On-Hook Speed.
This bit, in combination with the OHS2 bit (Register 31) and the SQ[1:0] bits (Register 59), sets
the amount of time for the line-side device to go on-hook. The on-hook speeds specified are
measured from the time the OH bit is cleared until loop current equals zero.
OHS
IIR Filter Enable.
0 = FIR filter enabled for transmit and receive filters. (See Figures 7–10 on page 15.)
1 = IIR filter enabled for transmit and receive filters. (See Figures 11–16 on page 16.)
Ringer Impedance.
0 = Maximum (high) ringer impedance.
1 = Synthesized ringer impedance used to satisfy a maximum ringer impedance specification
in countries, such as Poland, South Africa, and Slovenia.
Ringer Threshold Select.
This bit, in combination with the RT2 bit, is used to satisfy country requirements on ring detec-
tion. Signals below the lower level do not generate a ring detection; signals above the upper
level are guaranteed to generate a ring detection.
