Title (EN) TELEPHONE LINE INTERFACE OPTION MODULE
(FR) MODULE A OPTIONS POUR INTERFACES DE LIGNES TELEPHONIQUES
Abstract:
(EN) Apparatus (option module) (50) for interfacing an electronic device (main module) (10) to a telephone network. The invention contemplates that the main module, in a preferred embodiment, is a text-to-speech device. The interconnection of an electronic device with the telephone network is generally controlled by government regulations. Since there are many governments, there are many different sets of regulations. The option module is an implementation of a telephone line interface that isolates a main module, in particular, a text-to-speech device, from different and/or changing regulations.
(FR) Appareil (module à option) (50) pour connecter un dispositif électronique (module principal) (10) à un réseau téléphonique. Dans un mode préféré de réalisation, le module principal est un dispositif texte-parole. L'interconnexion d'un dispositif électronique avec le réseau téléphonique est généralement régie par une réglementation administrative. Les administrations étant nombreuses, il existe de nombreuses réglementations qui sont différentes les unes des autres. Le module à option constitue une mise en o^euvre d'une interface de lignes téléphoniques qui met un module principal, notamment un dispositif texte-parole à l'abri des divergences et/ou des modifications des réglementations.
