G.703 DTE Interface
The G.703 DTE interface is either two BNC
connectors (Transmit and Receive) for a 75-ohm
unbalanced interface, or a DB15-type socket connector
(Table D-2) for a 120-ohm balanced interface. For
information about using Relay Contact Sense for external
DTE loopback, refer to the Extrn DLB configuration
option in the
DTE Interface Configuration Options
section
of Appendix C.
The G.703 DTE cable (Figure D-1) is typically
supplied by a DTE vendor. It is made of shielded
twisted-pair wires (22 AWG). The cable connector is a
DB15 plug. Be sure to connect the shield ground only at
the E1 NTU end to prevent ground loops.
