4.2.1 TESTING THE PICOBTS
Before disconnecting the physical Ethernet cable, the field technician must make sure that the
cable is labeled in a way that clearly identifies its origin and destination.
• Provide the OMC-R operator with all part, revision and serial numbers for the picoBTS.
4.2.2 RECOVERY TESTS
The OMC-R operator should add the picoBTS to the GUI, configure the Abis to the BSC and
configure the Cell information on the OMC-R or BSC. Then perform the following steps:
1 At the picoBTS, disconnect the physical Ethernet cable.
2 Coordinate with the OMC-R operator to ensure the proper alarms have appeared on the
OMC-R.
3 Reconnect the physical Ethernet cable to the picoBTS.
4 Coordinate with the OMC-R operator to ensure the proper alarms have cleared on the
OMC-R.
4.2.3 TCH TIMESLOT TESTS
1 In this test, the OMC-R operator unlocks individual TCH timeslots and the field
technician places a mobile-to-mobile call over each timeslot using a mobile handset in
debug mode. Refer to the documentation provided by the module handset manufacturer
for the proper procedures.
For each timeslot, the commissioner should verify that:
- The timeslot displayed on the handset corresponds to the timeslot unlocked by the
OMC-R operator.
- A two-way call is completed successfully.
- The call has good audio quality and power, and low interference.
The number of timeslots to be tested will be for two TRXs. Table 4-1 provides the
sequence for two or more TRXs.
