11.2.1 Alarm Window

Software Release 6.0 has TL1 port-based alarm numbering that identifies an alarmed synchronous
transport signal (STS) by its STS on a port rather than the STS on the optical card. The numbering is
present in the STS alarm TL1 AID. The numbering scheme is described in
Table 11-3
MON Object
(Optical)

STS
1. Port number range varies by card type with a maximum of four.
2. Maximum STS number depends on the rate and size of the STS.

Alarm Window
Action
Allows you to change the display on the Alarms window to show only
alarms that meet a certain severity level, occur in a specified time frame,
and/or reflect specific conditions. For example, you can set the filter so that
only Critical alarms appear on the window.
If you enable the Filter feature by clicking the Filter icon button in one CTC
view, such as node view, it is enabled in the others as well (card view and
network view).
Updates the alarm display. Although CTC displays alarms in real time, the
Synchronize button verifies that CTC and the ONS 15600 agree on current
alarms. This is particularly useful during provisioning or troubleshooting.
Deletes alarms that have been cleared.
If checked, CTC automatically deletes cleared alarms.
