Definitions

  • This invention relates generally to blocking a list of sequences of one or more digits from being dialed on a phone line, and more particularly to a programmable device coupled to the phone line to effectuate such blocking.
  • Such diverse purposes include allowing an individual to call an automated or interactive service through the telephone system to obtain all sorts of different information imaginable, such as sports scores, stock quotes, etc.
  • the telephone system is also used by users of personal computers, to allow these users to communicate to one another via commercial online services or the Internet.
  • Such users typically employ a modem that converts the digital signals understandable by a computer to analog signals that can be sent over the telephone system.
  • Many industry analysts and pundits suggest that even more uses for the telephone system will come into existence as time unfolds.
  • the telephone system may have become such a popular vehicle for so many new applications because of its universality. Nearly everyone in the United States and most other developed countries has a phone. Perhaps more significantly, upon obtaining access to a phone line, a party quite literally usually has access to anyone and anything else also coupled to the telephone system. That is, the telephone system is not regionalized or otherwise does not typically prevent one party of the telephone system from contacting any other party also coupled thereto. everyone on the phone system basically has access to everyone and everything else also on the system.
  • Parents may not want children accessing particular automated and interactive services offered through the phone system via 1 -900 numbers that may be adult-oriented, or that may be very expensive.

Abstract

Cette invention se rapporte à un dispositif de censure d'appels permettant d'interdire la composition d'un numéro sur une ligne téléphonique par verrouillage d'un quelconque élément d'une liste de séquences comportant au moins un chiffre. Ledit dispositif comporte une première interface, une seconde interface, une mémoire, un organe d'entrée et une unité de commande. La première interface assure la connexion fonctionnelle à un appareil téléphonique. La seconde interface assure la connexion fonctionnelle à la ligne téléphonique. La mémoire sert à stocker la liste des séquences. L'organe d'entrée est fonctionnellement couplé à la mémoire et il permet d'ajouter une séquence comportant au moins un chiffre à la liste des séquences ou de retirer une telle séquence de ladite liste. L'unité de commande, qui est fonctionnellement couplée à la mémoire ainsi qu'à la première interface et à la seconde interface, sert à gérer la liste des séquences, à comparer une séquence composée sur l'appareil téléphonique à la liste des séquences et à déconnecter l'appareil téléphonique de la lige téléphonique lorsque la comparaison aboutit à une concordance.
