Interface for upgrading serial backplane application from ethernet to gigabit ethernet

摘要

An interface device having a plurality of ports with a plurality of speed configurations for a serial backplane with 2-pair copper transmission lines, has a plurality of high speed Ethernet ports and a plurality of Gigabit Ethernet ports. A switch mechanism for selecting between the high speed Ethernet ports and the Gigabit Ethernet ports will connect the selected port to the serial backplane via the 2-pair copper transmission lines.
