Alarms


The Alarms tab lists current alarms (CR, MJ, MN) for the Cisco ONS network (network view), node (node view) or card (card view) and updates them in real time. The Alarms tab shows alarms in compliance with Telcordia GR-253. This means that if a network problem causes two alarms, such as loss of frame (LOF) and loss of signal (LOS), CTC shows only the LOS alarm in this window because it supersedes and replaces the LOF.

Tip: In network view, double-click an alarm to display the node or card where the alarm occurred. In node view, double-click an alarm to display the card where the alarm occurred.
