4.21. Ringing Signal Generator Circuit
This section generates this ringing signal for the single line telephone. A 25Hz square wave is generated by the ASIC and sent to
low pass filter and ringing signal amplifier circuit and stepped by BELL transformer, and then passed through the ringing signal
switching relay to the single line telephone.
