DTE Drop/Insert Interface
The DTE Drop/Insert (DSX-1) 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 DTE LB on Contact configuration option in
DTE Interface Configuration Options
The DTE Drop/Insert (DSX-1) cable (Figure D-3) 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.
