Abstract
(EN)
A phone line connected communications device utilizing a digital access arrangement (DAA) having line side circuitry including a telephone network interface and system side circuitry including a host system interface, the line side circuitry and the system side circuitry being separated by a high voltage isolation barrier. In accordance with the invention, the high voltage isolation barrier and other DAA circuitry are configured such that information may be communicated between the system side circuitry and the line side circuitry in a digital format. In one embodiment of the invention, multiple datapaths are provided across the digital high voltage isolation barrier for purposes of supporting one or more modem standards. In a further embodiment of the invention, additional datapaths are provided across the high voltage barrier for simultaneous support of a home networking standard utilizing, for example, the preexisting copper wire infrastructure of a home residence.

L'invention porte sur un dispositif de communication connecté à une ligne téléphonique qui utilise un dispositif d'accès numérique (DAN) comprenant un circuit secondaire de ligne incluant une interface de réseau téléphonique et un circuit secondaire du système incluant une interface de système hôte ; le circuit secondaire de ligne et le circuit secondaire du système étant séparés par une barrière isolante haute tension. Selon l'invention, la barrière isolante haute tension et d'autres circuits DAN sont configurés de sorte que l'information puisse circuler dans un format numérique entre le circuit secondaire du système et le circuit secondaire de ligne. Dans une forme de réalisation de l'invention, plusieurs chemins de données sont prévus au niveau de la barrière isolante haute tension pour supporter un ou plusieurs standards de modem. Dans une autre forme de réalisation de l'invention, des chemins de données additionnels sont prévus au niveau de la barrière isolante haute tension pour supporter simultanément un standard de réseau domestique utilisant, par exemple, l'infrastructure existante en fils de cuivre d'une habitation.
