Abstract: A probe for fault-actuation devices has a transistor which is utilized to insert a reference signal into a fault-insertion point. The emitter and collector are connectable to the fault-insertion point and a reference signal and a capacitor with a capacitance greater than the capacitance of parasitic components is connected between the base and the emitter.

Abstract: The PCM switching network is based on the use of switching units (UC1a ... UC8c) each equipped with a local controller using a microprocessor (CTR1a ... CTR8c), ancillary circuits for diagnosis (CDTE1 ... CDTU5), ancillary circuits for exchanging messages relating to network control between the local controllers (CRT1a ... CTR8c) and between local controllers and the distributed telephone control units (CTFa ... CTFc), and ancillary circuits (RTBE1 ... RTBU5) providing virtual channels (on the speech channels themselves) for transmission of said messages in a direction opposite to that of speech. Said switching units (UC1a ... UCBc) make it possible to provide self-routing modular PCM switching network structures for distributed-control telephone exchanges.

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.
