  • Concentrator-deconcentrator devices
    Patent number: 4420832
    Abstract: Concentrator-deconcentrator devices for time-division telephone systems, based on the use of symmetrical time-division arrays arranged in terminal modules comprising subscriber and line connecting units to be served and in central modules which provide the connections between these equipments and the exchange to which the device is connected by ensuring variable concentration and improved security.The device is intended for PCM time-division telephone systems.
    Type: Grant
    Filed: April 21, 1980
    Date of Patent: December 13, 1983
    Assignee: Le Materiel Telephonique Thomson-CSF
    Inventors: Jacques E. Salle, Jean A. M. Jossif, Gilbert J. M. Rathier, Jean-Pierre Vales
  • Signalling switching system in a time switching network and time switching network incorporating such a system
    Patent number: 4402078
    Abstract: The system is constituted by a wired logic included in a signalling unit, which also has a microcomputer. This logic is connected on the one hand to the incoming and outgoing signalling junctions of a connection network and on the other to a programmed peripheral marking unit by means of which a central computer supplies correspondence data between an incoming junction channel and an outgoing junction channel.

    Assignee: Thomson-CSF Telephone
    Inventors: Claude Athenes, Jacques E. Salle
  • Clock recovery device
    Patent number: 4327442
    Abstract: A clock recovery device for a digital data receiver. This device includes a first register for generating a clock signal having the same nominal frequency as the distant clock signal; a second register for detecting the pulses of the received signals, regenerating these received signals and then generating synchronization pulses, and a third register for retiming the regenerated pulses.

  • Modular time-division switching network
    Patent number: 4317008
    Abstract: The modular switching network for time-division telephone exchanges, which may be applied to small-capacity time-division telephone exchanges, is constituted by the direct connection of pairs of subscriber and trunk line connecting units by PCM digital trunks, each connecting unit comprising a concentration-deconcentrator device for serving the subscribers associated with this connecting unit.
