Abstract
A telephone system is described wherein a plurality of subscriber locations are each connected to a central office by a single subscriber loop. A signalling method is used for transmitting information between each subscriber location and a cental office. Bursts of time compressed multiplexed full duplex digital signals are synchronously transmitted at an information bit rate of between about forty and eighty kilobits per second and at a burst cycle of between about 0.8 and 4.0 milliseconds. Each of the bursts is comprised of bits defining at least one voice channel, at least one data channel, and at least one signalling channel, with at least one synchronizing bit at the front and back of each burst.
