Title
(EN) TELEPHONE COMMUNICATION SYSTEM AND METHOD OVER LOCAL AREA NETWORK WIRING
(FR) SYSTEME DE COMMUNICATION TELEPHONIQUE ET PROCEDE APPLIQUE A UN CABLAGE DE RESEAU LOCAL
Abstract
(EN)
A method and apparatus for enabling a local area network wiring structure to simultaneously carry digital data and analog telephone signals on the same transmission medium. It is particularly applicable to a network in star topology, in which remote data units (e.g. personal computers) are each connected to a hub through a cable comprising at least two pairs of conductors, providing a data communication path in each direction. Modules at each end of the cable provide a phantom path for telephony (voice band) signals between a telephone near the data set and a PBX, through both conductor pairs in a phantom circuit arrangement. All such communication paths function simultaneously and without mutual interference. The modules comprise simple and inexpensive passive circuit components.
(FR)
L'invention concerne un procédé et un appareil permettant à une structure de câblage pour réseau local de transmettre simultanément des données numériques et des signaux téléphoniques analogiques sur le même support de transmission. Cette invention convient en particulier à un réseau en étoile, dans lequel des unités de données à distance (p. ex. ordinateurs personnels) sont chacune connectées à un concentrateur à travers un câble comprenant au moins deux paires de conducteurs, fournissant une voie de communication de données dans chaque direction. Des modules à chaque extrémité du câble fournissent une voie fantôme pour signaux téléphoniques (bande vocale) entre un téléphone près d'un modem et un autocommutateur privé, à travers les deux paires de conducteurs dans un circuit fantôme. Toutes ces voies de communication fonctionnent simultanément et sans interférence mutuelle. Ces modules comprennent des composants de circuit passif simples et économiques.
