Abstract

A system for connecting fiber optic telecommunications and video services to individual homes using a single twisted pair or coaxial cable line between the optical network unit and each service location. The single twisted pair or coaxial cable line connects to a broadband gateway located at the home, from which both telephone lines and other services may be delivered. Under this invention, the optical network units serve solely as connection and routing points for the drop lines, with telephone, video, and other services derived through the broadband gateway.

Claims

1. A method for communicating digital information between a fiber optic line and a service location for different services as electronic digital information at the service location, said method comprising the steps of:

receiving combined fiber optic digital information from the fiber optic lines and converting said combined fiber optic digital information into combined electronic digital information at a combining and distributing unit;

transmitting said combined electronic digital information to a gateway located at a service location; and

at the gateway, uncombining at least some of said combined electronic digital information and sending the combined and uncombined electronic digital information separately to a telephone and a customer provided network terminal at the service location.

2. The method in accordance with claim 1 further comprising the steps of:

combining within the gateway uncombined and combined electronic digital information from the telephone and the customer provided network terminal at the service location and transmitting the thus combined electronic digital information to the combining and distribution unit; and

at the combining and distributing unit, converting the combined electronic digital information from the service location into combined fiber optic digital information and transmitting the combined fiber optic digital information onto the fiber optic line.

3. The method in accordance with claim 1 wherein said combining comprises multiplexing.

4. The method in accordance with claim 1 wherein said uncombining comprises demultiplexing.

5. A system for communicating digital information between a fiber optic line and a service location for different services as electronic digital information at the service location, said system comprising:

a combining and distributing unit comprising means for receiving multiplexed fiber optic digital information from the fiber optic line, for converting said multiplexed fiber optic digital information into multiplexed electronic digital information, and for transmitting said multiplexed electronic digital information; and

a gateway at the service location coupled to said combining and distributing unit, said gateway comprising means for demultiplexing a portion of said multiplexed electronic digital information received from said combining and distributing unit, and for sending the demultiplexed and the multiplexed electronic digital information to different service units at the service location.

6. The system in accordance with claim 5 wherein said service units at the service location include a telephone for receiving the demultiplexed electronic digital information and a customer premises network for receiving multiplexed electronic digital information.
