RBS Product Description
• CDU-K can be configured for large capacity or large coverage, with
12 transceivers uncombined in one cabinet. It also allows dual band
configurations with 6 transceivers for each frequency. Configurations with
4-way receiver diversity in three sectors can also be built in one cabinet.
Number of units: 1–6
CXU-10
This variant of Configuration Switch Unit (CXU) cross-connects the CDU and
the dTRU in the receiver path. The CXU makes it possible to expand or
reconfigure a cabinet without moving or replacing any RX cables. The RX
inputs/outputs on the dTRU and the CDU are positioned so that they minimize
the number of cable types needed to connect the CXU with the dTRUs and the
CDUs. The CXU is configured by means of software.
Number of units: 1–2
DCCU-11
This variant of the DC Connection Unit (DCCU) distributes incoming DC power
to the PSUs.
Number of units: 0–1.
DCCU-13
This variant of the DC Connection Unit is the interface for +24 V DC power
or battery backup.
Number of units: 0–1
dTRU
This variant of the Double Transceiver Unit (dTRU) contains two TRXs for
transmission and the reception of two radio carriers. It has a built-in combiner
with the optional possibility of combining two TX signals into one TX output. It
can also be configured for four-branch RX diversity for further improvements in
sensitivity. Variants of the dTRU support GMSK, 8-PSK, 16-QAM and 32-QAM.
Number of units: 1–6
DXU-23
This variant of the Distribution Switch Unit (DXU) is the central control unit for
the RBS. It supports the interface to the BSC, and it collects and transmits
alarms. The DXU controls the power and climate equipment of the RBS. It
has a removable compact flash card that enables a faulty DXU to be replaced
without needing to load RBS software from the BSC. The DXU is also the
