Patent

CA 2235459

A system and method for remotely monitoring the status of one or more extension phones in a distributed telephone network. Preferably the remote monitoring station has bi-direction communication capabilities such that calls to one or more extensions can be intercepted in addition to status monitoring. Greater flexibility is provided by two separate communication channels, one for digital signals relating to call status and one for analog signals representing voice traffic.

L'invention est constituée par un système et une méthode de télésurveillance de l'état d'un ou de plusieurs téléphones supplémentaires dans un réseau téléphonique réparti. Dans la concrétisation privilégiée de l'invention, la station de télésurveillance dispose de fonctions de communication bidirectionnelles qui permettent d'intercepter les appels destinés à un ou à plusieurs téléphones supplémentaires en plus de surveiller ces téléphones. Une plus grande souplesse est obtenue en utilisant deux voies de communication distinctes, l'une pour les signaux numériques en rapport avec l'état des appels et l'autre pour les signaux analogiques des communications vocales.
