Bts Channel Processing Module (Bcpm) - Huawei Airbridge CBTS3612-800 User Manual

User Manual
Airbridge cBTS3612-450 12-carrier CDMA Base Station
II. The Abis signaling link cannot be established between the base station
and BSC
The Main Control (MC) unit on the BCKM is responsible for establishing the Abis
signaling link with the BSC. If this link fails to be established, please refer to "3.5 Abis
Signaling Link Fault".
III. The base station clock does not work normally
The clock unit (CLK) on the BCKM is responsible for receiving and processing the
GPS or GLONASS clock signals. Possible clock unit faults are as follows: clock
module hardware faults, satellite antenna feeder system fault, reference clock source
driving fault, clock reference driver source error and main clock lose lock.
When the above-mentioned clock faults occur, first check the satellite antenna feeder
system and then check the configurations of the clock reference source. If it does not
work, please reset the BCKM. If the fault still exists, this BCKM needs replacing.
IV. Other faults of the BCKM board
The main cabinet PSU fault and base band frame fan module fault are also reported
to the BCKM and listed with other faults. If it is the base band frame fan module fault,
it is necessary to replace the fan module. If it is the main cabinet PSU fault, handle it
as described in "6.10 Power Supply Unit (PSU)".

6.5.2 Fault Analysis and Location
I. System clock error
To any system clock error, please handle it as described in "6.4 BTS Control &
Clock Module (BCKM)".
II. Gigabit Ethernet link reverse data error
To any Gigabit Ethernet link reverse data error, it is necessary to check whether the
BRDM connected via the backplane with this BCPM works normally. Please handle it
as described in "6.6 BTS Resource Distribution Module (BRDM)".
III. FPGA status error
To any FPGA status error, it is necessary to reload the software of FPGA. If the fault
still exists, it is the related board hardware being faulty and the board needs
replacing.
