72 UltraWAVE BTS Installation and Commissioning Guide, Release 6.5A
5-1 Pre On-Line Commissioning Requirements
Before on-line commissioning begins, the field technician or the OMC operator must verify that:
• The BSC or BS Plus, and the WXC or MSC are fully commissioned, in service and connected
to each other and to the BTS.
• The OMC is in service and connected to the BSC via the MSC as defined in the interWAVE
Network Implementation Manual.
• The database questionnaire is completed, with all necessary BTS parameters listed, as
defined in the interWAVE Network Implementation Manual
.
• The OMC operator has successfully created and configured the BTS object on the OMC and
downloaded this information to the BTS.
• The RF frequencies are cleared to transmit.
• The E1 or T1 connection between the BTS and the BSC has been commissioned.
• The BSC-BTS E1 or T1 link is properly certified. Note that the certification should state
length of testing and BER results.
• The HLR subscriber data has been entered into the HLR using the Subscriber Management
GUI, as described in the interWAVE Subscriber Management Guide
. In particular, the HLR
must be configured to support the SIM cards of the mobiles used by the field technician.
• The Abis link and its child objects are locked at the OMC.
Once the E1 or T1 link has been properly connected to the BTS E1 or T1
trunk card, both port alarm LEDs for the connected port should turn off.
If one or both LEDs remain lit, signifies an E1 or T1 link problem related
to either a faulty connector or the E1 or T1 link itself. Refer to the
interWAVE Field Maintenance Guide
for additional information.
It is the operator's responsibility to verify that all BSC-BTS E1 or T1 Abis
links are ordered, installed and certified by the local telephone provider.
Certification should include a bit error ratio/rate test of at least
20 minutes on the Abis interface, with a BER of 10
-8
or better.
