When parameter 1=0x13 and parameter 2=0x02, parameter 3 takes the following values:

• 0x01 indicates inter-board communication channel 1 failure.
• 0x02 indicates that the FE rate channel (belonging to channel 2) of inter-board communication has failed.

• bit[2]=1 indicates that APS (Automatic Protection Switching) logic lookup table return failure.
• bit[3]=1 indicates that the APS logic load state detection has failed.
• bit[5]=1 indicates that the control logic sends the cross-board master and backup status of the APS logic through the hardware connection line, which is inconsistent with the status actually detected by the control logic.
• bit[6]=1 indicates that the APS logic phase-locked loop is out of lock.

For the master board, if parameter 1=0xFF, parameter 4 represents a different meaning.

For Video (VST4) single board, represents the fault type.

A bit of 1 indicates that the alarm exists, and a bit of 0 indicates that the alarm does not exist. Multiple bits can be in effect at the same time.

Parameter 5

For the master board, if parameter 1 = 0xFF, parameter 5 represents a different meaning.

A bit of 1 indicates that the alarm exists, and a bit of 0 indicates that the alarm does not exist. Multiple bits can be in effect at the same time.

Remarks

For example, if the parameter is 0x04 and converted to binary as 100, it means bit[2]=1, bit[1]=0, bit[0]=0 respectively.
