  • Patent number: 5572347
    Abstract: Switched video broadband service and narrowband telecommunications service are integrated and provided directly to subscribers. A plurality of video channels are provided to a central office by a video service provider, and said video channels are transmitted to a remote terminal using standard FM video supertrunks. At the remote terminal, video channels selected by a group of subscribers are frequency-division multiplexed with baseband signals of narrowband telecommunications service and are transmitted over a single fiber to an optical network unit adjacent the living units of the group of subscribers. The subscriber selected channels are then demultiplexed and provided to the living units via coaxial drops, along with the narrowband telephone service provided on twisted pairs. Channel requests from the group of subscribers are combined and transmitted upstream in a single narrowband video control channel.
