Connecting the Model 3088RC/A/I (V.35) to a “DCE” device
The Model 3088RC/A/I provides a V.35 DCE (data circuit terminating
equipment) interface on a M/34 connector. As a DCE, this interface is
designed to connect to DTE equipment, such as a router. However, con-
necting the 3088RC/A/I to another DCE device, such as a multiplexer or
G.703 E1 NTU, requires a tailcircuit cable. When connecting the V.35
interface of the Model 3088RC/A/I to your DCE device, use a V.35 tail
circuit cable. Some applications may also require the installation of a tail-
circuit buffer to account for small differences in clock frequency between
the 3088RC/A/I and the V.35 DCE (multiplexer).
