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.
