A telecommunications network comprises a virtual transport server (VTS) for making network routing decisions and establishing call connections. Each VTS is interconnected to each signal transfer point in a common channel signaling (CCS)system associated with the network. Each VTS is also interconnected to at least one switch in a transmission network, such as an asynchronous transfer mode (ATM) switch. The VTS maintains routing tables identifying trunk groups associated with each central office switch in the network. During operation, an initial address message received from a signal transfer point in the VTS is processed and subsequently extended to an ATM switch so that a call connection can be established. Upon completion of the established call, the VTS releases resources associated with the ATM switch.
éseau de télécommunications comprenant un serveur de transport virtuel (VTS) pour la prise de décisions d'acheminement et l'établissement des communications. Chaque VTS est interconnecté à chaque point de transfert des signaux dans un système de signalisation par canal sémaphore (CCS) associé au réseau. Chaque VTS est également connecté à au moins un commutateur d'un réseau de transmission, par exemple un commutateur ATM (mode de transfert asynchrone). Le VTS tient des tables de routage identifiant les faisceaux de circuits associés à chaque commutateur de central du réseau. Pendant l'exploitation, un message initial d'adresse reçu par le VTS en provenance d'un point de transfert de signaux est traité puis transmis à un commutateur ATM pour qu'une communication puisse être établie. Lorsque la communication est établie, le VTS libère les ressources associées au commutateur ATM.
