ZXMW NR8250 Alarm and Notification Handling Reference
Sub-code Description
Each subcode represents a timeslot. The former 63 timeslots are used for optical port
1,and the latter 63 timeslots are used for optical port 2.
Effect on the System
All the relay receive signals transmitted on the SDH link may be interrupted.
Possible Causes
1.
The signals sent from the upstream equipment to NR8250 equipment contains the
TU-LOP signal.
2.
The RTUB board that reports the alarm is faulty.
Handling Procedure
1.
Ensure that the signal sent from the upstream equipment to the NR8250 equipment
does not contain the TU-LOP signal.
2.
Check whether the clock configuration is correct.
l
If yes, go to step 3.
l
If no, configure the clock again.
3.
The alarm is caused by RTUB board failure. Replace the board.s
