Events displayed
Alarms and autonomous events are the only events visible to the user on the CIT or
SC interface. Alarms are part of a category of user’s warnings, also referred to as
events. Therefore an event can be an alarm or some other type of notification, other
than an alarm. Events encompass the following two classes:
• Alarm;
• Autonomous Event.
Alarm
A maintenance warning which indicates a fault on a maintenance entity because the
entity has experienced a specific failure. Typically, alarms can be divided into NE
alarms and station alarms. A severity level can be assigned to each alarm.
Autonomous events
Any kind of defect, failure, or alarm on Network Elements, lines or paths. An
autonomous event may, or may not, have any impact on service. They do not
necessarily and obligatorily lead to an alarm, but alarms may be caused by an event.
