Abstract
A system includes a broadcast overlay network including a ring topology. The ring topology includes a first network ring and a second network ring that is coupled to the first network ring via at least one cross-connect element. The ring topology is adapted to carry broadcast traffic from a network. The system also includes a digital subscriber line access multiplexer (DSLAM) having a line interface and a network interface. The network interface is in communication with the broadcast overlay network via the second network ring. The DSLAM is adapted to receive a request for a particular video channel from a customer premise via the line interface and to deliver the particular video channel from the network interface to the line interface.
