1. Check the error log via
display errors
for other SNI circuit packs
with the 257 SNI-BD error. If other SNI circuit packs in the same
switch node carrier have error 257, then replace the active SNC.
2. Replace this SNI.
3. Replace the active SNC in the same switch node carrier.
4. Enter
display errors
and if this error is still in the error log, follow
normal escalation procedures.
f. This error indicates that the SNI cannot communicate with the DS1C.
1. Perform the Fiber Fault Isolation Procedure described in Chapter 5.
g. This error indicates a failure communicating synchronization control data
with the active SNC.
Look at all of the SNI-BD errors in the log via
display errors
and
display
alarms
to determine whether to follow procedure 1 or procedure 2. See
the table below which lists pairs of SNIs that are considered to be
adjacent. Use Procedure 2 if either of the following two conditions is
present:
— At least one pair of adjacent SNIs in this carrier has Error 769 with
an off-board alarm logged against both SNIs in the pair.
— The active SNC in this carrier has error 257.
If neither of the above is true, follow Procedure 1.
Procedure 1 (suspect TPN link or clock generation out of lock
problem):
1. Enter display alarms and display errors and follow the
procedures for any on-board SNI-BD error and alarm entries.
2. If more than one SNI circuit pack in the same switch node carrier
has SNI-BD error 769 with an off board alarm, replace the active
SNC in the same carrier.
3. Replace this SNI.
