and/or

ground baseband.

z

Unlocked: connect the transmitting and receiving of the radio interface and/orground baseband.

z ShutDown: hold the existing coiomunications until the services are released, and

new users are prevented from access to the resources.

Note:There is no ShutDown state for cells.

The site management state is only involved in the getting of management right.

Getting the management right or not determines whether the user can perform data

configuration through the O&M terminal.

2) Operational state

It indicates whether the resource is in normal operation or available.

Two values for this: Enabled, Disabled.

II. Introduction to the Interface of Local Maintenance Console

Figure 1-2 shows the interface of the local maintenance console. The interface can be

divided into 3 areas: window of operational objects (left white window) in which

objects can be selected; operation option window (right white window) in which

specified operation can be performed to the selected objects, such as software

loading, hierarchical resetting, etc; the aqua blue window below is the alarm window,

which displays the alarm is any.

Chapter 2 Operation Preparation

Before the implementation of BTS local maintenance, it is necessary to finish some

simple preparations: the local O&M cable connection, and startup of local O&M

maintenance console.

Note:MMI operations of all BTS3X transceivers are similar. For description in this manual,

BTS3012 is cited as an example.

2.1 Connecting Terminal Maintenance Cable

Both ends of BTS terminal maintenance cable are DB9 connectors and are

respectively connected to BTS terminal operation and maintenance port and the

serial port of maintenance terminal (normally portable PC). Figure 2-1 shows the

serial connector. Correspondence of pins on DB9 connectors is shown in Table 2-1.

Chapter 3 Site Function

As shown in Figure 3-1 click [Site0] in the tree structure, and all the function

commands corresponding to [Site0] would be displayed in the right part of the window.

Detailed description of the function commands under [Site0], including operation

procedures as well as the explanation of function commands, is given in the following,

as shown in Figure 3-1.

Figure 3-1 Site operation and maintenance interface

3.1 Site Management Right

I. Function Description

Site management right refers to the right to configure BTS parameters. The BTS

parameters can be configured either via the remote maintenance console at the BSC

side or via the local maintenance console. They cannot be configured via both

consoles at one time. The user should get site management right before performing

operations. Upon initial, the BSC owns the site management right by default. When

the user wants to perform operations via the local maintenance console, he has to get

the site management right beforehand. After operations, he has to release the right.


11/68



3-2

During the process of local maintenance, the priority of the local maintenance console

is higher than that of the remote. No overwrite operations can be performed via the

remote maintenance console. However, before it gets the site management right or

after it releases the right, the local maintenance console has a lower priority andcannot execute any overwrite command successfully. Nevertheless, read commands

can still be executed via it.

Caution:

z The user should get site management right before all modification related

operations such as site maintenance, cell maintenance, BT maintenance, channel

maintenance, radio carrier maintenance and board maintenance. Otherwise, thesystem will prompt "management status is not matched" and the operations

cannot be performed.

z Getting site management right for the local maintenance console may affect the

commands that are being executed via the remote maintenance console.

Therefore, before getting the local site management right, please make sure that

the remote maintenance console is not performing any overwrite operation such

as dynamic data configuration.

II. Operation Procedure

Double click [Site0/Site management right], an interface as shown in Figure 3-2 will

appear. Click , and "Getting site management right successfully" will be

7.4 Loop Test


Channel loop test can be adopted to test the parameters like channel BER and Tx

power of the BT so that the channel quality can be determined. The current BTS3X

can support two kinds of tests: "TRX self-test" and "BIU loop test". TRX self-test is to

test the RF unit. TRX receives the command from the TMU and transmits data to the

RF unit. Then RF unit loops the data back to the TRX. After a certain comparison,

TRX reports the BER report. The operation staff can learn the quality of the current

RF unit link. BIU loop test is to test the link between the TMU and TRX. TRX transmits

data. Then TMU loops the data back to the TRX. TRX calculates and reports the BER.

The operation staff can judge whether the link between the TMU and TRX is normal.

II. Operational Procedure

Double click [Cell/BT/Channel/Change channel administrative state], and in the

pop-up interface, select BIU loop test and set the test time. Click to start the

test. When the test is finished, test report will be displayed in the bottom of the
