Abstract: The present PCM switching element is intended to be used in digital telephone exchanges for the making of switching or concentration stages of whatever capacity. … In fact, structures consisting of a plurality of such elements are easily performed thanks to use of a bit associated with each outgoing PCM channel, called "busy bit". … The switching element can be controlled by a commercially available microprocessor and can be made as an integrated circuit.
