3.6 BTS Resource Distribution Module (BRDM)

3.6.1 Fault Description

I.
FPGA status error
II.
The bottom-layer communication link between the BRDM
and BTRM is broken
III.
Abnormal clock signal
IV.
Hardware failure of the board

3.6.2 Troubleshooting

I.
FPGA status error
For FPGA status errors, reload the FPGA software first. If the
problem sustains, it should be the hardware problem in the board.
Replace that faulty board.
II.
The bottom-layer communication link between the BRDM
and BTRM is broken
If the bottom-layer communication link between the BRDM and
BTRM is broken, it may be because the bit error rate (BER) in the
communication link is too high, or the board is not working properly.
