Abstract: A path testing device for a time channel connection network employs a decision and control network which, through its permanent connection with a central processing computer, delivers control signals to various elements connected with the central memory for selecting and storing an available time channel on one of a plurality of time division multiplex communication paths possible through an intermediate stage of a multiple stage interconnection time channel switching network. The path testing device is responsive to an incoming time slot and an outgoing time slot being accessed to and from the input stage and sequentially examines available time slots from a number available within the intermediate time switching stage.
