Abstract

On décrit un système et un procédé qui permettent de déconnecter un dispositif (214) de télécommunication d'une ligne (222) de télécommunication pour ainsi libérer la ligne de télécommunication pour d'autres communications telles que des appels d'urgence. Un détecteur (210) de signal surveille la ligne de télécommunication pour détecter la présence d'un signal prédéfini. Lorsque le détecteur de signal détecte le signal prédéfini, ceci entraîne un commutateur (224) ou un relais à déconnecter le dispositif (214) de télécommunication de la ligne (222) de télécommunication. Un dispositif éloigné sert à détecter une condition prédéfinie à un endroit stratégique. Lorsque le dispositif éloigné détecte la condition prédéfinie, soit par détection directe soit par le biais d'un opérateur, un émetteur situé dans le dispositif éloigné envoie un signal à un récepteur couplé au commutateur, ceci déconnectant le dispositif de télécommunication de la ligne de télécommunication. Lorsque le système de l'invention déconnecte le dispositif de télécommunication, la ligne de télécommunication est libre pour d'autres communications.
