KDU127174/4 Ericsson RBS 6000 Series Base Station Module

The Ericsson KDU127174/4 is a DUW 41 01 Digital Unit, a baseband processing module used within Ericsson’s Radio Base Station (RBS) infrastructure. This unit handles digital signal processing functions essential for mobile network operation, managing the interface between the radio transmission chain and the core network backhaul.

The DUW 41 01 forms part of Ericsson’s macro base station portfolio, typically deployed in RBS 6000 series installations supporting 2G, 3G, and early 4G network configurations. It works in conjunction with Radio Units and other system modules to deliver cellular coverage and capacity.

This is a legacy component from Ericsson’s earlier generation base station equipment. While still found in operational networks worldwide, it has been superseded by newer digital unit variants in current deployments. It remains relevant for network maintenance, spares provisioning, and capacity expansion of existing installations.
