Climate Unit
The climate unit maintains the internal temperature and humidity inside the
cabinet. The climate unit is mounted in the door of the cabinet.
Two types of climate units are available:
• Combined climate unit that provides cooling by use of heat exchanger
and refrigeration units
• Heat exchanger climate unit that provides cooling by use of a higher
efficiency heat exchanger unit.
Both types of climate units include heating elements and the heat
exchanger function is DC powered.
Number of units: 1
CDU
The Combining and Distribution Unit (CDU) 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 allows
several dTRUs to share antennas.
The CDU combines transmitted signals from several transceivers, and
distributes the received signal to several transceivers. The CDU supports
EDGE. Three CDU types are used in the RBS 2106 to support all configurations:
• CDU-F is a filter combiner intended for high capacity solutions (baseband
hopping only).
Number of units: 1 – 3
• CDU-G can be configured either for high capacity or for high coverage. It
is a combiner that can be used for synthesizer or baseband hopping.
Number of units: 1 – 3
• CDU-K can be configured either for high capacity or for high coverage. It is
a combiner that can be used for synthesizer or baseband hopping.
Number of units: 1 – 6
CXU
The task of the Configuration Switch Unit (CXU) is to cross-connect the CDU
and the dTRU in the receiver path. The CXU enables a cabinet to be expanded
or reconfigured 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 used to connect the CXU to the dTRUs
and the CDUs.
