Abstract

L'invention concerne un système de distribution de flux de données de téléphonie numérique destiné à être employé dans un bâtiment ou dans un établissement et utilisant des lignes à courant alternatif (105) comme ligne de communications. Ce système de distribution transmet des signaux et des données sans avoir recours à des lignes téléphoniques continues. Il comprend un bloc de base (104) connecté à une unité d'interface (102) d'abonné qui est, à son tour, connectée à un réseau public de communications. De plus, le bloc de base (104) comprend une interface avec les lignes à courant alternatif (105), qui permet de transmettre les signaux de communications aux postes individuels (106a, 106b,...106e). Ces derniers (106a, 106b,...106e) acceptent des installations téléphoniques standard telles que téléphones, standards, télécopieurs et modems. Dans un mode de réalisation préféré de l'invention, un système de codage/décodage MDF est utilisé pour faciliter la transmission des signaux numériques et pour améliorer la qualité du système, ce qui réduit les erreurs et permet d'obtenir une plus grande immunité au bruit.
