DSX-1 Port DTE Interface

This cable is typically supplied by a DTE vendor and is a 22 AWG solid, individually shielded twisted pair cable with drain wire (see Figure B-4). The cable connector is a DB15 plug. Be sure to connect the shield ground only at the DSU/CSU end as shown in Figure B-4 to prevent

ground loops. The DTE (DSX-1) interface connector is a DB15-type socket connector (see Table B-3). Refer to the Extrn DLB configuration option in the DTE Interface Options section in Appendix B of the ACCULINK 315x Channel Service Unit Operator's Guide or the ACCULINK 316x Data Service Unit/Channel Service Unit Operator's Guide for more information.
