DUW for 3G
DUS for 4G

Radio Base Station (RBS) is the commercial name given to the family of Base Stations developed by Ericsson, typically constituting a sizable part of the Radio Access Network (RAN). Radio Base Station is also the generic name to be used instead of BTS (Base Transceiver Station ) which are typically denoting GSM-era radio base station technology. For other vendors, specific equipment names are used such as Huawei DBS (Huawei DBS3900 for example) or NSN Flexi base stations.

RBS can be used for GSM (GERAN) with DUG cards, UMTS (UTRAN) with DUW cards, and LTE (eUTRAN) with DUL/DUS cards.

The RBS site can be interconnected to the rest of the RAN with a SIU card (Site Integration Unit) which use either electrical, microwave or optical backhaul to the rest of the RAN and also provides Abis over IP connectivity for GSM base station.

RBS runs the embedded Operating System OSE from Enea from Sweden.

Example
The RBS6000 cabinet usually uses these cards to achieve function:

DXB Distribution Switch Board,
DXU Distribution Switch Unit,
IXU Interface and Switching Unit
DUG cards for GSM (GERAN) aka "Digital Unit GSM"
DUW cards for UMTS (UTRAN)
DUL cards for LTE (eUTRAN)
DUS cards for combined GSM, UMTS and LTE service
ECU Energy Control Unit,
RUG Radio Unit GSM,
RUS Radio Unit all Standards,
RRUS Remote Radio Unit all Standards,
TCB Transceiver Control Board
BDM Battery Distribution Module
BFU Battery Fuse Unit
CDU Combining and Distribution Unit,
CXU Configuration Switch Unit,
FCU Fan Control Unit,
PDU Power Distribution Unit,
PSU Power Supply Unit,
RXU Receiver Unit,
SAU Support Alarm Unit,
SCU Support Control Unit,
TMA_CM, TXU Transmitter Unit

A legacy version of the RBS is the RBS2000 which usually has a combination or subset of these hardware cards:

Power Supply Unit (PSU)
Distribution Switch Unit (DXU)
Internal Distribution Module (IDM)
Double Transceiver Unit (dTRU)
Configuration Switch Unit (CXU)
Combining and Distribution Unit (CDU)
AC or DC Connection Unit (ACCU/DCCU)
Fan Control Unit (FCU)
DC filter
