UltraWAVE Micro BTS Installation and Commissioning Guide, Version B 113
Pre On-Line Commissioning Requirements
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 Micro BTS, and the MSC are fully commissioned, in service and
connected to each other.
 The OMC is in service and connected to the Micro BTS via the MSC as defined
in the GSM Network Implementation Manual
.
 The database questionnaire is completed, with all necessary Micro BTS
parameters listed, as defined in the GSM Network Implementation Manual
.
 The OMC operator has successfully created and configured the Micro BTS
object on the OMC and downloaded this information to the Micro BTS. Refer to
the procedures described in the UltraVIEW OMC Configuration Guide
.
 The RF frequencies are cleared to transmit.
 The MSC-Micro BTS E1 or T1 link is properly certified. Note that the certifica-
tion 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 GSM Subscriber Management Guide
. In
particular, the HLR must be configured to support the SIM cards of the
mobiles used by the field technician.
Once the E1 or T1 link has been properly connected to the Micro
BTS E1 or T1 trunk card, both port alarm LEDs for the
connected port should turn off. If one or both LEDs remain
illuminated, an E1 or T1 link problem exists related to either a
faulty connector or the E1 or T1 link itself. Refer to the GSM
Field Maintenance Guide for additional information.
It is the operator's responsibility to verify that all Micro 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.
