Note:
4.5.4 RX Connection from Antenna to dTRU
Connection in the RX path is performed using the CXU. It varies,
depending on the basic configurations used and the position in the
cabinet. To avoid having to change cables for different configurations,
the connections are set up automatically by the software.
The TX antenna connections are independent of the CXU.
The tables below show how TMAs and their associated bias injectors
are connected to configurations using TMAs.
