1. A method comprising
obtaining first data representative of a current digital subscriber line (DSL) performance characteristic;
collecting second data representative of historical values of the DSL performance characteristic; and
determining, by a communication device, a DSL configuration parameter based on the first and the second data, wherein the DSL performance characteristic is a maximum attainable DSL speed; the DSL configuration parameter represents a maximum capable DSL speed, and 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, and 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
configuring a communication device associated with the current DSL performance characteristic based on the maximum capable DSL speed.
