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
A/LSB, 396.4 A effective resolution.
Usable range is 0 to 61 mA.

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
A/LSB, 396.4 A effective resolution. Usable range is 0 to
16 mA.
