Abstract

A method of selecting a profile of a digital communication line includes determining a first throughput value of the digital communication line, the first throughput value associated with a first profile and determined based at least in part on a count of code violations. The method includes determining a second throughput value of the digital communication line that is associated with a second profile, the second throughput value determined based on the count of code violations. The method includes identifying a selected profile that has a greater corresponding throughput value. The first throughput value is greater than the second throughput value when the count of code violations is less than a threshold and the first throughput value is smaller than the second throughput value when the count of code violations is greater than the threshold.

Claims

1. A method comprising:

determining a count of code violations associated with a digital subscriber line; and

selecting a particular profile of a plurality of profiles based on a comparison of the count of code violations to a threshold,

wherein the plurality of profiles includes at least a first profile associated with a first transmission speed and a second profile associated with a second transmission speed,

wherein the first profile is selected as the particular profile when the count of code violations is within a first range,

wherein the second profile is selected when the count of code violations is within a second range that is different from the first range,

wherein the first transmission speed is a non-interleaved transmission speed and the second transmission speed is an interleaved transmission speed,

wherein a first throughput value associated with the first profile is higher than a second throughput value associated with the second profile when the count of code violations is within the first range, and

wherein the first throughput value is lower than the second throughput value when the count of code violations is within the second range.

2. The method of claim 1, wherein the count of code violations is determined by counting data transmission anomalies associated with data transmitted over the digital subscriber line during a pre-determined time period.

3. The method of claim 2, wherein the data transmission anomalies include a signal to noise characteristic, an impulse noise characteristic, an interference characteristic, or a combination thereof.

4. The method of claim 1, wherein the first transmission speed is 1536 kbits per second, and wherein the second transmission speed is 768 kbits per second.

5. The method of claim 1, further comprising generating a graphical display that illustrates the first throughput value associated with the first profile, the second throughput value associated with the second profile, and the count of code violations.

6. The method of claim 5, wherein the graphical display illustrates a first set of data points for the first profile and a second set of data points for the second profile.

7. The method of claim 1, further comprising applying the selected particular profile to the digital subscriber line.

8. The method of claim 1, further comprising:

determining the first throughput value of the digital subscriber line based on the count of code violations, wherein the first throughput value comprises a first data packet transmission control protocol/internet protocol throughput value; and

determining the second throughput value of the digital subscriber line based on the count of code violations, wherein the second throughput value comprises a second data packet transmission control protocol/internet protocol throughput value, wherein the particular profile is selected based further on the first throughput value and the second throughput value.

9. The method of claim 1, wherein the count of code violations is determined by counting data transmission anomalies and wherein the data transmission anomalies include a bipolar violation, an excessive zeros error event, a frame synchronization bit error, or a combination thereof.

10. The method of claim 1, wherein the count of code violations is determined by counting data transmission anomalies and wherein the data transmission anomalies include at least two of a bipolar violation, an excessive zeros error event, a frame synchronization bit error, or a combination thereof.
