Abstract

A communications network is disclosed and includes a broadband communication line having a first derived voice channel and a second derived voice channel, wherein the first and second derived voice channels are established as a function of an available bandwidth associated with the broadband communication line. The communication network further includes a residential gateway in communication with the broadband communication line. The residential gateway includes a switch, a network interface device in communication with the switch, and wherein the switch is configured to select at least one of the first or second derived voice channels for voice communication over the broadband communication line as a function of the available bandwidth.

Claims

1. A communications network comprising:

a broadband communication line comprising;

a first derived voice channel; and

a second derived voice channel;

wherein the first and second derived voice channels are established as a function of an available bandwidth associated with the broadband communication line; and

a residential gateway in communication with the broadband communication line, the residential gateway comprising;

a switch;

a network interface device in communication with the switch; and

wherein the switch is configured to select at least one of the first or second derived voice channels for voice communication over the broadband communication line as a function of the available bandwidth.

2. The network of claim 1 further comprising an ATM (asynchronous transfer mode) network, the ATM network in communication with the residential gateway via the network interface device.

3. The network of claim 2 further comprising a telephony network, the telephony network in communication with the residential gateway via the network interface device.

4. The network of claim 1, wherein the residential gateway is configured to communicate with a local area network via the broadband communication line.

5. The network of claim 1, wherein the broadband communication line is configured to carry at least one digital voice communication and at least one digital data communication.

6. The network of claim 1, wherein the network interface device is configured for communications with the broadband communication line via a broadband cable connection.

7. The network of claim 1, wherein the network interface device is configured for communications with the broadband communication line via a broadband digital subscriber line connection.

8. The network of claim 1, wherein the network interface device is configured to receive a video signal from a television service provider selected from the group consisting of:

a cable provider and a satellite provider.

9. A communications network composing:

a broadband communication service provided by a cable connection, the broadband communication service comprising;

a plurality of derived voice channels;

wherein the plurality of derived voice channels are provided based on an available bandwidth associated with the broadband communication service; and

a residential gateway comprising;

a router;

a network interface device in communication with the router; and

wherein the router is configured to select at least one of the plurality of derived voice channels for voice communication over the cable connection as a function of the available bandwidth.

10. The network of claim 9 further comprising an (asynchronous transfer mode) ATM network, the ATM network in communication with the residential gateway via the network interface device.

11. The network of claim 10 further comprising a telephony network, the telephony network in communication with the residential gateway via the network interface device.

12. The network of claim 9, wherein the residential gateway is configured to communicate with a local area network via the router.

13. The network of claim 9, wherein the cable connection is configured to carry at least one digital voice communication and at least one digital data communication.

14. The network of claim 9, wherein the cable connection is provided via a broadband digital subscriber line connection.

15. The network of claim 9, wherein the network interface device is configured to receive a video signal from the cable connection.

16. A method of communicating via a network comprising:

establishing a broadband communication service on a cable connection, wherein establishing the broadband communication service comprises;

configuring a first derived voice channel, wherein the first derived voice channel is further configured to cooperate with a residential gateway; and

configuring a second derived voice channel, wherein the second derived voice channel is further configured to cooperate with the residential gateway;

wherein the first and second derived voice channels are defined based on an available bandwidth associated with the broadband communication service; and

configuring the residential gateway, wherein configuring the residential gateway comprises;

coupling a network interface device to a router to establish communications therewith; and

selecting between at least one of the first or second derived voice channels for voice communications over the cable connection, wherein the at least one of the first or second derived voice channels is selected as a function of the available bandwidth.

17. The method of claim 16 further comprising:

communicatively coupling an (asynchronous transfer mode) ATM network to the residential gateway via the network interface device.

18. The method of claim 17 further comprising:

communicatively coupling a telephony network to the residential gateway via the network interface device.

19. The method of claim 16, wherein establishing the broadband communication service includes establishing at least one digital voice communication and at least one digital data communication.

20. The method of claim 16, wherein coupling the network interface device includes configuring the network interface device to receive a video signal from the cable connection.
