AIS can be ignored or set to raise an alarm, regenerate AIS and send a backward alarm
where possible as described in
Table 6-42
.
Ignore
Ignore any AIS indication.
Prompt
When AIS is detected, raise an alarm, regenerate the AIS indication and
send a backward alarm to the upstream equipment.

6.2.10.3 Local/Remote Eb/No Alarm Threshold
Range:
0dB to 99.0dB; step size: 0.1dB
Description:
These set the Eb/No thresholds below which a deferred alarm will be
generated for the local (i.e. received carrier) and remote (i.e. transmitted
carrier) Eb/No values respectively.
Table 6-43 Local/Remote Eb/No Alarm Threshold
6.2.10.4 Buffer Slip Alarm Threshold
Range:
0 hours to 9999 hours; step size: 1 hour
Description:
Sets the threshold period for consecutive buffer slips above which a
deferred alarm is generated. A setting of 0 (zero) disables this alarm.
Table 6-44 Buffer Slip Alarm Threshold
6.2.10.5 BUC DC Current Alarm
Even when there is no communications path between the BUC and modem, it is still
possible for the modem to monitor the BUC for under/over current and over temperature
conditions that cause the BUC to shut down.
Table 6-45
describes how to set the BUC
minimum and maximum DC current levels outside of which a BUC DC current alarm will
be raised if
BUC DC alarm enable
is set.
