Abstract:
1. 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 represents a maximum attainable DSL speed, wherein the configuration parameter represents a maximum capable DSL speed, the DSL configuration parameter is computed prior to the reinitializing of the DSL modem, wherein determining the maximum capable DSL speed based on the first and the second data comprises determining a minimum in the first and the second data, wherein determining the maximum capable DSL speed based on the first and the second data further comprises multiplying a scale factor and the minimum in the first and the second data, and wherein the scale factor is selected based upon a number of data points in the second data.
