Abstract

A system and method for providing a minimum burst duration in accordance with a regional standard and/or requirement. One embodiment comprises a first interface (204) configured to receive data to be communicated, a memory (208) configured to store a value corresponding to a regional minimum duration, a processor (202) configured to generate a frame, configured to compare a duration of the generated frame with the regional minimum duration, configured to add at least one padding symbol to the generated frame to generate a second frame, the second frame having a duration at least equal to the regional minimum duration, and a second interface (206) configured to communicate the second frame onto a communication channel.

Claims

1. A method for extending the duration of a communicated frame, the method comprising:

receiving configuration input that corresponds to a minimum burst transmission time for crosstalk detection;

setting a specified minimum duration of time based on the configuration input;

generating a frame;

comparing the specified minimum duration of time with a duration of time associated with the generated frame;

adding at least one padding symbol to the generated frame such that a duration of a second frame is increased at least to a duration corresponding to at least the specified minimum duration; and

communicating the second frame.

2. The method of claim 1, further comprising adding a last sequence of symbols, the sequence indicating an end of the second frame.

3. The method of claim 1, wherein adding the padding symbols further comprises varying the number of symbols added to the generated frame.

4. The method of claim 1, further comprising determining a duration difference between the duration of the generated frame and the minimum duration.

5. The method of claim 4, further comprising determining the number of padding symbols, wherein the determined number of padding symbols corresponds to the determined duration difference.

6. The method of claim 1, further comprising specifying the minimum duration.

7. The method of claim 6, further comprising changing the specified minimum duration to a second minimum duration, wherein the number of padding symbols corresponds to the second minimum duration.

8. The method of claim 1, wherein the configuration input is received remotely.

9. A system which extends the duration of a frame to be communicated, comprising:

a first interface configured to receive data to be communicated;

a processor configured to receive configuration input that corresponds to a minimum burst transmission time for crosstalk detection, configured to set a specified minimum duration of time based on the configuration input, configured to generate a frame to be communicated, configured to compare the specified minimum duration of time with a duration of time associated with the generated frame, and configured to add at least one padding symbol to the generated frame to generate a second frame, the second frame having a duration at least equal to the minimum duration;

a memory configured to store the specified minimum duration of time;

a second interface configured to communicate the second frame onto a communication channel.

10. The system of claim 9, wherein the memory further comprises a specified minimum duration corresponding to the specified regional minimum duration.

11. The system of claim 9, wherein the memory further comprises a regional padding symbol value corresponding to the specified regional minimum duration.

12. The system of claim 9, wherein the system comprises at least one selected from a group consisting of a computer terminal 116, a digital telephone device, an Internet television device, an audio device, a multimedia device, a facsimile (fax) device, a graphic device, a high-speed Internet device, a high-speed local access network (LAN) device, an Internet telephone device, a stereo/audio device, a digital television device, a digital video cassette recorder device, a utility meter device, a home management device and a security device.

13. The system of claim 9, wherein the specified minimum duration is a ANSI T1.417 minimum transmission time.

14. The system of claim 9, wherein the specified minimum duration is configurable.

15. The system of claim 9, wherein the processor is configured to determine a number of padding symbols based on the symbol rate, and wherein the processor is configured to add the number of padding symbols to the generated frame to generate a second frame.

16. The system of claim 9, wherein the data to be communicated is an ATM cell.

17. The system of claim 16, wherein the ATM cell is a header only cell.

18. The system of claim 9, wherein the at least one padding symbol includes a barker sequence.

19. The system of claim 9, wherein the at least one padding symbol includes a delineation of an end-of-pad.

20. The system of claim 9, wherein the system is configured to have the configuration input received remotely.

21. A system which extends the duration of a frame to be communicated, comprising:

means for receiving configuration input that corresponds to a minimum burst transmission time for crosstalk detection;

means for setting a specified minimum duration of time based on the configuration input;

means for receiving data to be communicated;

means for generating a frame;

means for comparing the specified minimum burst duration of time with a burst duration of time associated with the generated frame;

means for adding at least one padding symbol to the generated frame such that a burst duration of a second frame is increased at least to a predetermined burst duration corresponding to at least the specified minimum burst duration; and

means for communicating the second frame.

22. The system of claim 21, wherein the means for receiving configuration input receives the configuration input remotely.

23. A computer-readable storage medium encoded thereon a computer program for extending the duration of a communicated frame, the program when executed performs the steps of:

receiving configuration input that corresponds to a minimum burst transmission time for crosstalk detection;

setting a specified minimum duration of time based on the configuration input;

receiving a data to be communicated;

generating a frame;

comparing the specified minimum duration with a duration of time associated with the generated frame;

adding at least one padding symbol to the generated frame such that a duration of a second frame is increased at least to a predetermined duration corresponding to at least the specified minimum duration; and

communicating the second frame.

24. The computer readable storage medium of claim 23, wherein the configuration input is received remotely.
