Climate Protection
Fault class There are two possible severity
classications
Antenna instance number Denes the physical antenna
Each of these parameters is initially dened manually on RBS
installation, using an OMT. Subsequently any of these parameters may
be modied using an OMT.
The RBS supervises each conguration auxiliary fault. An auxiliary
fault is ltered, that is, must remain in a new state a xed period of
time (approximately 3 seconds) before the BSC is notied.
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 conguration and radio conguration.
The BSC will then take the affected MO(s) out of operation, if
appropriate.
44.4 Operational Conditions
44.4.1 Operation and Maintenance
Maintenance functions related to auxiliary faults are described within
the context of Operation and Maintenance Terminal.
The visual indicators relevant to auxiliary faults are described are
described within the context of Operation and Maintenance Support.
44.4.2 Capabilities
The alarm inlets are used both for external alarms and supervision of
ARAE faults.
The capabilities of the different Radio Base Stations are shown in the
table below:
