44 Handling of Auxiliary Equipment
A number of customer dened, antenna related auxiliary equipment can
be supervised by the RBS. The raising of an auxiliary fault is, after
analysis in the RBS, reported to the BSC. Depending on what severity
the operator has dened for the fault, the concerned MO could be taken
out of operation.

ARAE Antenna Related Auxiliary Equipment.
Examples are boosters and active antennas.
Auxiliary Faults Detected by supervision of auxiliary
equipment.
External Alarms Binary alarms that are reported over Abis
transparently through the RBS. An
example is re alarm.
Alarm Inlet The binary inlet to which the supervised
equipment is connected. Used for both
Auxiliary Faults and External Alarms.
Alarm Setup The parameter denition for the alarm
inlets, which is set by OMT.
44.3 Function
The following ARAE supervision parameters are associated with each
auxiliary fault:
Inlet number 116. Denes which inlet the Auxiliary
Equipment is connected to.
Inlet usage "Auxiliary Fault", "External Alarm" or
"Not dened". The default alarm setup is
that all alarm inlets are Not Dened,
which means that they have no effect on
fault reports for auxiliary equipment,
external alarms or fault indicators.
Fault activation criteria Either closing or breaking the sensor loop.
If inlet usage is set as "Auxiliary Fault", the following fault information
parameters are also set:
