Abstract

L'invention concerne un dispositif de transmission d'informations destiné à relier plusieurs abonnés à un central. Ce dispositif comprend un système de transmission à multiplexage de fréquence 16, 17, 18 raccordé à une voie de transmission 3 et, par un dispositif de commutation 13, à un dispositif de commande 14 qui commande directement le dispositif 13 relié à un poste terminal du côté du central, et, par l'intermédiaire d'un dispositif de télécommande 15, un dispositif 23 d'affectation de fréquences relié à un poste terminal du côté abonné Application notamment aux systèmes de transmission à multiplexage de fréquence.The invention relates to an information transmission device intended to connect several subscribers to an exchange. This device comprises a frequency multiplexing transmission system 16, 17, 18 connected to a transmission path 3 and, by a switching device 13, to a control device 14 which directly controls the device 13 connected to a terminal station of the side of the exchange, and, by means of a remote control device 15, a frequency allocation device 23 connected to a terminal station on the subscriber side. Application in particular to frequency multiplexing transmission systems.
