Methods and apparatus to determine digital subscriber line configuration parameters

A method comprising,

• obtaining first data representative of a current performance characteristic for a digital subscriber line (DSL) modem;
• obtaining second data representative of a historical performance characteristic for the DSL modem;
• computing, by a maintenance server, a configuration parameter using the first and the second data;
• and
• reinitializing the DSL modem with the computed DSL configuration parameter when the computed configuration parameter has a value different from a previous value of the configuration parameter, wherein the current performance characteristic value represents a count of receiver errors over a time period, and wherein the configuration parameter represents whether or not interleaving is enabled for a telephone line, and computing the configuration parameter based on the first and the second data comprises:
• determining a maximum in the first and the second data;
• and
• enabling interleaving for the telephone line if the maximum in the first and the second data is greater than a threshold.

An article of manufacture comprising a tangible storage medium excluding propagating signals and storing machine readable instructions that, when executed, cause a processor to:

• obtain first data representative of a current performance characteristic for a digital subscriber line (DSL) modem, wherein the current performance characteristic is a count of receiver errors over a time period;
• obtain second data representative of a historical performance characteristic of the DSL modem;
• compute a configuration parameter based on the first and second data by determining a maximum in the first and second data and enabling interleaving if the determined maximum is greater than a threshold, wherein the configuration parameter represents interleaving enablement;
• and
• when the computed configuration parameter has a value different from a previous value of the configuration parameter, reinitialize the DSL modem with the computed configuration parameter, wherein the tangible storage medium excludes propagating signals.
