E1 Network Interface

The E1 network interface is either two BNC connectors
(Transmit and Receive) for a 75 ohm unbalanced
interface, or an RJ48C, 8-position, unkeyed modular
connector (Table D-1) for a 120 ohm balanced interface.
The E1 120 ohm network interface adapter cable is
shown in Figure D-1.
