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. As this cable plant was deployed in a tree and branch
topology, data transmissions may be susceptible to noise, variable
transmission loss and frequency dispersion, particularly in the upstream
direction. Further, due to the tree and branch topology, homes at the far
end of the network experience much greater loss than do the homes that
are near to the headend/ONU. The present system, which 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. The standard network
elements can be selectively replaced by the intelligent network elements
in an incremental approach. 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.
