New Features and Functionality

If alarms are suppressed, they do not appear on the CTC Alarm screen. On the History and Conditions screens a message states that the alarm or alarms are suppressed. The node sends out autonomous messages to clear any raised alarms. When alarm suppression is turned off, the node sends out autonomous messages to raise any suppressed alarms.

Alarm Profiles

The ONS 15327 includes an alarm profile feature. This allows you to change the default alarm severities (for example, change an alarm severity from minor to major) and apply the new severities at the card, port, node, or network level.

Default Reporting of AIS and RFI

To improve compliance with Telcordia GR-253, Release 3.0.x reports AIS and RFI failures as not alarmed (NA). These will appear on the conditions pane only. Users can change this default with the Alarm Profile feature described in the “Alarm Profiles” section on page 16 .

Every alarm has a default profile. To create a new profile, clone the default profile in CTC, rename it, and choose the severity settings for the new profile. Activating and changing profiles are simple procedures in CTC.
