CDU-J
The Combining and Distribution Unit (CDU-J) is the interface between the
transceivers and the antenna system. All signals are filtered before
transmission and after reception by means of bandpass filters. The CDU-J
allows several dTRUs to share antennas.
The CDU-J combines transmitted signals from several transceivers and
distributes the received signal to several transceivers. The CDU-J can be
configured either for high capacity or for high coverage. It is a combiner that
can be used for synthesizer hopping (baseband and synthesizer hopping only)
and supports EDGE. To achieve capacity the CDU-J uses the hybrid combiner
in the dTRU, and with coverage the CDU-J is used in configurations where the
hybrid combiner in the dTRU is not used.
Number of units: 1 – 3
DXU-21
The Distribution Switch Unit (DXU-21) is the central control unit for the RBS. It
supports the interface to the Base Station Controller (BSC), and it collects and
transmits the alarms. The DXU-21 controls the power and climate equipment
for the RBS. It has a removable compact flashcard that enables replacement o
f
a faulty DXU-21 without the need for loading RBS software from the BSC.
The DXU-21 is provided with four connections for transmission interfaces. It
can handle both 2048 kbit/s (E1) and 1544 kbit/s (T1) transmission interfaces.
The DXU-21 supports EDGE.
Number of units: 1
dTRU
The double TRansceiver Unit (dTRU) contains two TRXs used to transmit and
receive two radio carriers.
It has a built-in combiner with the option to combine two TX signals into one TX
output. It is also prepared for four-branch RX diversity for further improvements
in sensitivity.
