Function
15:0 LCRONHK[15:0] Loop Closure Detection Threshold—Off-Hook to On-Hook Transition.
Programs the loop current threshold at which a valid loop closure event has been
terminated (the off-hook to on-hook transition). The OFFHKTH RAM location
determines the loop current threshold for detecting the off-hook to on-hook transition.
0 to 101.09 mA programmable range, 3.097 µA/LSB, 396.4 µA effective resolution.
Usable range is 0 to 61 mA.

Function
15:0 LONGDBI[15:0] Ground Key Detection Debounce Interval.
Programs the debounce interval during the ground key detection process.
Programmable range is 0 to 40.96 s, 1.25 ms/LSB.
LONGHITH: Ground Key Detection Threshold (RAM Address 27)

Name
Function
15:0 LONGHITH[15:0] Ground Key Detection Threshold.
Programs the longitudinal current threshold at which a valid ground key event is
detected. Hysteresis is provided by programming the LONGLOTH RAM location to a
different value that detects the removal of a ground key event. 0 to 101.09 mA pro-
grammable range, 3.097 µA/LSB, 396.4 µA effective resolution. Usable range is 0 to
16 mA.
