LED Description
Power On when the MultiVoice Gateway power is on.
Fault On in one of two cases: either a hardware self-test is in progress or there is a
hardware failure.
When a hardware self-test is in progress, the LED stays on. If any type of
hardware failure occurs, the LED flashes. If the failure is isolated to a
expansion card, the MultiVoice Gateway might continue to function without
the expansion card.
Data On when calls are active.
Alarm On when there is a WAN alarm or when a trunk is out of service, such as
during line loopback diagnostics.
WAN alarms include Loss of Sync, Red Alarm, Yellow Alarm, and All Ones
(or AIS).
