23.1 Overview

CTC detects and reports alarms generated by the Cisco ONS 15454 and the larger network. You can use
CTC to monitor and manage alarms at the card, node, or network level. Default alarm severities conform
to the Telcordia GR-253-CORE standard, but you can set alarm severities in customized alarm profiles
or suppress CTC alarm reporting. For a detailed description of the standard Telcordia categories
employed by Optical Networking System (ONS) nodes, refer to the Cisco ONS 15454 DWDM
Troubleshooting Guide, the Cisco ONS 15454 Troubleshooting Guide, or the Cisco ONS 15454 SDH
Troubleshooting Guide.
ONS 15454 alarms can also be monitored and managed through Transaction Language One (TL1) or a
Note
network management system (NMS).
