ABSTRACT:
A signal interface is provided for coupling a network front end circuit to a network adapter circuit, wherein the network front end circuit communicates with a network. The signal interface comprises a plurality of input signal lines, each operable to conduct an input signal from the network front end circuit to the network adapter circuit. The signal interface further comprises a plurality of output signal lines, each operable to conduct an output signal from the network adapter circuit to the network front end circuit. Selected ones of the input and output signal lines are functional to support both a first and second network protocol on the same line. Further, only input signals are input on the selected input lines and only output signals are output on the selected output lines.
