Abstract

Disclosed is a method that enables a Fast Ethernet device to switch to a 10 Mb/s operating mode during link disconnections, and to switch back to a NWAY-enabled mode once a physical link is detected. The disclosed method can be implemented automatically by hardware, or through software intervention. Benefits include a decrease in power consumption by approximately 40%.
