Configuring the TRX Four-in-One Output

This describes how to configure the DFCU and its antenna feeder attributes for the BTS3012, BTS3012 II, or BTS3012AE to achieve the four-in-one output of TRXs.

Scenario	BSC initial configuration
Mandatory/Optional	Optional. Only one DFCU is configured when the four-in-one output of TRXs needs to be implemented in the BTS3012, BTS3012 II, or BTS3012AE.

NOTE:

• The DFCU can independently provide the four-in-one output of TRXs.
• The DFCU cannot be bound to the QTRU.
• The DFCU should not be configured in slot 20 of the DAFU subrack in the BTS3012, BTS3012 II, or BTS3012AE. The slots on both sides of the DFCU slot should not be configured with the DFCU or the DFCB.
• The TRX to be tuned must be configured on downlink tributary A of the DFCU. Tributary B should not be configured with TRXs.
• The frequency band type of the DFCU must be the same as that of the TRX in the BTS.
