Using parameters for approval operation generated by the central processing unit, the terminal equipment and the central processing unit perform the approval operations of programs for terminal use held by each of them. Results of the approval operations are compared by the central processing unit. If they are in agreement with each other, the communication is permitted to be continued relative to the terminal equipment.
