Abstract

PURPOSE:To enable the calling side to confirm the talking possible situation without adding any external unit, by securing an automatic delay of the answer from the called terminal equipment for the necessary time and then originating the ring-back tone to the calling side. CONSTITUTION:Receiving call signal 1 sent from the calling side to call out the terminal equipment at the called side, the exchange unit connects the calling side to the circuit of the terminal equipment at the called side and then sends incoming signal 2 and ring-back tone 3 to the terminal equipment at the called side and the calling side each and simultaneously. Then the terminal equipment at the called side receives automatically signal 2 in 2-3 times, and then sends back answer signal 4. Thus the connection of the circuit can be confirmed at the calling side by the ring-back tone, and also talking possible time band 5 can be known easily by the fact that the ring-back tone is cut off by the answer signal sent from the terminal equipment at the called side. As a result, the talking possible situation of the terminal equipment at the called side can be confirmed at the calling side without adding any external unit.
