Patent

CA 2271761

A telecommunication system that can integrate the capabilities of broadband components with the capabilities of conventional circuit switches. A signalling processor (140) receives and processes a first telecommunications signalling message (160) for the call to provide control and signalling messages (162, 163, 164, 165, 166) that identify the selection and transfer the control messages to the ATM internetworking multiplexers (110, 112, 114) that accepted the access connection for the call. The multiplexers (110, 112, 114) convert user information from the access connection into ATM cells for transmission over the virtual connection in accord with the control messages (162-166). An ATM cross connect system (120) operationally connected to the multiplexers (110, 112, 114) routes the ATM cells based on the virtual connection identified in the ATM cells. The narrowband switches (130, 132) provides the service to call based on the telecommunication signaling message.

L'invention concerne un système de télécommunications à large bande qui intègre les capacités des composants à large bande et celles des commutateurs de circuits classiques. Un processeur de signalisation (140) reçoit et traite un premier message de signalisation de télécommunication (160) en rapport avec l'appel pour fournir des messages de commande et de signalisation (162, 163, 164, 165, 166) qui identifient la sélection et transfèrent les messages de commande aux multiplexeurs d'interconnexion MTA (110, 112, 114) qui ont accepté la connexion d'accès pour l'appel. Les multiplexeurs (110, 112, 114) convertissent les informations d'utilisateur de la connexion d'accès en cellules MTA pour les transmettre au moyen de la connexion virtuelle conformément aux messages de commande (162-166). Un système de sous-répartition MTA (120) connecté de manière fonctionnelle aux multiplexeurs (110, 112, 114) achemine les cellules MTA sur la base de la connexion virtuelle identifiée dans les cellules MTA. Les commutateurs à bande étroite (130, 132) fournissent le service d'appel sur la base du message de signalisation de télécommunication.
