11 Troubleshooting and fault reporting
In the case of a failure in the commissioning procedure, check if there is a
corresponding alarm in the Alarms window in Nokia BTS Manager (see the BTS
Alarm Descriptions document in the Nokia MetroSite EDGE Base Station SW
release binder). Also, you may check the cause of a failure from the
commissioning report.
The commissioning procedure may fail for the following reasons:
• The Abis cables are not properly connected (the transmission unit LED will
not show green).
• The pre-configuration failed at the BSC. For example, the BCF and TRX
objects were not created.
• PCM time-slot allocations are incorrect. The parameters at the BSC and on
the site are not the same. Run ‘Undo Commissioning’ and redo
commissioning with the correct parameters.
• The PCM port is not activated at the BSC.
• The transmission path is incorrectly configured. Check cross-connections.
• The CRC and/or interface mode settings for the E1/T1 card are incorrect.
In BTS Manager, choose LIF SETTINGS on the TRANSMISSION menu,
and check that the ‘CRC in Use’ and ‘Interface Mode’ settings are correct
for the interface.
Before starting to re-commission the BTS, first run the ‘Undo Commissioning’
procedure. If the Commissioning Wizard has stopped, click CANCEL to abort the
commissioning procedure.
Report all damages, failures or faults to Nokia using the Failure Report Form
provided by Customer Services (CS).
