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.
