Ringing Waveform dc Offset.
Programs the amount of dc offset that is added to the ringing waveform during ring-
ing mode. 0 to 63.3 V programmable range, 4.907 mV/LSB, 1.005 V effective resolu-
tion.
RInging Oscillator Initial Phase.
Programs the initial phase of the ringing oscillator. 0 to 1.024 s range, 31.25 µ s/LSB
for trapezoidal ringing.
AC Ring Trip Debounce Interval.
Programs the debounce interval for the ac loop current detection circuit. Refer to
"4.8. Ring Trip Detection" on page 41 for recommended values.
