RING-TRIP COMPONENTS
where RLRT = Loop-detection threshold resistance for ring trip and CF = Crest factor of ringing signal (≈ 1.25)
RSLEW, CSLEW
Ring waveform rise time
≈ 0.214 • (R
SLEW • CSLEW) ≈ tr.
For a 1.25 crest factor @ 20 Hz, tr
≈ 10 mS.
∴ (R
SLEW = 150 kΩ, CSLEW = 0.33 µF.)
CSLEW should be changed if a different crest factor is desired.
