Abstract

PURPOSE: To make it possible to equally receive the service by each request origin, by changing the precedence by use of the precedence deciding and selecting circuit, whenever the request is received by the transfer request input part.
CONSTITUTION: The switching information M11WM1n, M21WM2n...Mn1WMnn from the switching information control circuit 5 is input to the switching circuit 1, and the precedence deciding and selecting circuit 2 is changed in accordance with said switching information M11W1n...Mn1Wnn. Also, the selecting circuit 2 decides the precedence in order of the inputs T1...Tn from the switching circuit 1, and outputs the outputs S1...Sn (1 of them) in accordance with the sequence of request of the switching circuit 1. Moreover, the request sequence which has been changed is returned to its original sequence by inputting the outputs S1...Sn of the circuit 2, and the switching information M11WM1n...Mn1WMnn from the circuit 5, by the reversed switching circuit 3. And the service to the request origin is made equal by making it possible to change the precedence in the circuit 2 by the switching information of algorithm prepared by the circuit 5.
