SONET/SDH Alarms
The ML-Series cards report SONET/SDH alarms under both Cisco IOS and CTC/TL1. A number of path
alarms are reported in the Cisco IOS console. Configuring Cisco IOS console alarm reporting has no
effect on CTC alarm reporting. The
the alarms reported to the Cisco IOS console.
CTC/TL1 has sophisticated SONET/SDH alarm reporting capabilities. As a card in the ONS node, the
ML-Series card reports alarms to CTC/TL-1 like any other ONS card. On the ONS 15454 SONET, the
ML-Series card reports Telcordia GR-253 SONET alarms in the Alarms panel of CTC. For more
information on alarms and alarm definitions, refer to the "Alarm Troubleshooting" chapter of the
Cisco ONS 15454 Troubleshooting Guide or the Cisco ONS 15454 SDH Troubleshooting Guide.
