Abstract
A method for fast link recovery for an Ethernet link is disclosed. The method includes detecting a drop in link quality and performing a first fast retrain sequence, including determining and exchanging THP coefficients based on the drop in link quality. If the performed fast retrain fails to recover the link, a data rate associated with the link is reduced, and a second fast retrain sequence performed.
