Airbridge cBTS3612 CDMA Base Station
If the configuration file download fails, the board will not be able
to obtain the correct parameter configuration, and thus the BTS will
not start up properly. Possible causes of file download failure are:
1)
Correct file loading information has not been set up in the
OMC, or the configuration file is not correct;
2)
There is no relevant BTS configuration files in the file
loading directory in the OMC;
3)
The OMC FTP Server has not been started or it is not
running properly;
4)
The specific file path, file attributes and user information
are not configured correctly in the FTP Server.
In such case, we have to check the above possibilities and
eliminate faults one by one (we can perform such operations from
the OMC console). For other possible failure causes and solutions,
we can turn to "2.2 Software Download ".
II.
Board communication link failure
When the board is powered on and the initialization is complete,
it (any board other than the BCKM) will send a configuration request
to the OMU on the BCKM. After receiving correct configuration, it
shall start working. If the ALM and ACT indicators flash at a
frequency of 4Hz, there should be a communication link failure
between the board and the OMU.
1)
If there is only one board (for example: BCIM) generating
alarm, check if that board is plugged and secured properly
and then reset it. If the problem sustains, replace that
board.
