    Abstract: A stored program control system, more particularly for telecommunications apparatus, includes a self-correcting, solid-state mass memory, interfaced with a processing system through a controller. The mass memory is implemented using charge-coupled technology and comprises one or more memory modules connected by a biodirectional internal bus with a control module. Each memory module consists of one or more rows of memory circuits and an input/output device connecting these memory circuits with the internal bus. The control module consists of a microprogrammed time base, an adressing control circuit, and a self-correcting logic circuit, the control module being connected to the internal bus by a further input/output device for distributing data to the memory modules of the controller.

    Abstract: A stored-program control system for a telephone exchange or the like comprises processing units coupled to several main memories and to several mass memories. Each mass memory includes one or more memory modules each with one or more rows of shift registers of the charge-coupled type, operating in a serial-parallel-serial mode, and a control module equipped with a self-correcting logic and a microprogrammed time base.

    Abstract: A call monitor for a telephone exchange, including a processor intervening in the establishment of a connection between associated line links with the aid of a switching network, comprises a first memory storing information about each line link and a second memory containing codes that identify all possible states of a connection of interest to the processor along with all intervening conditions termed evolutions. During a time slot allocated to a particular line link, a multibit comparator receives data from the first memory concerning a connection involving that line link, along with updating information from the line link itself, on one set of inputs and further receives, on another set of inputs, a succession of evolutionary codes read out from the second memory until a match is detected; the read-out is then terminated and an instruction, if required, is sent to the processor and/or to the switching network.

    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.
