Abstract
A single 10/100/1000BT Ethernet network physical layer chip and a single transformer, both within a mobile computer, are employed to provide a network connection to the mobile computer either through a network connection interface within a docking station receiving the mobile computer, when the mobile computer is docked, or through a network connection interface within the mobile computer, when the mobile computer is not docked. Connection traces to the unused network connection interface have the characteristics of a small, unterminated stub, with any reflections handled by intrinsic echo cancellation during 1000BT operation and negligible during 10/100BT operation.
