And, the recorded communication channel information of the second connection unit is sent from the control unit to the first connection unit, and the communication channel information of the first connection unit is sent to the second connection unit. As a result, the first connection unit and the second connection unit are allowed to hold information communication by using their mutual communication channel information.
