To ensure an effective mechanism for disaster recovery, system migration and network enlargement, a communication system (FIG. 6) comprises a narrowband-to-broadband interface (300) having a plurality of network adaptors (302-306) interconnected to a switch (314-316) that provides access to a plurality of virtual channels (318-321) supported by a broadband network. The plurality of network adaptors (302-306) are also coupled to a plurality of trunks (308-312) that each support at least one of a plurality of different communication functions. At least two call servers (324-326) are independently coupled to the narrowband-to-broadband interface (300) and are arranged to control interconnection of trunks to virtual channels, while each of the at least two call servers is responsible for controlling interconnections of group of trunks that share a common communication function within each group. Communication system functionality is therefore separated between the at least two call servers.

Système permettant d'obtenir un mécanisme efficace de reprise après sinistre, de transition d'un système à un autre et d'agrandissement de réseau, soit un système de communication (fig. 6) comprenant une interface bande étroite-bande large (300) ayant plusieurs adaptateurs réseau (302-306) interconnectés à un commutateur (314-316) qui donne accès à plusieurs canaux virtuels (318-321) supportés par un réseau à large bande. Les adaptateurs réseau (302-306) sont aussi couplés à plusieurs circuits (308-312) qui supportent chacun au moins une des fonctions d'un groupe de fonctions de communication différentes. Au moins deux serveurs d'appels (324-326) sont couplés indépendamment à l'interface bande étroite-bande large (300) et sont disposés de façon à commander l'interconnexion de circuits avec les canaux virtuels, tandis que chaque serveur d'appels (au moins deux) est chargé de commander l'interconnexion de groupes de circuits qui partagent un fonction de communication dans chaque groupe. La fonction du système de communication est par conséquent séparée entre les serveurs d'appels (au moins deux).
