ROUTE PREPARING LOGIC MEANS FOR COMMUICATION SWITCHING DEVICE

摘要

PURPOSE: To perform application to a large switching element and to set the route of information transmission by many possible routes in a route setting logic means for the switching element of a self route setting multi-stage switching circuit network for transferring information corresponding to the route setting function of the route setting logic means from plural entrances to plural exits by the switching element. CONSTITUTION: The switching elements are provided with three or more exits and the information is related to a self route setting tag SRT including a route setting control code RCC used by this route setting logic means RL so as to select one of the route setting functions RS, DI, PH and ES executed in the respective switching elements. The respective values of the route setting control code RCC identify a specified transmission pattern constituted of the predetermined sequence of the route setting function to be executed by the switching element.
