Abstract

A method and system for providing a customer network with high speed access to a carrier network is provided. The system comprises an access device for providing a communication path for the customer network, a first concentrator device that is operable to establish a communication path with the carrier network, and a second concentrator device that is operable to establish a communication path with the carrier network. The access device is operable to receive data traffic from the customer network and to forward the data traffic within the system. The access device and the first concentrator device cooperate to form a first virtual channel for allowing data traffic to flow from the customer network to the carrier network and from the carrier network to the customer network and wherein the first virtual channel is the primary communication channel for the customer network. The access device and the second concentrator device cooperate to form a second virtual channel for allowing data traffic to flow from the customer network to the carrier network and from the carrier network to the customer network and wherein the second virtual channel is a backup communication channel for the customer network. The system is operable to switch the primary communication channel from the first virtual channel to the second virtual channel upon detection of a failure in the first virtual channel.
