Abstract: A telecommunications digital signal cross-connect panel for interfacing multiplexer equipment having as many as 84 circuits and digital loop carrier equipment having at least 84 circuits. The panel includes 84 multiplexer ports, 84 carrier ports, 84 multiplexer cross-connect ports, and 84 carrier cross-connect ports. The panel also includes edge connector sockets which are each electrically connected to a corresponding one of the multiplexer cross-connect ports and a corresponding one of the multiplexer ports. The panel includes two edge connector cards which are each selectively insertable by the user into individual ones of the 84 edge connector sockets. Each of the edge connector cards is connected by a cable to a set of test access sockets.
