    RIVER TO A EVICE The Line Driver (ME0002A-V35) 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. However, tail-circuit applications require connection to another piece of DCE equipment, such as a multiplexor.
