Abstract
When setting a branch route in a three-stage cross-connect switch system having a non-blocking three-stage Clos switch configuration having input stage switches, intermediate stage switches and output stage switches, the output stage switches, the intermediate stage switches and the input stage switches are searched first, second and third, respectively, for points of branching connection with existing routes in order to avoid, as far as practicable, the use of the output terminals of input stage switches having the same switch number. The blocking of any route setting request newly emerging for one-to-one connection or branching connection can be thereby restrained.
