Multiple channel data communication system

摘要

A multiple channel communications system and method for communication among multiple channels using a channel selectable MODEM. The system is comprised of a coaxial cable, a variety of interface units with attached communicating devices and a channel bridge. The interface units include a MODEM and a microprocessor based support element adapted for the attached communicating device. The channel bridge includes two or more MODEMs and a microprocessor based computer for receiving data from one MODEM and transmitting the data on another MODEM.
