At the rear of BIU, input and output ports are seen for each MDBU. The name of all the ports
are silk printed as "#1, #2, #3 and #4." Referring to the table above, you need to feed right
signals to input and output ports of corresponding MDBU.
For each port, TX signals and RX signals are separated from each other. You don't have to
terminate unused ports unless you want to.
BIU interface with Base station Transceiver
Basically, BIU has different TX and RX ports, and so, you have only to connect input
and output ports.
