ABSTRACT:
A transmitting-receiving unit or a set of upper rank transmitting-receiving units and lower rank transmitting-receiving units are provided, and one or a plurality of circuits selected by a circuit selective switch unit from among many circuits are connected to the transmitting-receiving unit or the set. As a result, the burden of the control unit provided in the communication device is reduced. The maintenance of a route table which is used in transmitting packets from the highest rank station to the lowest rank station via other communication devices is made unnecessary by transferring the route table in order from the highest rank stations to the lowest rank stations.
