V.24/X.21 AND X.21/V.24 INTERFACE CONVERTERS

3. General

The V.24/X.21 Interface Converter Model IC933A
connects and converts from V.24 DTE to X.21
DCE. Model IC944A connects and converts from
X.21 DTE to V.24 DCE. Users can take advantage
of high-speed trunk lines with X.21 interfaces and
still use existing V.24 multiplexers, modems, and
terminals. The compact, lightweight conversion
unit provides complete electrical and mechanical
conversion. It operates without mains power supply
by using ultra low power from the standard
RS-232C/V.24 data and control signal voltages.
