Abstract

L'invention concerne une installation de traitement d'informations de canaux téléphoniques. On connecte entre eux des appareils individuels à fonctionnement autonome, travaillant avec une modulation par impulsions codées ou un procédé numérique analogue et le principe de multiplex de temps et présentant tous les composants nécessaires pour le fonctionnement indépendant et le traitement de l'information des canaux téléphoniques, tandis qu'un appareil individuel 1a peut être réglé en tant qu'appareil directeur produisant au moins les impulsions d'horloge de base de synchronisation pour tous les appareils 1a-1d, cette fonction directrice étant reprise par un autre appareil en cas de défaut de l'appareil directeur. Utilisation dans le domaine de la téléphonie en multiplex de temps.The invention relates to an installation for processing telephone channel information. Individual devices are connected to each other with autonomous operation, working with pulse code modulation or an analog digital process and the time multiplex principle and having all the components necessary for the independent operation and information processing of the telephone channels. , while an individual device 1a can be set as a master device producing at least the basic synchronization clock pulses for all devices 1a-1d, this master function being taken over by another device in the event of a fault of the directing device. Use in the field of time multiplex telephony.
