Viewing Alarms
In network view, CTC identifies VC high-order path and VC low-order path alarm objects using a
TL1-type AID, as shown in Table 10-3.
10.2.1 Viewing Alarms With Each Node’s Time Zone
By default, alarms and conditions are displayed with the time stamp of the CTC workstation where you
are viewing them. But you can set the node to report alarms (and conditions) using the time zone where
the node is located by clicking Edit > Preferences, and clicking the Display Events Using Each Node’s
Timezone check box.
Magenta Raised Not-Alarmed (NA) condition
Blue Raised Not-Reported (NR) condition
White Cleared (C) alarm or condition
