Figure 5 Standard Hardware Units
ACCU - AC Connection Unit
The ACCU distributes the incoming AC power supply voltages to the PSUs.
The unit also contains AC filter equipment.
Number of units: 0–1
CDU - Combining and Distribution Unit
The 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. There is a
maximum of three CDUs in one RBS 2207.
The CDU distributes the received signal to several transceivers. The CDU
supports EDGE. Both CDU-G and CDU-J is used in the RBS 2207. CDU-G
and CDU-J can be configured either for high capacity or for high coverage. It is
a combiner that can be used for synthesizer hopping. To achieve capacity, the
