Select the Affected Circuits Option for an Alarm
When the user selects the Select Affected Circuits option, the Circuits window opens to show the circuits
that are affected by the alarm.
11.2.3 Conditions Window
The Conditions window displays retrieved fault conditions. A condition is a fault or status detected by
ONS 15600 SDH hardware or software. When a condition occurs and continues for a minimum period,
CTC raises a condition, which is a flag showing that this particular condition currently exists on the
ONS 15600 SDH.
The Conditions window shows all conditions that occur, including those that are superseded by alarms.
For instance, if a network problem causes two alarms, such as LOF and LOS, CTC shows both the LOF
and LOS conditions in this window. Having all conditions visible can be helpful when troubleshooting
the ONS 15600 SDH. If you want to retrieve conditions that obey a root-cause hierarchy (that is, LOS
supersedes and replaces LOF), you can exclude the same root causes.
Fault conditions include reported alarms and Not Reported or Not Alarmed conditions. Refer to the
trouble notifications information in the
Cisco ONS 15600 SDH Troubleshooting Guide
“Alarm
Troubleshooting” chapter for more information about alarm and condition classifications.
