Abstract
The present system uses point-to-point data links between intelligent network elements located in the feeder/distribution network to provide reliable, secure, bi-directional broadband access. Digital signals are terminated at the intelligent network elements, switched and regenerated for transmission across additional upstream or downstream data links as needed to connect a home to a headend or router. The intelligent network elements can be co-located with or replace the standard network elements to take advantage of existing network configurations. A tree-and-branch network architecture is therefore established in which each intelligent network element is assigned a routing ID employed in the point-to-point transmissions while leaving legacy analog signals unimpeded. In this manner, the data links are made over relatively short runs of coax cable, which can provide greater bandwidth than the typical end-to-end feeder/distribution connection between a home and the headend or optical network unit.
