<<Problems to be Solved by the Invention>> However, as shown in FIG. 8, in order to provide the function of a T-switch using a D-switch OS, it was necessary to use two D-switch OSs. In addition, as shown in FIG. 9, in the R switch Rs, ports 2 and 4 are not coupled in position A, and ports 1 and 3 are not coupled in position C; Configuration is not realized. Therefore, in order to improve the function of the ■ switch, the R switch Rs should be set to 211 as shown in Figure 8.
