AbstractA digital switching system which is comprised of a circuit switching network under control of a main system control for carrying and switching transmission paths for signals transmitted between peripherals (i.e. lines, trunks, service circuits, etc.), and a separate message switching network under control of the main system control for carrying supervisory and control signals related to the status of the peripherals between peripheral unit management circuit controller(s) and the main system control.
