Abstract
(EN)
A high speed digital transmission method employing an analog subscriber's loop (e.g., an existing telephone copper cable), a subscriber accommodation system used for the high speed digital transmission method, a subscriber terminated side accommodation device and an accommodating station side accommodation device. A subscriber distributor connected with a plurality of subscribers is disposed on the subscriber terminated side of a subscriber's loop provided according to the high speed digital transmission method. A low frequency band part is employed for a control channel and a high frequency band part is employed for one or more speech channel. The speech channel is controlled using the control channel, and the subscribers can communicate using the same subscriber's loop.
(FR)
L'invention concerne un procédé de transmission numérique à grande vitesse utilisant une ligne d'abonné numérique (par exemple un câble téléphonique en cuivre existant), ainsi qu'un système de prise en charge abonné employé selon ce procédé de transmission numérique à grande vitesse, un dispositif de prise en charge coté terminaison abonné, et un dispositif de prise en charge coté station de prise en charge. Un distributeur abonné connecté à une pluralité d'abonnés est placé sur le coté terminaison abonné d'une ligne d'abonné, conformément audit procédé de transmission numérique à grande vitesse. Une partie bande basse fréquence est par ailleurs employée par un canal de commande et une partie bande haute fréquence utilisée par une ou plusieurs voies téléphoniques, chacune de ces voies téléphoniques étant régie à l'aide de ce canal de commande et les abonnés pouvant communiquer à l'aide de la même ligne d'abonné.
