Abstract:
1. An autonegotiation circuit for Ethernet networks, comprising: a first device that communicates with a first media; a second device that communicates with a second media; and a Gigabit interface connector (GBIC) module that communicates with said first device over said first media and with said second device over said second media, wherein said GBIC provides autonegotiation between said first and second devices, wherein said first device includes a first GBIC interface including a transmitter and a receiver, said GBIC module includes a second GBIC interface with a transmitter and a receiver, said GBIC module includes a first copper interface with a transmitter and a receiver, and said second device includes a second copper interface with a transmitter and a receiver; wherein said transmitter of said first GBIC interface communicates with said receiver of said second GBIC interface and said receiver of said first GBIC interface communicates with said transmitter of said second GBIC interface, said transmitter of said first copper interface communicates with said receiver of said second copper interface and said receiver of said first copper interface communicates with said transmitter of said second copper interface, and said transmitters of said first and second GBIC interfaces transmit a first configuration ordered set; and wherein after said receiver of said second GBIC interface receives a second configuration ordered set from said transmitter of said first GBIC interface and said GBIC module stores in memory first configuration data of said first device that is contained in said second configuration ordered set, said transmitter of said first copper interface transmits a first fast link pulse (FLP) burst.
