Abstract

Un ensemble de filtres passifs répartis (12) du service téléphonique traditionnel (POTS plain old telephone system), qui est associé à un ensemble respectif de dispositifs de communications du POTS, découple une voie du POTS d'une liaison téléphonique, tout en autorisant, sans la perturber, une seconde voie de communications (41) (par exemple, DSL, ADSL, SDSL, RADSL, VADSL, etc.), sur la liaison téléphonique qui est utilisée par un modem. D'un point de vue architectural, le système (10) à filtres DPF comporte une pluralité de dispositifs de communication du POTS, tels que des téléphones, et une pluralité de filtres DPF (10) correspondant respectivement à chacun des dispositifs de communications (33) du POTS qu'ils relient à la liaison téléphonique. Chacun des DPF comporte un mécanisme de commande automatique et un filtre du POTS (12). Ledit mécanisme de commande automatique est conçu pour isoler le filtre du POTS lorsqu'un dispositif respectif de communications du POTS est raccroché. Chaque DPF (10) est conçu pour permettre des communications POTS sur une voie POTS de la liaison téléphonique avec le dispositif respectif de communication du POTS (33) lorsque le dispositif de communication du POTS est décroché. En outre, un second dispositif de communications, tel qu'un dispositif de communications DSL (par exemple, ADSL, SDSL, RADSL, VADSL, etc.) est connecté à la liaison téléphonique et communique des signaux sur une seconde voie. Le POTS et la seconde voie sont en communication sur la liaison téléphonique de manière simultanée sans brouillage notable.
