Chapter 2 Alarm Troubleshooting

XTC Line Alarms

Procedure: Clear the UNEQ-V Alarm

Step 1 Complete the “Clear the UNEQ-P Alarm” procedure on page 2-122.

Step 2 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).

2.6.188 WKSWPR

Not Alarmed (NA), Non-Service Affecting (NSA)

The Working Switched To Protection (WKSWPR) condition occurs when a line experiences an LOS (OC-N) alarm (see page 2-84), an SF condition (see page 2-106), or an SD condition (see page 2-104).

Procedure: Clear the WKSWPR Condition

Step 1 Complete the “Clear the LOF (OC-N) Alarm” procedure on page 2-80.

Step 2 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).

2.6.189 WTR

Not Alarmed (NA), Non-Service Affecting (NSA)

The Wait To Restore (WTR) condition occurs when a WKSWPR condition (see page 2-124)is raised the wait-to-restore time has not expired, meaning the active protect path cannot revert to the working path. The condition clears when the timer expires and traffic is switched back to the working path.

Note WTR is an informational condition. It does not require troubleshooting.

2.7 XTC Line Alarms

The XTC-28-3 card provides three choices of line types: ESF, D4, or Unframed. The choice of framing format determines the line alarms that the XTC-28-3 card reports. The following table lists the line alarms reported under each format.

The choice of framing format does not affect the reporting of STS alarms. Regardless of format, the XTC-14 card reports the same STS alarms as the standard XTC-28-3 card does.
