Claim Text:
1. An energy efficient network communication device, comprising: a media access controller for outputting a transmission-end low power idle indication (TX-LPI indication) and receiving a reception-end low power idle indication (RX-LPI indication), including: a media independent interface including: the media independent transmission interface for generating a transmission-end low power idle signal (TX-LPI signal) according to the TX-LPI indication; and the media independent reception interface for generating the RX-LPI indication according to a reception-end low power idle signal (RX-LPI signal); and a physical layer circuit, electrically coupled to the media independent interface and several pairs of transmission lines, including: wherein the physical layer circuit uses at least one of the several pairs of transmission lines to send the transmission signal and receive the reception signal, and keeps at least another one of the several pairs of transmission lines unused, and after sending the transmission signal and/or receiving the RX-LPI signal, the physical layer circuit enters the LPI mode from an idle mode and stops the operation of some or all of the physical layer circuit to reduce power consumption.
