Abstract

Apparatus and method for simultaneously providing multiple telephone-type services to any/all POTS-type devices on a single wire pair at a user premises. The present invention provides for the ability to add separately addressable POTS devices on a single service loop. This can be accomplished in at least two ways: first by the use of a multipoint protocol or second by Frequency Division Multiplexing.

Claims (44)

1. A method comprising:

providing a first bi-directional voice service to a first device at a user premise over a subscriber line within a plain old telephone system (POTS) frequency band; and

providing, concurrently with the first bi-directional voice service, a second bi-directional voice service to a second device at the user premise identified by a unique address over the subscriber line within a frequency band that is higher than the POTS frequency band.

2. The method of claim 1 , further comprising:

communicating a data signal in the frequency band that is higher than the POTS frequency band on the subscriber line.

3. The method of claim 2 , wherein the data signal is communicated concurrently on the subscriber line.

4. The method of claim 1 , further comprising assigning the unique address to the second device.

5. The method of claim 1 , further comprising providing, concurrently with the second bi-directional voice service, a third bi-directional voice service in the frequency band that is higher than the POTS frequency band to a third device identified by another unique address.

6. A method comprising:

providing a first bi-directional voice service over a subscriber line within a plain old telephone system (POTS) frequency band; and

providing a plurality of services, including a second bi-directional voice service, over the subscriber line within a frequency band that is higher than the POTS frequency band,

wherein each of the plurality of services is separately identified by a unique address to a device at a user premise.

7. The method of claim 6 , wherein the plurality of services further includes at least one of an audio service, a video phone service, a digital phone service including a protocol for communicating voice over the Internet, a digital facsimile service, and an audio and visual data streaming service.

8. The method of claim 6 , further including the steps of:

assigning a first device identifier to a device receiving one of the plurality of services; and

assigning a second device identifier to a device receiving another one of the plurality of services, the second device identifier different than the first device identifier.

9. The method of claim 6 , further including the steps of:

assigning a first frequency band above the POTS band to a device receiving one of the plurality of services; and

assigning a second frequency band above the POTS band to a device receiving another one of the plurality of services, the second band different than the first band.

10. The method of claim 6 , further including the steps of:

assigning a first time slot to a device receiving one of the plurality of services; and

assigning a second time slot to another device receiving another one of the plurality of services, the second time slot different than the first time slot.

11. The method of claim 6 , wherein the voice service is provided concurrently with the plurality of services.

12. The method of claim 6 , wherein the plurality of services further includes a data signal in the frequency band that is higher than the POTS frequency band.

13. The method of claim 12 , wherein the data signal is provided concurrently with the second bi-directional voice service on the subscriber line.

14. The method of claim 6 , wherein the second bi-directional voice service is a digital phone service including a protocol for communicating voice over the Internet.

15. A system comprising:

means for providing a first bi-directional voice service to a first device at a user premise over a subscriber line within a plain old telephone system (POTS) frequency band; and

means for providing, concurrently with the first bi-directional voice service, a second bi-directional voice service to a second device at the user premise identified by a unique address over the subscriber line within a frequency band that is higher than the POTS frequency band.

16. The system of claim 15 , further comprising:

means for providing a third bi-directional voice service in the frequency band that is higher than the POTS frequency band to a third device identified by another unique address.

17. The system of claim 16 , wherein the second bi-directional voice service and the third bi-directional voice service are provided concurrently on the subscriber line.

18. A device comprising:

memory having stored thereon program code; and

a processor that is programmed by at least the program code to enable the device to:

provide a first bi-directional voice service to a first device at a user premise over a subscriber line within a plain old telephone system (POTS) frequency band; and

provide, concurrently with the first bi-directional voice service, a second bi-directional voice service to a second device at the user premise identified by an unique address over the subscriber line within a frequency band that is higher than the POTS frequency band.

19. The device of claim 18 , wherein the processor is further programmed by at least the program code to enable the device to:

provide a third bi-directional voice service in the frequency band that is higher than the POTS frequency band to a third device identified by another unique address.

20. The device of claim 19 , wherein the second bi-directional voice service and the third bi-directional voice service are provided concurrently on the subscriber line.

21. The device of claim 19 , wherein the processor is further programmed by at least the program code to enable the device to:

assign the unique address to the second device; and

assign the another unique address to the third device.

22. The device of claim 18 , wherein the processor is further programmed by at least the program code to enable the device to assign the unique address to the second device.
