Abstract: An adaptive transmission line impedance matching device and method are disclosed. The device and method can be used, for example, in xDSL and home phone line network applications. The adaptive impedance matching device comprises a signal transmission section, a signal receiving section, a variable impedance matching network and a signal analysis section. The signal receiving section is operable to receive signal information transmitted across a transmission line. The signal analysis section is then operable to calculate a proper impedance match based upon the signal information and to adjust the variable impedance matching network according to the calculated impedance match. The device and method are robust enough, for example, to account for dynamic mismatches when telephone sets are taken off-hook during digital (e.g., xDSL) network operation.

Abstract: A method and system for selecting a frequency for communication within a premises network are disclosed that offer significant operational advantages. According to one aspect of the present invention, a system for selecting a frequency for communication within a premises network may include a telephone line interface, a transceiver, and a logic/control unit coupled to both the telephone line interface and the transceiver. The telephone line interface may be operable to couple to a premises network. In some embodiments, the logic/control unit may be operable to select a first channel. The first channel may correspond to a first frequency over which communications may be sent from the transceiver to other devices within the premises network.

Abstract: A system and method for distributing power over a premises network is provided. The system comprises a power receiving module operable to be coupled to a premises network located in a user site. A power source module is operable to be coupled to the premises network and a power supply. The power source module is operable to receive electrical power from the power supply and provide electrical power over the premises network such that the power is contained within the premises network.

Abstract: A method and system interface a digital data stream having at least one telephony data set with a telephony network, such as a single twisted wire pair telephony network installed in a residence or business. The telephony data set is converted to a telephony signal for use by conventional telephony devices, such as telephones, and is transmitted through the telephony network in a telephony network band. The telephony network band can be located outside of the voiceband to avoid interference with central office signals. Plural data telephony data sets can each provide a telephony signal directed to one or more telephony devices associated with the telephony network. Telephone control modules interfaced associated with the telephony devices can translate telephony signals from the telephony network band to the voiceband for use by the associated telephony devices. The method and system can support plural simultaneous telephony communications through a single twisted pair or other telephony network.
