OG exemplary drawing
AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
The patentability of claim 10 is confirmed.
Claims 1-9 and 11-17 were not reexamined.
10. A broadband local area network for transmitting modulated signals using coaxial cable building wiring containing a plurality of branches comprising:
a filter located at the point of entry of the building wiring that rejects network signals originating in the building wiring such that the rejected network signals do not pass through the filter, but rather are reflected by the filter back into all branches of the building wiring;
at least one signal splitter;
a plurality of terminal devices connected to the wiring branches, each terminal device capable of communicating with other terminal devices the reflected signal path created by the filter, wherein the terminal devices perform equalization on the received signal that restores a flat frequency response to overcome communication channel impairments caused by the reflected signals.
