DTE Drop/Insert Interface
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

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.
