ABSTRACT:
Providing point to multi-point communication includes associating channels to endpoint nodes of a digital subscriber line, where each channel is associated with an endpoint node, and associating channel criteria to the endpoint nodes, where each channel criterion is associated with an endpoint node. Downstream packets are broadcast from a headend node to the endpoint nodes using the channels. Upstream packets transmitted from the endpoint nodes are received, where the upstream packets are multiplexed according to the channel criteria.
