• BNC coaxial
• RJ-45.
Terminal Block Option
The terminal block contains five screws for connecting the transmit and receive
pairs and ground, if present. The transmit pair is connected to the terminals
marked XMT, the receive pair – to the terminals marked RCV, while the fifth screw
is a terminal for optional ground connection. As a terminal block option, a
terminal block protective cover is placed over the interface connectors. Modems
operating over 2-wire lines use XMT terminals for both the transmit and receive
pairs.
