6-8 Handling Alarms FCD-E1
This manual uses the term ON-state alarm. An ON-state alarm is either an
ON-type alarm or an ON/OFF-type alarm when its alarm condition is still present.
When an ON/OFF-type alarm changes its state from ON to OFF, it is not removed
from the alarm buffer. Moreover, a new entry of this alarm is added to the alarm
buffer. This feature enables you to view the alarm history on the terminal using the
DSP ALM command. A typical display looks like this:
ALARM 21 SIGNAL LOSS SL ON 01:42:11
ALARM 21 SIGNAL LOSS ML ON 01:45:14
Alarm Messages
Table 6-3 presents in alphabetical order the alarm messages displayed on the
FCD-E1 LCD and control terminal, and lists the actions required to correct the
alarm condition.
