TD-CNV-V.35-1E

Overview

TD CNV-V.35-1E Series gives the interface conversion between G.703 El and V.35. This device provides an economical digital access solution for El and Fractional El network services. With a adapter cable, the Device can link to other DTE Device, such as router, at data rates of 64Kbps to 2048Kbps. User data is placed into the El frame, using only the required number of timeslots. Timeslot assignment is accomplished according to the Data Port speed and manual setting of DIP switches. The main El link may be clocked from the recovered receive clock, from the Data Port clock, or from an internal oscillator.

• Key features
