摘要： Fast retraining of communication parameters for a transceiver in a communication network. In one aspect, it is determined that the transceiver has lost the communication link for data communication, and the transceiver receives a signal providing a fast retraining sequence that updates transceiver parameters in order to reacquire the link for the data communication. The fast retraining sequence is performed in a reduced time relative to a full training sequence used for initializing the parameters for data communication by the transceiver.
