Abstract

La présente addition concerne des modifications apportées au dispositif d'identification des appelants d'un réseau de transmission radio-électrique décrit dans la demande de brevet principal. Les messages de réponse émis par les postes satellites à la suite de la reconnaissance d'un message d'interrogation sont précédés par l'envoi d'une tonalité de fréquence et de durée données, cette tonalité étant détectée par le poste central afin de déterminer la présence ou l'absence de messages de réponse. Application notamment aux réseaux radio-mobiles comportant des relais radio-électriques.
