8.2 Bringing the RBS into Service

This section describes how to bring the RBS into service.

Note: The BSC operator can bring the MOs into service and deblock them

even when the RBS is in remote mode. (The RBS then responds

directly to the BSC operator.)

1. Set the RBS in local mode by pressing the Local/remote button on the IXU.

2. Wait until the Local indicator has a steady yellow light, indicating that the

RBS is in Local Mode.

3. Wait for the BSC operator to bring the MOs on each TRX into service

logically and deblock them.

4. Press the Local/Remote button on the IXU. The Local indicator will start

flashing.
