ABSTRACT:
An auto-negotiation (AN) method for establishing a high speed link between first and second transmitting devices in a gigabit Ethernet using the 1000 Base-t standard includes transmitting and receiving a base page indicating a transmission capability between the first and second transmitting devices. A message page is transmitted and received that indicates a 1000 Mbps transmission capability between the first and second transmitting devices and a specific state. A first unformatted page is transmitted and received that indicates transmitting speeds and modes, and port types of the first and second transmitting devices. A null page is transmitted and received after the first unformatted page, upon determining a master and slave from among the first and second transmitting devices based upon the first unformatted page. A high speed link is established between the first and second transmitting devices and the AN method is terminated.
