Abstract
A virtual circuit (PVC) to switched virtual circuit (SVC) conversion system and method are used for communication across SVC in parallel with VCs or in place of VCs set up to other sites on a network when communication problems exist such as congestion, node-to-node failures or any other instances in which increased bandwidth is needed or service pricing justifies it. The VC to SVC conversion system is used in a communications access device to allow Carriers providing SVC service to avoid having to upgrade or replace the customer's existing premises equipment to support SVCs. The system comprises logic which maps a VC to an SVC configured by the user during configuration, based on the VC address contained in the data link control identification in the frame layout of the data. This logic exists in the memory of the communications access device and is executed on a processor which may or may not be located inside the communications access device which controls a communications switch in accordance with criteria from the network management system. Use of the present invention will increase efficiency and cost effectiveness of communications access.
