Unit Description, CXU-10
The CXU is also connected to a CDU-bus. By sending data through the
CDU-Bus, the switches can be set to fulfil one of six supported
configurations.
Inside the CXU there are also some splitters to distribute the incoming
RX-signals to the switches and in some cases directly to an out port.
The RF cables between CDU and CXU are supervised in the CXU. The
RF cables between CXU and dTRU are supervised in the dTRU.
The CDU-bus cable is monitored by the DXU.
9.3 External Interfaces
The CXU has the following connectors:
• Six inputs for RX signals from the CDU
•
Twelve output ports for RX signals to dTRU
•
CDU-bus connector for alarm and configuration settings
•
Power supply connector
The CXU has the following indicators:
• Operational – green
•
Fault – red
