Patent

CA 2228903

A telephone switching system 10 comprises a plurality of physical ports 20, and switches removable terminals based on predetermined connection information, wherein such connection information is arranged to be capable of being stored and rewritten in a RAM 60 by inputting from the terminal. When a physical port connecting to a terminal interface 30 is reconnected from a first terminal to a second terminal, a CPU 40 rewrites the connection information stored in the RAM 60 so that an extension number the user desires is stored for the physical port reconnected with the terminal. Thus, connection information established for another terminal is prevented from being reflected as in the prior art, whereby a telephone switching system can be provided which does not cause mismatch of connection information such as an extension number.

L'invention est un système de commutation téléphonique 10 comportant une pluralité de ports physiques 20 qui est utilisé pour commuter des terminaux amovibles en se basant sur des informations de connexion prédéterminées qui peuvent être stockées et réinscrites dans une RAM 60 à partir d'un terminal. Quand un port physique de connexion à une interface de terminal 30 est commuté d'un premier terminal à un second, une unité centrale 40 réinscrit les informations de connexion stockées dans la RAM 60 de façon que le numéro du poste désiré par l'utilisateur soit stocké pour le port physique reconnecté au terminal. Ainsi, les informations de connexion établies pour un autre terminal ne peuvent être réfléchies comme dans les systèmes actuels et on peut donc obtenir un système de commutation téléphonique sans mélange des informations de connexion telles que les numéros de poste.
