The particular switch concerned here is a Three Stage Time space time (TST) interconnection network and performs the time division circuit switching. The input and output stages are Time Slot Interchangers (TSI) . The central stage is a time multiplexed switch with two ports per address. By exploiting the channel grouping at the central stage as well as reducing the average loading at each internal frame,the three stage multicast switch has potential to remove almost all slot contention blockings.
