Abstract

Claims (59)

1. A method for delivering bursted native media data flows over an Ethernet physical layer between a head-end and an outstation, the method comprising the steps of:

operating a device in a default bypass mode at the outstation;

receiving a first command wherein the first command is one of a directed command and a multicast command to an address associated with the device for exchanging Ethernet frames with an Ethernet physical layer; and

receiving a second command wherein the second command is one of a multicast command and a directed command for exchanging bursted native media data flows with the Ethernet physical layer.

2. The method of claim 1 , the step of receiving the second command further comprising the steps of;

loading downstream bytes from the head-end into an input of the device; and

sending bursted native media data flows upstream to the head-end from an output of the device.

3. The method of claim 2 , wherein the input interfaces with a front end, wherein the bursted native media data flows are TDM data flows and the device is a TDM device.

4. The method of claim 1 , further comprising the step of:

receiving a third command to the address for exchanging Ethernet frames during a bypass mode wherein the third command is a directed command;

wherein the commands are one of pause signals and burst signals.

5. A method for delivering bursted native media data flows over an Ethernet physical layer between a head-end and an outstation, the method comprising the steps of:

operating a device in a default bypass mode at the head-end;

activating a signaling scheduler at the head-end for scheduling transmissions;

receiving a first command wherein the first command is one of a directed command and a multicast command to an address associated with the device for exchanging Ethernet frames with an Ethernet physical layer; and

receiving a second command wherein the second command is one of a multicast command and a directed command for exchanging bursted native media data flows with the Ethernet physical layer.

6. The method of claim 5 , wherein the step of receiving the second command further comprising the steps of:

loading upstream bytes from the outstation into an input of the device; and

sending bursted native media data flows downstream to the outstation from an output of the device.

7. The method of claim 6 , wherein the input interfaces with a front end, wherein the bursted native media data flows are TDM data flows and the device is a TDM device.

8. The method of claim 5 , further comprising the step of:

receiving a third command to the address for exchanging Ethernet frames during a bypass mode wherein the third command is a directed command;

wherein the commands are one of pause signals and burst signals.

9. A computer readable media storing code to perform the steps of the method recited in claim 1 .

10. A computer readable media storing code to perform the steps of the method recited in claim 5 .

11. A system for delivering bursted native media data flows over an Ethernet physical layer between a head-end and an outstation, the system comprising:

a device operating in a default bypass mode at the outstation; where the device receives a first command wherein the first command is one of a directed command and a multicast command to an address associated with the device for exchanging Ethernet frames; and

an Ethernet physical layer for exchanging bursted native media data flows when a second command wherein the second command is one of a multicast command and a directed command is received at the device;

wherein the device receives a third command to the address for exchanging Ethernet frames during a bypass mode wherein the third command is a directed command; wherein the commands are one of pause signals and burst signals.

12. The system of claim 11 , wherein the device further comprises:

an input for receiving downstream bytes from the head-end; and

an output for sending bursted native media data flows upstream to the head-end.

13. The system of claim 12 , wherein the input interfaces with a front end, wherein the bursted native media data flows are TDM data flows and the device is a TDM device.

14. The system of claim 11 , wherein the device receives a third command to the address for exchanging Ethernet frames during a bypass mode wherein the third command is a directed command; wherein the commands are one of pause signals and burst signals.

15. A system for delivering bursted native media data flows over an Ethernet physical layer between a head-end and an outstation, the system comprising:

a device operating in a default bypass mode at the head-end; and

a signaling scheduler at the head-end for scheduling transmissions;

wherein the device receives a first command wherein the first command is one of a directed command and a multicast command to an address associated with the device for exchanging Ethernet frames with the Ethernet physical layer and receives a second command wherein the second command is one of a multicast command and a directed command for exchanging bursted native media data flows with the Ethernet physical layer;

wherein the device receives a third command to the address for exchanging Ethernet frames during a bypass mode wherein the third command is a directed command; wherein the commands are one of pause signals and burst signals.

16. The system of claim 15 , wherein the device further comprises:

an input for receiving upstream bytes from the outstation; and

an output for sending bursted native media data flows downstream to the outstation.

17. The system of claim 16 , wherein the input interfaces with a front end, wherein the bursted native media data flows are TDM data flows and the device is a TDM device.

18. The system of claim 15 , wherein the device receives a third command to the address for exchanging Ethernet frames during a bypass mode wherein the third command is a directed command; wherein the commands are one of pause signals and burst signals.

19. An article of manufacture for delivering bursted native media data flows over an Ethernet physical layer between a head-end and an outstation, the article of manufacture comprising:

at least one processor readable media; and

instructions stored on the at least one media;
