Abstract
An interactive system and method for communicating data over a network of twisted pair wiring that is in active use as a conductive path for telephone signals. A first channel is used for transmission of data from a signal interface to a transceiver. The data is made available to the signal interface from an external source of information. The transceiver communicates data in the reverse direction of a second channel. The transceiver can sendcontrol signals upstream to indicate which audio/video content is to be sent back. Information communicated in the reverse channel can be received as a light signal, with the light signal recreated at the opposite end of the link.
