Abstract

PURPOSE:To make a system report calling detection information, by writing the calling detection information in the first-in first-out memory by a scanning device, and sending out an interruption signal to a signal processing equipment immediately just after the write is finished. CONSTITUTION:When a signal has appeared in the circuit 6, the scanning unit 3 detects a status change from ''0'' to ''1'' by the hook-up of a subscriber's telephone set. The circuit number of detected calling and the fact of calling are written in the first-in first-out memory 2 through the write line 5, and immediately after that, an interruption signal is sent out to the signal processing equipment 1 through the interruption signal line 7. When the interruption signal has been received, the equipment 1 halts the software processing, reads the calling information through the read line 4 from the memory 2, and starts the unit of the program for receiving a selective signal from the circuit 6.
