2.3 Replacement of BTS Control Interface Module (BCIM)

I. Note
1) The replacement of a BCIM will interrupt all services transmitted via the BCIM.
2)
BCIM should be anti-static, therefore operations should be made strictly based
on operation procedures. That is to say, wear an anti-static wrist strap and
gloves and make the grounding terminal well grounded to prevent any static
electricity damaging the board.
II. Replacement Details
1)
View the BCIM alarm and block corresponding BTRM
Connect a portable computer with the local-end maintenance software with the
Ethernet interface of a base station BCKM and switch on Telnet to log on to the base
station. Then, view and record the fault type and software/hardware versions of
BCIM.
For a BTRM which will interrupt services, execute the command of sector carrier
blocking or shut off its power.
2)
Unplug BCIM
Pull the BCIM out of the slot.
3)
Plug a new BCIM
Check and find that the impedance of BCIM matches DIP switch jumper J6 and
S2~S9. Then, plug the new BCIM into a corresponding slot and wait to successfully
reestablish links with BSC.
4)
Change the management state of the blocked BTRM
Unblock the blocked BTRM.
If you turn off the power switch of a corresponding BTRM in advance instead of
blocking the BTRM, then turn on the corresponding switch in this step.
5)
Test
Conduct a conversation test with a mobile station and view whether BCIM software
version is the one to run normally.
6)
After replacement
If the new BCIM has passed all tests, related alarms disappeared and corresponding
recovered alarms occurred, it shows that the replacement of a BCIM is completed.

2.4 Replacement of BTS Channel Process Module (BCPM)

I. Note
1)
The replacement of a BCPM will interrupt the current service processed by the
BCPM.
2)
BCPM should be anti-static, therefore operations should be made strictly based
on operation procedures. That is to say, wear an anti-static wrist strap and
gloves and make the grounding terminal well grounded to prevent any static
electricity damaging the board.
