Patent ID: 7558315

Claim:
A method in a controller communicably attached with a Digital Subscriber Line (“DSL”) modem pair, comprising: collecting operational data from the DSL modem pair, wherein the operational data comprises current operational data and historical operational data, the historical operational data collected over a period of time from prior trainings or prior DSL line uses of the DSL modem pair and stored in a library; generating distributions over time of at least one performance-related parameter represented within the collected operational data; analyzing the generated distributions over time of the at least one performance related parameter, wherein the analysis indicates whether the at least one performance related parameter fails to meet a target value; generating a margin-related parameter set based on the analysis, such that when the margin-related parameter set is applied to the operation of the DSL modem pair, it reduces the likelihood of the performance-related parameter value not meeting the desired target value; and instructing the DSL modem pair to operate in accordance with the margin-related parameter set.
