Abstract
A system and method for coupling multiple home networks includes a first copper wire network, a second copper wire network, and a high pass coupler disposed between the first and second copper wire networks. The high pass coupler is configured to transfer data signals between the first and second copper wire networks, the data signals having frequencies greater than a maximum plain old telephone service signal frequency. Further, the high pass coupler is configured to prevent cross-talk of plain old telephone service, or voice-band, signals between the first and second copper wire networks. The data signals transferred typically include signals in accordance with the Home Phoneline Networking Alliance standard, and may also include broadband Internet access signals. In one embodiment, the high pass coupler is implemented in a residential gateway device. In another embodiment, the high pass coupler is implemented in a network coupler that couples the copper wire networks while maintaining access points to the first and second copper wire networks.
