Abstract
PURPOSE:To improve measurement efficiency and also to save labor by making it possible for only the measurement staffs of a subordinate station to measure the state of a circuit by transmitting a control signal from a terminal station to a master station and by automatically sending from the master station an unmodulated wave, standard modulated wave, etc. CONSTITUTION:Once a measurer stationed at radio station B of a terminal whose circuit state is to be measured dials a preset number by telephone set 15, the dial number is received by signal converting circuit 13 by way of radio unit 14, a radio circuit and radio unit 11 of radio station A (master station) and circuit 13 judges whether the number shows the transmission of the unmodulated wave or standard modulated wave and supplies its output to radio equipment controller 12. Consequently, controller 12 actuates radio equipment 11 to send the unmodulated wave, standard modulated wave, etc., to radio station B until a release signal is received from radio station B. Thus, the state of the circuit is measured at radio station B without stationing the staffs at radio station A, so that data needed for the circuit can be obtained.
