Abstract

PURPOSE:To avoid the useless application of the circuit and thus secure an effective use of the circuit, by realizing the release of circuit at the calling subscriber side in case no answer is obtained due to the absence of the called subscriber or in the case of the misdialing, etc. CONSTITUTION:The called subscriber side C where the terminal call signal 1 is received from the calling subscriber side A sends back the ring-back tone signal 2 until an answer is obtained. Only when this signal 2 is on, the electric wave is transmitted. Thus the release signal 3 is transmitted from the side A in case no answer is obtained due to the absence of the called subscriber C or the circuit is released at the side A owing to the misdialing or the like. And the signal 3 is received at the master station unit B while the signal 2 is off, and the signal 3 is transmitted to the side C. And the transmission of the signal 2 is discontinued when the signal 3 is received at the side C in order to secure the release of the circuit. As a result, an effective use can be secured for the circuit.
