Abstract
PURPOSE:To perform unmanned test of each terminal equipment, by installing a transmission starting section of the terminal equipment on an automatic tester. CONSTITUTION:Simultaneously when emergency terminal units 11-1n for medical treatment and an automatic tester 3 installed on the emergency center by using a circuit 2, a terminal transmission starting section 21 is installed on an automatic tester 3. A transmission trigger signal is automatically transmitted from this starting section 21 at every terminal. Then, emergency terminal units 11-1n receive this trigger signal to close the DC circuit in the same manner as automatic operation of transmission button and transmit the dial pulse of the terminal. After detecting a polarity reverse signal sent from the automatic tester 3, terminal information is automatically transmitted. Next, the automatic tester 3 receives this information by an information reception section 11 and the control section judges the data if they are good or not.
