Abstract
A self-switched in-band signaling communication apparatus is disclosed which enables the switching of the signaling mode to the data mode on a single transmission line between a data terminal equipment or data communication equipment and the data port of a satellite communications controller, and the opposite switching from the data mode to the signaling mode under a single control bit. Signaling to and from the data port of the satellite communications controller is carried out using conventional dialing pulses at a signaling rate which is independent of the line data rate. The apparatus provides for the multipoint communication between a plurality of data terminal equipments using a unique multipoint turn-around process which provides a mobile bandwidth capability for the communications system.
