Alarm Severity
Alarm Severity
The DWDM system uses Telcordia-devised standard severities for alarms and conditions: Critical (CR), Major
(MJ), Minor (MN), Not Alarmed (NA), and Not Reported (NR). These are described below:
• Critical (CR) alarm—Indicates severe, service-affecting trouble that needs immediate correction.
• Major (MJ) alarm—Indicates a serious alarm, but the trouble has less impact on the network.
• Minor (MN) condition—Indicates alarms that do not affect service.
• Not Alarmed (NA) condition—Indicates conditions that are information indicators.
• Not Reported (NR) condition—Indicates a condition that occurs as a secondary result of another event.
