Abstract
A system and method for processing wake-up signals during a sleep mode of a computer in a communications network to wake up sleeping components of the computer. The system includes an extended PHY (physical layer) device for receiving wake-up signals from a network medium, converting the wake-up signals into an additionally-encoded data packet, and generating a standardized wake-up packet based on the additionally-encoded data packet. The system also includes a MAC (media access controller) device, coupled to the extended PHY device, for receiving the standardized wake-up packet and generating a wake-up notification signal in response to the standardized wake-up packet to wake up the sleeping to components of the computer.
