installation, using an OMT. Subsequently any of these parameters may
be modified using an OMT.
The RBS supervises each configuration auxiliary fault. An auxiliary
fault is filtered, that is, must remain in a new state a fixed period of
time (approximately 3 seconds) before the BSC is notified.
fault is filtered, that is, must remain in a new state a fixed period of
time (approximately 3 seconds) before the BSC is notified.
The detected fault is reported by sending of a fault report for the
concerned MO(s) over the Abis interface according to the "Diagnostic
and Fault Handling" function. Which MO class and instance to report
the fault on, is derived from the ARAE supervision parameters, receiver
diversity configuration and radio configuration.

The BSC will then take the affected MO(s) out of operation, if
appropriate.
