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: A low power consumption output stage is provided for ECL line drivers for digital transmission lines in which two output transistors are connected through a switching circuit to a common bias current generator so that only that transistor which transmits to the line a low level signal receives bias current.

Abstract: A PCM switching network based on the use of switching units each equipped with a local controller using a microprocessor, ancillary circuits for diagnosis, ancillary circuits for exchanging messages relating to network control between the local controllers and between local controllers and the distributed telephone control units, and ancillary circuits providing virtual channels for transmission of the messages in a direction opposite to that of speech. The switching units make it possible to provide self-routing modular PCM switching network structures for distributed control telephone exchanges.

Abstract: A PCM switching network based on the use of switching units each equipped with a local controller using a microprocessor, ancillary circuits for dialogue among the controllers and ancillary circuits for diagnosis, failure localization and reconfiguration. The switching units make it possible to provide self-routing modular PCM switching network structures for distributed-control telephone exchanges.
