PURPOSE:To set an optimum detour condition even if an employment of an exchange network is changed by setting a distribution with respect to plural directions of callings to a predetermined station at a predetermined ratio and changing said ratio. CONSTITUTION:A central control unit 9, for instance, every time a calling having a receiving station of B station comes, refers to a calling number a71 to which '1' is added, when the calling number is a71='0'-'6', a direction path a51 is selected, and when the calling number a71='7'-'9', a direction path a52 is selected. Accordingly, a calling direction path a51 having a receiving station of B station is 70% in distribution and a calling direction path a52 is 30% in distribution. Since a direction path a5 corresponding to the calling number a7 in this calling number direction path table 86 can be optionally changed by an external designation, by designate the direction paths a51, a52 newly, a change of the distribution can be done easily. |
