Patent ID: 7653015

Claim:
A device for coupling signals between first and second coaxial cables, the first coaxial cable being connected to carry a first bi-directional digital data signal in a first digital data frequency band, and the second coaxial cable being connected to carry a second bi-directional digital data signal in a second digital data frequency band, and each of the coaxial cables being connected to carry, multiplexed with the respective digital data signal, an analog video signal in an analog video signal frequency band distinct from each of the first and second digital data frequency bands, said device comprising: a first coaxial connector connectable to the first coaxial cable; a second coaxial connector connectable to the second coaxial cable; a first filter coupled between said first and second coaxial connectors and operative for substantially passing only signals in the analog video signal frequency band for passing the analog video signals between the first and second coaxial cables; a second filter coupled to said first coaxial connector and operative for substantially passing only signals in the first digital data frequency band; a first coaxial cable modem coupled to said second filter for conducting the first bi-directional digital data signal over the first coaxial cable; a third filter coupled to said second coaxial connector and operative for substantially passing only signals in the second digital data frequency band; a second coaxial cable modem coupled to said third filter for conducting the second bi-directional digital data signal over the second coaxial cable; a power port connectable to receive a power signal from a power signal source; a power supply coupled between said power port and said first coaxial cable modem for powering said first coaxial cable modem from the power signal; and a single enclosure housing said filters, said power supply, said modems and said connectors, wherein: said first and second coaxial cable modems are coupled to each other for passing digital data between the first and second coaxial cables; and said device is addressable in a local area network.
