... Reference MSAN-180 for details of this and equations related to ringing. Line Reversal The MT91610 can deliver Line Reversal, which is required in operation such as ANI, by simply setting LR (pin 7) to +5V. The device transmission parameters will cease during the reversal. The LR (pin 7) should be set to 0V for all normal loop operations ...

... Assume the peak Ringing Current is less than 50mA, the ringing voltage (20Hz) at Tip and Ring is given as: VTR (rms) = 0.707 * {| VBAT | + VDCRI - (15.6 * VREF)} VDCRI= Positive DC voltage at DCRI pin VBAT = Negative Battery voltage VREF= Positive DC voltage at VREF pin AC voltage at the RV input pin is therefore RV (rms)~= VTR (rms MT91610 7 ...
