Each fault point is associated with one of the following default severity types.
Table 1: Fault Severity
A failure that is likely causing serious loss or interruption of traffic.
A failure that could potentially lead to loss or interruption of traffic.
A failure that does not significantly affect traffic.
A fault that results in a standing condition, not an alarm.
A minor, major, or critical alarm not reported, because it is being masked by another alarm.
Faults with NR severity always behave as non-alarmed conditions. Notifications for raise and clear events are never generated for these faults, and active occurrences can be discovered only when the active conditions list is polled.
