A method and system for communicating between a number of computers within a residence over an active telephone network, and for communicating data between a telephone exchange and the residence in a first data band concurrently with the computers communicating in a second data band over the telephone wiring network within the residence. A modem bridges communication in the first data band and the second data band enabling the computers to communicate with the telephone exchange, which may provide a data path to other computers, for instance over the Internet. In addition, signals such as video signals can be distributed within the residence in an additional high-frequency band making use of common circuitry for both data and video communication.
