Abstract
The present invention is related to a transit trunk subnetwork system which is configured to expand the existing capacity for bearer traffic in telephone networks. The invention incorporates an asynchronous transfer mode subnetwork which is interfaced directly with existing local exchange end offices, access tandems, or combinations thereof. A signal controller is utilized to direct signal messaging across the asynchronous transfer mode subnetwork to set up the movement of bearer traffic across the subnetwork. A network manager is also utilized to control bandwidth availability at the interfaces with the asynchronous transfer mode subnetwork.
