Abstract
Système de communication intégré, caractérisé en ce que les bureaux à large bande (18) sont interconnectés par des canaux de signalisation commun (19) par lesquels l'information de signalisation requise pour établir et relacher des appels téléphoniques est échangée, et qu'à chacun des équipements d'abonné (1, 2,...,n) on attribue un circuit de tonalité (40) pour transmettre un signal de test se trouvant dans la bande vocale et utilisé pour déterminer avant l'établissement de l'appel vidéo si l'appel téléphonique associé a déjà été établi.
