摘要: A subscriber termnal for use in a TDM telephone system operating in a multiframe format where each time frame consists of a plurality of time slots, said system including a base switch connected to a plurality of multitime slot data buses for switching encoded data between specified ones of the time slots. A subscriber switch is connected to a plurality of local subscriber lines and to a pair of the data buses for switching encoded data between the subscriber lines and specified time slots on the pair of data buses. The subscriber switch includes a number of subscriber terminals where each terminal is connected to some of the subscriber lines and includes a pair of subscriber switch controllers for controlling the switching of data between the subscriber lines and the pair of buses. Each subscriber terminal provides the capability of encoding, multiplexing and switching data from a plurality of subscriber lines to specified time slots on the pair of multitime slot buses and capability of decoding, demultiplexing and switching other encoded data from specified time slots on the pair of data buses to the subscriber lines.

摘要: Communication processor apparatus for use in a TDM telephone system operating in a multiframe format consisting of a plurality of time frames where each time frame consists of a plurality of time slots having a time slot rate and where the plurality of frames includes signaling frames having supervisory signals where the supervisory signals occur as a signaling bit during each time slot in the signaling frame. The telephone system includes a base switch connected to a plurality of multitime slot data buses for switching encoded data between specified time slots on the buses and also includes a subscriber switch for connecting a plurality of local subscriber lines to time slots on a pair of the buses. The communication processor provides a communications link between the base switch and the subscriber switch and includes a receiver for receiving signaling bits during alternate signaling frames in the form of a message on one of the buses and a transmitter for transmitting sequential signaling bits during a selected signaling frame in the form of a second message on a multitime slot data bus. A central processing unit provides control of the operation of the communication processor.
