Abstract
A network interconnection system has a plurality of input and output ports that are connected to different networks. An input interface connected to each of the input ports converts the input signal to an LCH packet signal when an input signal is not a MAC frame. A form of the LCH packet signal is identical to the MAC frame and a content of the LCH packet signal corresponding to a source address field of the MAC frame is set to all 0, which is inhibited in the MAC frame format. An output interface connected to each of the output ports converts the LCH packet signal to a signal conforming to a corresponding network when receiving an LCH packet signal as an output signal.
