Abstract
A DSL communication device wherein the state of component coefficients are saved in a memory of a DSL device so that at a later time, the DSL device may initiate a warm start activation sequence wherein the last known channel parameters are used to train the equalizer, significantly reducing the amount of equalizer training required by eliminating the requirement that the aforementioned coefficients be transferred between DSL devices.
