<p>PROBLEM TO BE SOLVED: To solve the problem that a cross point switch is un-practicable about a large quantity of N because the cross point switch having N pieces of a well-known port requires connections of N2 pieces. SOLUTION: Each module of switching equipment for data transfer including connection link 13A, 13B, 13C and 13D in which each link has capacity to transfer data, and a plurality of modules 12 and 32 to communicate with this, includes a data port selector which can combine the data port in the modules 12 and 32 selectively in order to transfer data through at least one connection link of the one or more data ports 16A, 16B, 16C and 16D where each port has the capacity to transfer the data, and a data port selector with the capacity selectively combining with the data port in the modules 12 and 32 in order to receive the data through at least one connection linking.</p> |
