Alarm messages
Each alarm can be assigned one of the following reporting states:
Alarm severity
Reported
Not Reported
Please note that changing the alarm reporting state does not affect the display of
currently present and history alarms. Especially the display of already present alarms
cannot be removed if their reporting state is changed from "Reported" to "Not
Reported".
Local indications
Local indications are indications directly at the network element, typically via
light-emitting diodes (LEDs), especially via the red fault LED on the unit.
Please note that the local indications via the red fault LED are controlled by defects,
not alarms.
