Abstract

Included are embodiments for back channel communication. At least one embodiment of a method includes receiving data at customer premises equipment and determining at least one error in the received data. Some embodiments include formatting the determined error for communication to a central office and sending the formatted error to the central office via a back channel.

Claims (32)

1. A method comprising:

receiving data at customer premises equipment;

determining at least one error in the received data;

formatting the determined error for communication to a central office; and

sending the formatted error to the central office via a back channel;

wherein the formatted error is sent between a first sync frame and a second sync frame of a discrete multitone (DMT) superframe.

2. The method of claim 1 , wherein the formatted error is sent via the back channel embodied as an embedded operational channel (EOC).

3. The method of claim 1 , wherein the formatted error is sent via the back channel embodied as a dedicated latency channel.

4. The method of claim 1 , further comprising utilizing a cyclic redundancy check (CRC) for error detection.

5. The method of claim 1 , wherein the error is sent to the central office for far end crosstalk (FEXT) error correction.

6. The method of claim 1 , further comprising utilizing a sync frame as a reference mechanism to identify specific data symbols for passing of the formatted error.

7. A system comprising:

a receiving component configured to receive data at customer premises equipment;

a determining component configured to determine at least one error in the received data;

a formatting component configured to format the determined error for communication to a central office; and

a sending component configured to send the formatted error to the central office via a back channel;

wherein the formatted error is sent between a first sync frame and a second sync frame of a discrete multitone (DMT) superframe.

8. The system of claim 7 , wherein the formatted error is sent via the back channel embodied as an embedded operational channel (EOC).

9. The system of claim 7 , wherein the formatted error is sent via the back channel embodied as a dedicated latency channel.

10. The system of claim 7 , further comprising utilizing a cyclic redundancy check (CRC) for error detection.

11. The system of claim 7 , wherein the error is sent to the central office for far end crosstalk (FEXT) error correction.

12. The system of claim 7 , further comprising a utilizing component configured to utilize a sync frame as a reference mechanism to identify specific data symbols for passing of the formatted error.

13. The system of claim 7 , wherein the system is embodied in a non-transitory computer readable medium.

14. A system comprising:

means for receiving data at customer premises equipment;

means for determining at least one error in the received data;

means for formatting the determined error for communication to a central office; and

means for sending the formatted error to the central office via a back channel;

wherein the formatted error is sent between a first sync frame and a second sync frame of a discrete multitone (DMT) superframe.

15. The system of claim 14 , wherein the formatted error is sent via the back channel embodied as an embedded operational channel (EOC).

16. The system of claim 14 , wherein the formatted error is sent via the back channel embodied as a dedicated latency channel.

17. The system of claim 14 , further comprising means for utilizing a sync frame as a reference mechanism to identify specific data symbols for passing of the formatted error.
