Configuring the BTS3012 S6/6/6 (DTRU and QTRU)

This describes how to configure the S6/6/6 for the BTS3012 by using both the DTRU and the QTRU.

Scenario	BSC initial configuration and BSC capacity expansion
Mandatory/Optional	Optional. The BTS3012 S6/6/6 is configured if required.

NOTE:

The procedure for configuring the S6/6/6 for the BTS in TDM transmission mode is the same as that for configuring the S6/12/12 for the BTS in HDLC/HUB transmission mode.

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

The BTS3012 S6/6/6 is configured with four logical TRXs bound on the QTRU and two logical TRXs bound on the DTRU.

Prerequisites

Procedure

1. Start the wizard for adding a BTS.

    • When you select EDGE Support, GPRS Support is selected automatically if the GPRS function is not enabled. You also need to select a PCU from the PCU drop-down list.
    • For frequencies on the same QTRU, the absolute bandwidth between the maximum frequency and the minimum frequency cannot exceed 12.5 Mbit/s. For the frequencies of the P frequency band in this example, the absolute value of the difference between the minimum frequency and the maximum frequency cannot exceed 62.
