Abstract

L'invention concerne une liaison téléphonique bidirectionnelle entre une pluralité de lignes d'abonnés (1, 1*), créant une liaison de transmission par modulations d'impulsions en amplitude des signaux téléphoniques quantifiant les signaux utilisant un train d'impulsions avec un créneau d'échantillonnage (Td) et un intervalle de trame entre les impulsions Tk, et faisant passer des états discrets des lignes d'abonnés de la liaison de transmission dans un bus à câble unique. On propose que les états d'amplitude discrets soient conservés dans le dispositif de mémorisation (6, 6*) des lignes de l'abonné (1, 1*) du circuit de communication pendant une durée équivalente à la différence entre Tk et Td, et que le signal mis en forme de l'état global soit renvoyé aux lignes d'abonnés (1, 1*) immédiatement avant que les états discrets n'arrivent dans le créneau d'échantillonnage normal.
