Abstract
A network interface device includes lines having functions for transmitting and receiving a signal to and from a station via a connection port. A line reversal circuit reverses the functions of the lines. A controller directs the line reversal circuit to switch the functions of the lines on non-reception of a predetermined signal which is tested for at predetermined intervals. The predetermined signal includes a connection confirmation signal, which is a Normal Link Pulse defined in the IEEE 802.3 Standard.
