14.3 Alarm Information
The ONS 15454 SDH 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. Figure 14-1
shows the LCD panel layout.

14.3 Alarm Information
In the card, node, or network 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.733. 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 string (such as “VC4-6-1-6”) by giving the 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.
Table 14-1 lists the column headings and the information recorded in each column.
