Norminal rate (fHA) is the HFO when the output of LFO is high • fH2 = 1.25fH1, higher rate(fH2) is the HFO when the output of LFO is low.

C1 also provides isolation from DC voltages(48V) on the line. After full wave rectification by the bridge, the waveform is filtered by capacitor(C4) to provide a DC supply for Tone Ringer chip. As this voltage exceeds the initiation voltage VCC(INI) oscillation starts. With the components shown, the output frequency chops between fH1 and fH2 at a fL rate. The loudspeaker load is coupled through a 1300Ω to 8Ω transformer. To prevent DC power supply regulation problems due to high source impedance of the telephone line and coupling components C1 and R1, while the output impedance of the 5001P circuit is quite low, the load impedance must be kept fairly high. The output coupling capacitor (C5) is required with transformer coupled loads. The variable resistor (R6) is u.
