摘要：An electronic switching system using digital sampling and time divisionmultiplexing to provide virtual connections between a plurality of external circuits. Eachexternal circuit is connected to the matrix switch via respective line interface units (220,320, 420). The conditioned external circuit signals are sampled by switch modules (210,310, 410) and the time sampled information is exchanged between switch modules (210,310, 410) via two switch buses (101, 102) under the control of a timing and control unit(110). Information transferred between switch modules (210, 310, 410) is synchronised toa cyclic time interval count generated by the timing and control module (110) andpresent on a control bus (100). Information transfers between external circuits aretransparent to the switching system and its control unit.
