Loop Closure Mask Interval Coefficient.
Programs the loop closure detection mask interval. Programmable range is 0 to
40.96 s, 1.25 µ s/LSB
LCR Mask During Polarity Reversal.
Programs the loop closure detection mask interval during a polarity reversal.
Programmable range is 0 to 40.96 s, 1.25 µ s/LSB
Loop Closure Detection Threshold—On-Hook to Off-Hook Transition.
Programs the loop current threshold at which a valid loop closure is detected when
transitioning from on-hook to off-hook. Hysteresis is provided by programming the
ONHKTH RAM location to a different value that detects the off-hook to on-hook tran-
sition threshold. 0 to 101.09 mA programmable range, 3.097 µ A/LSB, 396.4 µ A
effective resolution. Usable range is 0 to 61 mA.
