14.3 Alarm Information

The ONS 15454 has a one-button update for some commonly viewed alarm counts. If you press the Slot
button once and then wait eight seconds, the display automatically changes from a slot alarm count to a
slot alarm summary. If you press the Port button to toggle to port-level display, you can use the Port
button to toggle to a specific slot and to view each port's port-level alarm count.

14.3 Alarm Information
You can use the Alarms tab to view card, node, or network-level alarms. The Alarms window shows
alarms in conformance 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 only shows the LOS alarm in this window
because it supersedes LOF. (The LOF alarm can still be retrieved in the Conditions window.)
The Path Width column in the Alarms and Conditions tabs expands upon alarmed object information
contained in the access identifier (AID) string (such as "STS-4-1-3") by giving the number of STSs
contained in the alarmed path. For example, the Path Width will tell you whether a critical alarm applies
to an STS1 or an STS48c. The column reports the width as a 1, 3, 6, 12, 48, etc. as appropriate,
understood to be "STS-N."
