PURPOSE:To secure the protection of a file by limiting a subscriber number able to be in incoming call connection for each exchange line and deciding a file accessible for each line. CONSTITUTION:When an incoming request reaches an information processor 1 from a terminal equipment 10 through an exchanger network 9, the incoming call request is accepted by an incoming request reception means 2 and a subscriber number table extraction means 3 is started. The subscriber number table extraction means 3 uses a line name requesting an incoming call as a keyboard to seek a line name coincident with the line name of a line definition table 7. A subscriber number discrimination means 4 seeks a number coincident with a subscriber number of a subscriber number table 8 extracted by the subscriber number table extraction means 3 based on the subscriber number obtained at the arrival of a call by the subscriber number table search processing. When the number is not registered, an incoming call reject means 6 is started and the reply of the incoming call reject is sent to the terminal equipment 10. |
