Abstract

A system (10) for communicating information associated with one or more subscribers includes a connecting link (50). A first switching system (14) coupled to the connecting link (50) communicates remote voice signals (60) and remote data signals (62) using the connecting link (50). A second switching system (14) coupled to the connecting link (50) includes an interface (56) to receive the remote voice signals (60) and the remote data signals (62) using the connecting link (50). The second switching system (14) also includes subscriber line ports (17) for receiving local voice signals (52) and local data signals (54) from subscribers. The interface (56) of the second switching system (14) selectively communicates the highest priority available signals using an outgoing link, voice signals (52, 54) having higher priority than data signals (60, 62). In a more particular embodiment, the remote voice signals (60) may have higher priority than the local voice signals (52).

Claims

1. A system for communicating information associated with one or more subscribers, comprising:

a splitter coupled to a plurality of subscriber line ports to separate local data signals from local voice signals;

a connecting link;

a first switching system coupled to the connecting link to communicate remote voice signals and remote data signals using the connecting link;

a second switching system coupled to the connecting link and comprising;

a first processor coupled to the splitter to receive the local voice signals;

a second processor coupled to the splitter to receive the local data signals; and

an interface to receive the remote voice signals and remote data signals using the connecting link, and to receive local voice signals from the first processor and local data signals from the second processor, wherein local voice signals have a different priority than remote voice signals and local data signals have a different priority than remote data signals.

2. The system of claim 1, wherein remote voice signals have higher priority than local voice signals.

3. The system of claim 1, wherein the first and second switching systems are each operable to associate timestamps with remote and local voice signals, respectively, the second switching system being further operable to selectively communicate the oldest available voice signal according to its associated timestamp.

4. The system of claim 1, wherein remote data signals have higher priority than local data signals.

5. The system of claim 1, wherein the first and second switching systems are each operable to associate timestamps with remote and local data signals, respectively, the second switching system being further operable to selectively communicate the oldest available data signal according to its associated timestamp.

6. The system of claim 1, wherein the second switching system is operable to determine priorities among two data signals according to relative revenues associated with each data signal.

7. The system of claim 1, wherein the second switching system is operable to determine priorities among two data signals according to relative subscriber payments associated with each data signal.

8. The system of claim 1, wherein the second switching system is operable to determine priorities among two data signals according to recent local data traffic in the second switching system relative to payments received from subscribers associate with the second switching system.

9. The system of claim 1, wherein the outgoing link is a second connecting link coupling the second switching system to a third switching system.

10. The system of claim 1, wherein the outgoing link couples to a central office.

11. The system of claim 10, wherein the outgoing link comprises a wide area network (WAN) link and the connecting link has substantially the same bandwidth as the WAN link.

12. The system of claim 10, wherein the outgoing link comprises a local area network port.

13. The system of claim 1, wherein the first and second switching systems are operable to function as a single logical unit in communicating information between the subscribers and a central office.

14. A method of communicating information associated with one or more subscribers, comprising:

using a connecting link, communicating remote voice signals and remote data signals from a first switching system coupled to the connecting link;

receiving the remote voice signals and remote data signals at an interface of a second switching system coupled to the connecting link;

separating local data signals from local voice signals at a slitter coupled to a plurality of subscriber line ports;

receiving the local voice signals at a first processor and the local data signals at a second processor from the splitter;

communicating the local voice signals and local data signals from the first processor and the second processor to the interface; and

selectively communicating the highest priority available signal from the interface using an outgoing link, wherein local voice signals have a different priority than remote voice signals and local data signals have a different priority than remote data signals.

15. The method of claim 14, wherein remote voice signals have higher priority than local voice signals.

16. The method of claim 14, further comprising:

associating timestamps with remote and local voice signals at the first and second switching systems, respectively; and

selectively communicating the oldest available voice signal from the second switching system according to its associated timestamp.

17. The method of claim 14, wherein remote data signals have higher priority than local data signals.

18. The method of claim 14, further comprising:

associating timestamps with remote and local data signals at the first and second switching systems, respectively; and

selectively communicating the oldest available data signal from the second switching system according to its associated timestamp.

19. The method of claim 14, further comprising determining priorities among two data signals at the second switching system according to relative revenues associated with each data signal.

20. The method of claim 14, further comprising determining priorities among two data signals at the second switching system according to relative subscriber payments associated with each data signal.

21. The method of claim 14, further comprising determining priorities among two data signals at the second switching system according to recent local data traffic in the second switching system relative to payments received from subscribers associated with the second switching system.

22. The method of claim 14, wherein the outgoing link is a second connecting link coupling the second switching system to a third switching system.

23. The method of claim 14, wherein the outgoing link couples to a central office.

24. The method of claim 23, wherein the outgoing link comprises a wide area network (WAN) link and the connecting link has substantially the same bandwidth as the WAN link.

25. The method of claim 23, wherein the outgoing link comprises a local area network port.

26. The method of claim 14, wherein the first and second switching systems function as a single logical unit in communicating information between the subscribers and a central office.
