These bits determine the length of the off-hook counter. The default setting is 128 ms.
00 = 512 ms
01 = 128 ms
10 = 64 ms
11 = 8 ms
On-Hook Speed 2.
Filter Pole Selection.
0 = The receive path has a low –3 dBFS corner at 5 Hz.
1 = The receive path has a low –3 dBFS corner at 200 Hz.
Line Voltage Force Disable.
0 = Normal operation.
1 = The circuitry that forces the LVS register (Register 29) to all 0s at 3 V or less is disabled. The
LVS register may display unpredictable values at voltages between 0 to 2 V. All 0s are displayed
if the line voltage is 0 V.
This bit sets the on-hook transition speed. On-hook speeds specified are measured from the
time the OH bit is cleared until loop current equals zero.
