Configuring the BTS3012 S12/12/12

This describes how to configure the S12/12/12 for the BTS3012 by using the QTRU.

Scenario	BSC initial configuration and BSC capacity expansion
Mandatory/Optional	Optional. The BTS3012 S12/12/12 is configured when necessary.

NOTE:

The procedure for configuring the S12/12/12 for the BTS in TDM transmission mode is the same as that for configuring the S12/12/12 for the BTS in HDLC/HUB transmission mode.

On one QTRU, one physical TRX is bounded with six logical TRXs. To ensure bandwidth, you are advised to add site chains.

Prerequisites

Procedure

1. Start the wizard for adding a BTS.
   • When adding a BTS for the first time, you can start the wizard for adding a BTS only on the GEIUB/GOIUB in the GMPS or GEPS. On the BSC6000 Local Maintenance Terminal, right-click a GEIUB in the GMPS.
   • If a BTS already exists, you can add a cascaded BTS under this BTS. On the Management Tree tab page, right-click a BTS.
