Abstract
PURPOSE:To confirm the connection of a voice line at a telephone terminal set prior to the voice response from an opposite party by sending a special tone to a magnetic type interface line not connected yet. CONSTITUTION:A special tone generating section 5 is provided, which sends a special tone to a line at non-talking state. In case of a calling by a magnetic telephone terminal set 2, a ringer signal detection section 4 detects a ringer signal and sends incoming information to a telephone terminal set 3 via a control line 6. In selecting the line of the magnetic type telephone terminal set by the telephone terminal set 3, the connection with the special tone generating section 5 is released and connected only to the line of the opposite calling party. The telephone terminal set 3 and the magnetic telephone terminal set 2 can recognize the connection of line through the interruption of the special tone. Thus, the connection of the voice line is recognized by the telephone terminal set prior to the voice response from the opposite party and quicker line utilization is attained.
