Abstract

L'invention a pour objet un procédé pour la transmission d'informations de taxation à des raccordements d'abonnés et pour l'émission d'impulsions de taxation à l'interface a/b dans un système local de commutation et de transmission agencé sous forme d'une cellule radio locale constituée par une station fixe radio centrale et par une pluralité de raccordements d'abonnés décentralisés et qui est connectée, en tant que central téléphonique local ou privé, au réseau téléphonique public. Le procédé selon l'invention est caractérisé en ce qu'on mémorise dans la station de base de chaque cellule radio, un tableau de répartition des zones en fonction de la distance, adapté à l'emplacement et contenant, pour le réseau local et pour tous les raccordements téléphoniques en dehors de ce réseau, les informations d'impulsions d'horloge pour le callcul de la taxation, et en ce que, lors d'une communication en cours partant d'un abonné radio, le numéro d'appel choisi par celui-ci est comparé automatiquement avec ledit tableau de répartition et l'information appropriée relative à l'impulsion d'horloge est prélevée et transmise au raccordement de l'abonné, lequel génère des impulsions de taxation standards correspondant aux impulsions d'horloge transmises et les émet à l'interface a/b. L'impulsion de taxation standard de 12 kHz ou de 16 kHz ne peut être transmise par l'intermédiaire de canaux radio dont la largeur de bande de transmission est limitée à la bande vocale de 300 Hz à 3400 Hz. Grâce à la solution appliquée, l'impulsion de taxation n'a pas à être transmise, comme c'est le cas dans les autres procédés connus, sous forme de signal de remplacement intégré dans ladite bande vocale, ce qui perturbait, comme on le constate par expérience, la transmission des signaux des modems et des télécopieurs.
