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 section of
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.
