Supply initiation voltage is the value of DC supply voltage required to start the tone ringer oscillating.  
Sustaining voltage is the value of DC supply voltage required to maintain the oscillation.  
Oscillator frequency is determined by the following equations:  
fL = 1/(1.359XR1XC1)(Hz)  
fhi = 1/(1.518XR2XC2)(Hz)  
fh2 = 1.214XfHI (Hz)  
#4.  
#5.  
#6.  
VTR and ITR the conditions applied to trigger input to start oscillation for VSUS ≤ VCC≤ V SI  
.
Trigger current must be limited to this value externally.  
VDIS and IDIS are the conditions applied to trigger input to inhibit oscillation for VSI≤ V CC  
.
