5 Troubleshooting and fault reporting
In the case of a failure in the commissioning procedure, an alarm will appear in
the alarm window (refer to the BTS Alarm descriptions document in the SW
release binder). Also, you may check the cause of a failure from the
commissioning report and the diagnostic report.
The commissioning procedure may fail, e.g. when:
• the Abis cables are not properly connected (then the transmission unit LED
is not green)
• the pre-configuration failed at the BSC, e.g. the BCF and TRX objects were
not created
• the oven oscillator has not yet warmed up (then the BCF remains in the
‘Configuring’ state)
• the TRXs are not unlocked at the BSC (then the TRXs do not enter the
‘Supervisory’ state)
• the PCM port is not activated at the BSC.
Before starting to re-commission the BTS, first run the Undo Commissioning
procedure.
All damages, failures or faults must be reported to Nokia using the Failure Report
Form provided by the Customer Services (CS).
