Abstract
A physical layer (PHY) processor of a network interface device operates in a low power state in which a transceiver of the PHY processor device periodically does not transmit on a communication link during a plurality of quiet time slots. In response to determining a low signal-to-noise ratio (SNR) condition associated with the communication link, the PHY processor transitions to a link recovery state in which the transceiver continuously transmits idle symbols. In response to determining that the low SNR condition has ended, the PHY processor transitions from the link recovery state to the low power state.
