The terminal block provides four connecting points to the transmit and
receive twisted-pair lines, and a fifth for ground connection. The transmit
and receive pairs are polarity-insensitive.
The transmit pair is connected to the terminals marked XMT (data output
of the modem), and the receive pair is connected to the terminals marked
RCV (data input to the modem).
