CV-SERIAL is an E1 / T1 G704 CSU-DSU converter to a Serial interface RS530 / RS232 / V35 / X21

CV-Serial connects a terminal equipment - router or such equipment, with a RS530, V35 or X21 synchronous serial interface to an E1 or T1 netowork.  It performs 64 kbps Timeslot extraction and generates a synchronous data interface with Nx64 kbps speeds.

CV-Serial works also for asynchronous applications to connect RTU, remote control or metering equipment at a speed up to 38.4 kbps to the E1 or T1 network. The link is transparent to traffic and RS232 control signals
