Square Wave Input Signal and Trapezoidal Power Ring Signal Output (continued)
The following charts are meant to give some guidance to the relationship between crest factor, battery voltage, and
R
During nonring modes, the square wave input may be left on or removed from RING
signal will be removed from tip and ring even if the low-voltage input is still present at RING
the waveform has certain advantages in terms of the timing of state. These advantages are detailed in the Switch-
ing Behavior of L9215 Ringing SLIC Application Note.
