Prepared (also subject responsible if other) No.
Approved Checked Date Rev Reference
• CDU-F is a filter combiner intended for high capacity solutions.
• CDU-G can be configured either for high capacity or for high coverage. It
is a combiner that can be used for synthesizer hopping.
Number of units: 1–3
CXU-10
This variant of the 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 Receiver (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-01
This variant of the DC Connection Unit (DCCU) connects, disconnects, and
distributes the incoming DC power supply to the PSUs and the climate unit.
Number of units: 0–1.
dTRU
The Double Transceiver Unit (dTRU) contains two TRXs for the transmission
and 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, as well as
Voice services over Adaptive Multi-user channels on One Slot (VAMOS).
Number of units: 1–6
DXU-21
This variant of the Distribution Switch Unit (DXU) is the central control unit
for the RBS. It supports the interface to the Base Station Controller (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 makes it
possible to replace a faulty DXU without the need for loading RBS software
from the BSC. The DXU also has four ports for transmission interfaces. It can
handle both 2048 kbps (E1) and 1544 kbps (T1) transmission interfaces. The
DXU supports EDGE on 12 TRXs.
Number of units: 1
FCU
The Fan Control Unit (FCU) controls the fans in the cooling system by
regulating fan speed. The FCU is controlled by the DXU.
