DTE Drop/Insert Interface

The DTE Drop/Insert interface connector is a
DB15-type socket connector (Table D-2). For information
about using Relay Contact Sense for external DTE
loopback, refer to the Extrn DLB configuration option in
the DTE Interface Configuration Options
Appendix C.
The DTE Drop/Insert cable (Figure D-2) 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 DSU/CSU end to prevent ground loops.
