13.1 Overview
CTC detects and reports SDH alarms generated by the Cisco ONS 15454 SDH and the larger SDH
network. You can use CTC to monitor and manage alarms at the card, node, or network level. Default
alarm severities conform to the ITU-T G.783 standard, but you can set alarm severities in customized
alarm profiles or suppress CTC alarm reporting. For a detailed description of the standard ITU-T
categories employed by Optical Networking System (ONS) nodes, refer to the Cisco ONS 15454 SDH
Troubleshooting Guide.
Note ONS 15454 SDH alarms can also be monitored and managed through a network management system
(NMS).
13.2 Documenting Existing Provisioning
You can use the File > Print or File > Export options to print or export CTC provisioning information
for record keeping or troubleshooting. The functions can be performed in card, node, or network views.
The File > Print function sends the data to a local or network printer. File > Export exports the data to a
file where it can be imported into other computer applications, such as spreadsheets and database
management programs.
