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.
