The Line Driver provides a V.35 DCE (Data Circuit Terminating Equipment)
interface on an M/34 female connector. As a DCE, this interface is designed to
connect to DTE equipment, such as a router. When connecting the V.35 interface
of the Line Driver to your DTE device, use a V.35 straight-through cable (see
Figure 4-3).
Appendix A
describes pin assignments and signal sources for the Line
Driver’s V.35 interface. When purchasing or constructing an interface cable, please
