ACCU-11
The AC Connection Unit (ACCU) distributes the incoming AC power to the
PSUs.
Number of units: 0–1.
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 received signals to several transceivers. The RBS uses three CDU
types to support all configurations:
• CDU-F – a filter combiner intended for high capacity solutions.
• CDU-G which can be configured for either high capacity or high coverage
and used for synthesizer hopping
Number of units: 1–3
