Abstract

L'invention a trait à un procédé de détection de l'utilisation de postes dans des centraux téléphoniques privés automatiques et à un montage pour la mise en oeuvre du procédé. Elle a pour objet un montage de détection de l'utilisation de postes dans des centraux téléphoniques privés, équipés de plusieurs postes, avec un bloc de commande relié d'une part, par un circuit de couplage, à la ligne de service entre le central et les différents postes, et relié à un appareil de données. Un dispositif de sécurité 15 est prévu, relié aux sorties de chaque récepteur 1, 2, 3, 4 raccordé au codeur 12. Applications : installations téléphoniques privées.The invention relates to a method for detecting the use of sets in automatic private telephone exchanges and to an arrangement for implementing the method. Its object is a set-up for detecting the use of sets in private telephone exchanges, equipped with several stations, with a control unit connected on the one hand, by a coupling circuit, to the service line between the central and the various stations, and connected to a data device. A safety device 15 is provided, connected to the outputs of each receiver 1, 2, 3, 4 connected to the encoder 12. Applications: private telephone installations.
