Abstract:
1. A method for networking in a first link partner that is coupled to a second link partner via a network cable, said network cable supporting a plurality of communication channels between said first and second link partners, the method comprising: transitioning said first link partner from an active state to a low power state, wherein during said active state the plurality of communication channels are each in an active mode, and during said low power state at least a first of the plurality of communication channels has transitioned from said active mode to a low power mode, wherein said first of the plurality of communication channels in said low power mode has a lower rate of communication relative to said first of the plurality of communication channels in said active mode; during said low power state, monitoring one or more parameters for one or more active mode communication channels, wherein said one or more parameters are used by one or more of an echo canceller, a far-end crosstalk canceller and a near-end crosstalk canceller in said first link partner; determining when to initiate a trigger for training parameters of at least said first of the plurality of communication channels in said low power mode based on said monitoring of said one or more parameters for said one or more active mode communication channels; and training said one or more parameters for at least said first of the plurality of communication channels in said low power mode upon an initiation of said trigger.
