ABSTRACT:
Hybrid fiber/coax networks employ the existing cable plant used for cable TV and transmit data signals in a frequency bandwidth above that which is used for cable TV. The present system used 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. 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.
