Abstract

PURPOSE:To enable the common use through the automatic exchanger between the slave station having dialing function and that not having this function. CONSTITUTION:When the call signal fa from the dialing slave station is transmitted by modulating electromagnetic waves, this is received at the master station 3, and the reception output R is given to the signal converter 11. The first call detector 13 of the converter 11 detects fa from the filter 12 and produces output, clossed the DC loop circuit of the bidirectional trunk 12, and starts the automatic exchanger 2. The call out signal fb from the slave station disabling dialing is detected with the second call out detector 16 of the signal converter 11, and the detection output starts the number setter 17. The number setter 17 gives the dial number to the dial center 15. The dial center 15 delivers the dial pulse corresponding to the dial number of the exchanger circuit and it is connected with the operator.
