PURPOSE:To transmit the MFC signal in signal form different from one oscillator, by providing the coil every frequency signal to be transmitted in response to the signal form in the outgoing sender and connecting the primary side of the coil to the oscillator. CONSTITUTION:The dial pulse from the outgoing subscriber SUB.A is received at the outgoing register OR and the selection code by multi-frequency signal is transmitted to the opposing station via the outgoing trunk OGT from the outgoing sender OS, and the O sender OS and 1 sender OS are connected to the oscillator OSC in different signal form with multiple connection. In each OS sender, the coils L0, L1 are provided every signal frequencies f0, f1, f2 to be transmitted in response to the signal form, and the primary winding of the coils L0, L1 is connected to the signal frequencies f0, f1, f2 of one oscillator OSC, and the secondary winding is connected to the outgoing trunk OGT via the contacts s0-s2 and s1-m2, to transmit the MFC signal in different signal form. |
