2.5.5 Service Effect
Service-Affecting (SA) alarms—those that interrupt service—might be Critical (CR) or Major (MJ)
severity alarms. Service-Affecting (SA) alarms indicate service is affected.
Non-Service-Affecting (NSA) alarms always have a Minor (MN), Not Alarmed (NA), or Not
Reported (NR) severity.
2.5.6 States
The Alarms and History tab State (ST) columns indicate the disposition of alarms and conditions as
follows:
•
A raised (R) event is one that is active.
•
A cleared (C) event is one that is no longer active.
•
A transient (T) event is one that is automatically raised and cleared in CTC during system changes
such as user login, logout, loss of connection to node view, etc. Transient events do not require user
action. These are listed in
Chapter 3, “Transient Conditions.”
