Abstract

A method and system for distributing broadband digital and telephone signals arriving at a subscriber'"'"'s home simultaneously over existing in-house four wire quad cable. The combined telephone and broadband signals entering the house are split upon entering the house and the broadband signals are converted to a locally generated broadband digital signal whose power spectral density is not distorted by recovery of the telephone signal, such as a 10Base-T signal. The locally generated combined broadband digital signals and telephone signals are distributed to broadband transceivers where the telephone signals and broadband digital signals are applied to telephones and broadband service termination devices, respectively.

Claims

1. A method for simultaneously distributing within a service location narrowband and broadband signals present at the service location, the distribution within the service location being over in-house four wire cable to different termination devices within the service location, said different devices including at least one telephone and at least one broadband service termination device, said method comprising the steps of:

in response to the broadband signals generating within the service location broadband digital signals operating at frequencies greater than 1,000,000 HZ (1 MHz);

combining said narrowband and said broadband digital signals at a first broadband transceiver within the service location; and

uncombining said narrowband and said broadband digital signals at a second broadband transceiver within the service location; and

applying within the service location the narrowband and broadband digital signals egressing the second broadband transceiver separately to the appropriate termination devices over the in-house four wire cable.

2. The method according to claim 1 further comprising the step of repeating said combining, uncombining, and applying steps until the narrowband and broadband digital signals reach each termination device within the service location.

3. The method according to claim 1 wherein said combining step comprises frequency division multiplexing.

4. The method according to claim 1 wherein said uncombining step comprises frequency division demultiplexing.

5. The method according to claim 4 wherein said telephone and broadband signals present at the service location are received at the service location over a twisted wire pair from a central office, said method further comprising the step of receiving and separating within the service location the narrow-band and broadband signals received from the central office.

6. The method according to claim 5 wherein the narrowband and broadband signals are received at the service location over an asymmetric;

digital subscriber line.

7. The method according to claim 5 further comprising the step of repeating said combining, uncombining, and applying steps until the narowband ands broadband digital signals reach each termination device with the service location.

8. A system for simultaneously transmitting within a service location telephone and broadband signals present at the service location, said signals being distributed through in-house four wire cabling to different termination devices within the service location, said different termination devices including at least a telephone and a broadband service termination device, said system comprising:

means within the Service location for receiving said broadband signals and for locally generating broadband digital signals operating at frequencies greater than 1,000,00 Hz (1 MHz);

at least one first transceiver within the service location for combining said telephone signals and said broadband digital signals from said receiving and generating means and for transmitting the combined signals over the in-house four wire cabling; and

at least one second transceiver within the service location for separating said broadband digital signals and said telephone signals and for applying said telephone signals to a telephone and said broadband digital signals to a broadband service termination device.

9. The system in accordance with claim 8 wherein said telephone and broadband signals present at the service location are received from a central office over a twisted wire pair between the central office and the service location, said system further comprising:

splitter means at the subscriber location for separating said broadband signals and said telephone signals received from the central office, said splitter means being connected both to said means for receiving said broadband signals and for locally generating said broadband digital signals and to said at least one first transceiver means.

10. The system in accordance with claim 9 wherein said broadband signals received from the central office are asymmetric digital subscriber line (ASDL) signals.

11. A system in accordance with claim 9 further comprising means connected to said splitter means for directly applying said telephone signals to a second telephone.

12. A system in accordance with claim 9 further comprising a plurality of first transceivers for combining said telephone signals from said splitter means and said broadband digital signals and transmitting the combined signals over different in-house four wire cabling and a plurality of said second transceivers for applying said telephone signals to a plurality of telephones and said broadband digital signals to a plurality of broadband service termination devices.

13. A system in accordance with claim 8 further comprising means connected to said means for locally generating the broadband digital signals for directly applying said broadband digital signals to a second broadband service termination device.

14. A system in accordance with claim 8 wherein the locally generated broadband digital signal is a 10Base-T signal.

15. A system in accordance with claim 8 wherein said means for locally generating comprises a broadband hub and said hub and cabling are configured in a star topology with said hub at the center of the star.
