Change Alarm Thresholds
1. In the main menu, click Status.
2. Click Alarm Monitor.
3. Click the up and down arrows
to set the alarm threshold.
This sets the amount of time a
minor alarm exists before becoming
a major alarm.
For CDMA inputs, this also sets the
amount of time from the beginning
of bridging mode to escalation to a
minor alarm. The system stays in
bridging mode for 25 percent of the
programmed threshold. For
example, if the threshold is
48 hours, and the CDMA input is
lost, the system stays in bridging
mode for 12 hours (25 percent of
48 hours), then escalates to a minor
alarm. If CDMA input loss continues
for 48 hours from the start of
bridging mode, the system escalates
to a major alarm.
Caution:
Do not set the threshold to
less than 12 hours — spurious
alarms may result.
Notes:
a. The recommended setting is
48 hours (factory setting).
b. The threshold setting only
affects span and remote
oscillator inputs if they are both
provisioned and ensembled.
