The DTE Drop/Insert (DSX-1) interface connector is a DB15-type socket connector (Table E-2, DTE Drop/Insert (DSX-1) Connector). For information about using Relay Contact Sense for external DTE loopback, refer to the Extrn DLB configuration option in DTE Interface Configuration Options in Appendix C, Configuration Options.

The DTE Drop/Insert (DSX-1) cable (Figure E-3, DTE Drop/Insert (DSX-1) Cable) is typically supplied by a DTE vendor. It is made of shielded twisted-pair wires (22 AWG). The cable connector is a DB15-type plug connector. Be sure to connect the shield ground only at the DSU/CSU end to prevent ground loops.
