Abstract

PURPOSE:To economize a circuit and to improve performance by transmitting special information when a subscriber's telephone set is brought into the called state. CONSTITUTION:When either a monitor device 2 or 3 detects an abnormality, a relay acts to bring the subscriber's telephone set 1 into the called state, and a subscriber line is switched to the side of an oscillator unit 4, thereby transmitting a dial tone. When a receiver unit 11 receives the dial tone, a marker 6 and a memory device 12 are activated. At this time, the model of the monitor device is transmitted from the marker 6, while the memory device 12 decides whether or not it is the subscriber of the automatic monitor and connection. If the subscriber is registered in the memory device 12, connecting destination telephone number information and monitor device model information of the subscriber are transmitted to the marker 6. If it is not registered, the special incoming call number and the monitor device of non-registered subscriber are transmitted.
