ABSTRACT:
Communication system of a plurality of switching nodes connected in a closed ring. A switching stage at each node transmits words of data from node-to-node in a time-division multiplexed data stream. Data can be inserted onto the ring by each switching stage, and data addressed to a switching stage is removed form the ring by that switching stage. Data words are loaded into input registers at each switching stage on the leading edge of a clock pulse, and decoding occurs within each switching stage during the clock pulse. A received word may be transmitted to a succeeding switching stage, or may be removed form the ring and stored in an output register on termination of a clock pulse.
