Abstract

A method includes identifying one or more second digital subscriber lines from one or more first digital subscriber lines based on historical performance data. The one or more second digital subscriber lines are identified based on degraded performance that is determined using first performance information for the one or more first digital subscriber lines. The method includes applying a line profile to the one or more second digital subscriber lines. The method includes storing second performance information associated with the one or more second digital subscriber lines. The method includes sending information to a remote computing device.

Claims

1. A method comprising:

identifying one or more second digital subscriber lines from one or more first digital subscriber lines based on historical performance data, wherein the one or more second digital subscriber lines are identified based on degraded performance that is determined using first performance information for the one or more first digital subscriber lines;

applying a line profile to the one or more second digital subscriber lines;

storing second performance information associated with the one or more second digital subscriber lines; and

sending information to a remote computing device, the information associated with the one or more second digital subscriber lines.

2. The method of claim 1, further comprising receiving the historical performance data from a database.

3. The method of claim 1, further comprising receiving the first performance information from a digital subscriber line access multiplexor.

4. The method of claim 1, wherein the line profile is a reduced speed profile.

5. The method of claim 1, wherein the line profile is a channel interleaved profile.

6. The method of claim 1, wherein the one or more first digital subscriber lines are supported by a digital subscriber line access multiplexor.

7. The method of claim 1, further comprising receiving the second performance information from a digital subscriber line access multiplexor.

8. The method of claim 1, further comprising sending an error message to a computing device, the error message indicating an error associated with applying the line profile.

9. The method of claim 1, wherein the information indicates performance of the one or more second digital subscriber lines before the line profile is applied and after the line profile is applied to the one or more second digital subscriber lines.

10. The method of claim 1, wherein the information is based on the second performance information.

11. A system comprising:

a processor; and

a memory accessible to the processor, the memory including instructions that, when executed by the processor, cause the processor to perform operations comprising;

identifying one or more second digital subscriber lines from one or more first digital subscriber lines based on historical performance data, wherein the one or more second digital subscriber lines are identified based on degraded performance that is determined using first performance information for the one or more first digital subscriber lines;

applying a line profile to the one or more second digital subscriber lines;

storing second performance information associated with the one or more second digital subscriber lines; and

sending information to a remote computing device, the information associated with the one or more second digital subscriber lines.

12. The system of claim 11, wherein applying the line profile includes sending a request to a digital subscriber line access multiplexor.

13. The system of claim 11, wherein the operations further comprise receiving the second performance information from a digital subscriber line access multiplexor.

14. The system of claim 13, wherein the second performance information is determined after the line profile is applied to the one or more second digital subscriber lines.

15. The system of claim 11, wherein at least one of the one or more second digital subscriber lines encountered an error associated with an adjustment process.

16. A system comprising:

a processor; and

a memory accessible to the processor, the memory including instructions that, when executed by the processor, cause the processor to perform operations comprising;

sending first performance information associated with one or more first digital subscriber lines that are associated with reduced performance, the reduced performance determined based on historical performance data;

receiving information identifying one or more second digital subscriber lines that have degraded performance, the one or more second digital subscriber lines identified from the one or more first digital subscriber lines based on the first performance information;

applying one or more line profiles to the one or more second digital subscriber lines; and

determining second performance information for the one or more second digital subscriber lines.

17. The system of claim 16, wherein the processor and the memory are included in a digital subscriber line access multiplexor.

18. The system of claim 16, further comprising sending an error message to a computing device for a particular digital subscriber line of the one or more second digital subscriber lines when application of the one or more line profiles to the one or more second digital subscriber lines results in an error.

19. The system of claim 16, wherein applying the one or more line profiles causes a particular line profile associated with the one or more second digital subscriber lines to change to a reduced speed profile.

20. The system of claim 16, wherein applying the one or more line profiles causes a particular line profile associated with the one or more second digital subscriber lines to change to a channel interleaved profile.
