Abstract
In a private branch exchange having an optimum route selecting function of selecting an optimum route by taking the destination, day of the week, time zone, permissive class of the extension terminal and the like into consideration when a call originating request from the extension terminal is generated, adequately processing dial number and outputting the same to an outgoing line so as to use the route, the route is selected by taking usage rates of the respective routes into consideration. Further, in the route selecting process, the route is selected by taking communication time (estimated value) into consideration. In an exchange system which is constructed by connecting plural private branch exchanges and in which, when an optimum route connected to one exchange is busy, dial number for permitting use of the optimum route is output via another exchange, the optimum route is not immediately selected via another exchange, but a substantially optimum route or routes which are substantially the same as the optimum route and connected to the given exchange are selected so that the dial number will be output from the given exchange with maximum possibility.
