Alarms
(ALARM BUFFER)
FOMi-E1/T1 contains a buffer which stores the system alarms. When
alarms are stored in the alarm buffer, the ERR LED indicator is on. Once
the alarm buffer is cleared, the ERR LED turns off.
The cause of the problem is displayed in the Menu Option field. If the
failure has more than one cause, scroll through the field to view the other
causes.
The ERR LED might blink with no relation to the ALARM BUFFER when an
error is detected during a BER test. The following table lists all possible
FOMi-E1/T1 alarms.
