<p>PROBLEM TO BE SOLVED: To connect a substitute terminal even when a first terminal cannot be connected to a designated second terminal of the connection destination by providing a control part which connects the first terminal to the substitute terminal in the case that the first terminal cannot be connected to the second terminal designated as the connection destination. SOLUTION: A band management table 112, a substitute terminal register table 113, and a control part 106 are provided. Data related to the band assigned to the second terminal is registered in the band management table 112. Another second terminal is registered as the substitute terminal of the second terminal in the substitute terminal register table 113. The control part 106 reads out the band assigned to the second terminal designated as the connection destination by the first terminal from the band management table 112 and decides whether the read band width is sufficient for connection or not; and if it is decided that the read band width is not sufficient, the substitute terminal read out from the substitute terminal register table 113 is connected to the first terminal.</p> |
