13.4 Viewing Alarms
In the card-, node-, or network-level CTC view, click the Alarms tab to display the alarms for that card,
node, or network. The Alarms window shows alarms in conformance with ITU-T G.783. 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 the LOF and replaces it.
The Path Width column in the Alarms and Conditions tabs expands upon alarmed object information
contained in the access identifier string (such as “VC4-6-1-6”) by giving t he number of VC-4s contained
in the alarmed path. For example, the Path Width will tell you whether a Critical alarm applies to a VC-4
(where the column will show 1) or a VC-12 (where the column will show 3). If the path contains a
smaller circuit size than VC-4, the column is empty.
Table13-1 lists the column headings and the information recorded in each column.
