Back channel communication
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.
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.
