摘要： Energy efficient Ethernet with a low power active idle transmission mode. A low power active idle transmission mode is defined for the transmission of idle signals during inter-packet gaps. The low power active idle transmission mode can provide energy savings in those instances that preclude the use of a low power idle mode and/or subrating to produce greater energy savings.

摘要： Communication devices coupled via a communication link may comprise physical layer devices that may be operable to determine presence of a received signal and to mitigate noise in the signal prior to processing and/or validating the signal. Analog and/or digital signal processing may be utilized to process the signal and/or mitigate noise in the signal. Noise mitigation may comprise near-end crosstalk cancelling and/or echo cancelling and/or may utilize local transmit signal information. Subsequent to noise mitigation, samples of the noise reduced signal may be accumulated and/or an average signal strength and/or average signal power level may be determined. The average signal strength and/or average signal power level may be compared to one or more thresholds which may be configurable and/or programmable.

摘要： A physical layer (PHY) in a network device may provide self-adapting power reduction based on monitoring of activity associated with an interface between the PHY and remaining components of the network device. The power management operations of the PHY may then be configured and/or adjusted based on that monitoring. The PHY may comprise an Ethernet PHY, which may support energy efficient Ethernet (EEE) features. The monitored interface may comprise a Media Independent Interface (MII) based interface. In instances where the monitored activity comprises outbound traffic, outbound data received via the interface may be buffered when at least one subcomponent of the PHY that is operable to support transmission of the outbound traffic is unavailable due to the power management operations. The buffering may be configured to last to allow sufficient time to reactivate the at least one subcomponent.

摘要： A system and method for loop timing update of energy efficient physical layer devices using subset communication techniques. During a quiet period during which a subset of communication channels are transitioned from an active mode to a low-power mode, circuitry in the active channel can be designed to track, on behalf of the inactive channels, the phase drift due to the frequency offset. This tracking of the frequency estimation error would reduce the time required to perform a timing update for the communication channels when transitioning back to the active mode.

摘要： A system and method for dynamic power control for energy efficient physical layer communication devices. Energy-efficiency features are continually being developed to conserve energy in links between such energy-efficient devices. These energy-efficient devices interoperate with many legacy devices that have already been deployed. In these links, energy savings can be produced by having a local receiver enter an energy saving state based upon the receipt of standard IDLE signals.
