???????Acceptance Test for MCT BTS (Version 2)

Acceptance Test of BTS Contains Three Parts :

1- Visual Check of Mechanicals and Electrical parts

2- Off Line Tests

3- Online Tests

1) Visual check of Mechanics and Electrics :

- Antenna panel and Connected Cables

OK?

- E1 Panel and Connected Cables

OK?

- Correct Location of boards and passive modules

(SRU,OMT , HUB, DMU, TRX, PAU, CU , FU )

This item depends on BTS Configuration

OK?

- Cabling of inter-shelf Connections (flat cables)

OK?

- Cabling of Ethernet(HUB, OMT and MMI interface) OK?

- Grounding check

OK?

84


????????????????????????V-2BTS

- RF Cabling check

OK?

-Power Connections (48V)

OK?

- Fuse checking

OK?

- Jumper setting for shelf number

OK?

TRX shelf # 0

TRX shelf # 1

TRX shelf # 2

OMT has no Jumper Setting

-External Alarm Connection OK?

85


????????????????????????V-2BTS

2) Off Line Tests

Before BTS power on , it is required to prepare MMI computer and install

the related software

This computer must have a network card.

This part includes three tests groups.

a) Rack Preparing

b) Boards test

c) Power Amplifier tests

a) Rack Preparing

After 48v(dc) connection and cabling check

OMT shall be Powered on.

-OMT LED Status :

ok? OMT

? green? green? green? red

PowerEthernet

86


????????????????????????V-2BTS

After OMT power on , Power and Active LED , should be green and after

connecting of Ethernet cable between OMT and HUB , Ethernet LED

must be green.

- SRU and TRX LED Status

ok?

After turning on the Fuses of TRX shelves the TRX status LED should

become green .

87


????????????????????????V-2BTS

Power and Active LED of SRU and TRXs should be green. Fault LED

must be Off.

-PAU LED status

OK?

- AP and RP LEDs must be powered on.

OK?

- MMI Connection check

OK?

After Running of MMI software , MMI must be connected to OMT (Data link

Establishing)

OK?

- Software Download to OMT

Last Version of BTS Software must be downloaded. It may take several

minutes .

- OMT Restart

OK?

88


????????????????????????V-2BTS

After OMT reset, software will be downloaded to boards and automatically

SRUs will be restarted .

- Site configuration settings

It is depended on designated configuration of site (1+1+1, 2+2+2 , )

MCT proposes a default setting for the configurations to optimize the

cabling , but user may change this cabling and configure whatever he wants.

Now BTS must be restarted .

2-b)Boards test- Fault LED of E1 blinking

OK?

If site is configured N0-chain , with loop back of Main E1 connectors

blinking will be disappeared. But if site is configured chain, the chain E1

connectors must be looped for disappearing the E1 blinking .

- SRU-OMT Loop back check (for all boards)

OK?

This test is performed from MMI menu. Get sure that main E1 connectors

to be looped.

BER=0 is the condition that passes this test.

89

????????????????????????V-2BTS

-SRU-TRX Loopback check (for all boards)

- main

OK?

- diversity

OK?

Before this test TRX output must be connected to main or diversity inputs.

BER

91


????????????????????????V-2BTS

3) Online tests

For these tests MA10 or BSC is necessary.

-Call Originating Establish

OK?

-Call Terminating Establish

OK?

-DPC check (Downlink power control)

OK?

- Hanover test (for outdoor sites)

OK?

-DTX check

OK?
