???????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
MobileCommunicationsTechnologies
????????????????????????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?

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.

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

- 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
MobileCommunicationsTechnologies
????????????????????????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.
