14.1 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.733 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).
14.2 LCD Alarm Counts
You can view node, slot, or port-level alarm counts and summaries using the buttons on the
ONS 15454 SDH LCD panel. The Slot and Port buttons toggle between display types; the Slot button
toggles between node display and slot display, and the Port button toggles between slot and port views.
Pressing the Status button after you choose the display mode changes the display from alarm count to
alarm summary.
