Abstract
A multiplexed data communications modem providing high speed data communication via a single twisted pair of conductors having a distance up to two kilometers between a plurality of data terminals and remote communications equipment is provided. A burst mode ping-pong transmission scheme is utilized. A control portion selectively multiplexes data from each data terminal, and the variation of actual data rate of each data terminal has no effect on channel capacity of the other multiplexed data channels. A plurality of data interface circuits provides an asynchronous/synchronous interface between the multiplexed data terminals and a synchronous transceiver.
