2 If connected to centralized fault management equipment (optional),
transmits an alarm indication to the fault manager to alert the system
administrator of the failure.
3 A local visual indication is active due to this failure.
4 Invokes a failure announcement for the 4-wire link because control
signaling on the V.24 link drives activity on the 4-wire link. A 4-wire
link cannot be used when the V.24 link is down.
Recovery of the link failure results in a similar set of actions to indicate
that the failure event cleared.
NOTICE: A failure of the transport line or a failure of the oppos-
ing host on the wireline link both appear to the base radio as a
link failure. The base radio cannot distinguish between these
two cases.
In the event the base radio detects a hardware issue with the transceiver
option card, when used for analog and mixed mode operation, it:
1 Logs an occurrence of the failure in the local event log. This log is re-
trievable through the configuration interface.
2 If connected to centralized fault management equipment (optional),
transmits an alarm indication to the fault manager to alert the system
administrator of the failure. The alarm is associated with the base ra-
dio control module.
3 A local visual indication is active due to this failure.
In the event the fan assembly malfunctions, the base radio:
1 Logs an occurrence of the failure in the local event log. This log is re-
trievable through the configuration interface.
2 If connected to centralized fault management equipment (optional),
transmits an alarm indication of "warning" severity to the fault manag-
er to alert the system administrator of the failure. The alarm is associ-
ated with the base radio control module.
3 Provides a local visual indication associated with the failure.
4 If the base radio detects the maximum operable temperature has
been exceeded, it transitions to a critical malfunction state, logs the
state change, and generates a fault indication if connected to the
UEM.
The following conditions must be met to obtain a power consumption of
less than or equal to 35 W:
•
DC source only
•
Speaker turned OFF (if equipped with a transceiver option card)
•
No activation of Aux Out Relays (if equipped with a transceiver option
card)
•
No 29 V AUX loads. For example, active draws by a site controller
•
CSS configured for applications not requiring receiver diversity
•
CSS Fan Holdover configured to "short" (length of time the fan stays
ON after transmission)
