Read returns zero.
On-Hook Speed
These bits set the amount of time for the line-side device to go on-hook. The on-hook
speeds specified are measured from the time the register is written until loop current
equals zero.

Current Limiting Enable.
0 = Current limiting mode disabled.
1 = Current limiting mode enabled. This mode limits loop current to a maximum of 60 mA
per the TBR21 specification.
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.
Do not modify
Ringer Threshold Select.
Used to satisfy country requirements on ring detection. Signals below the lower level do
not generate a ring detection; Signals above the upper level are guaranteed to generated a
ring detection.
0 = 13.5 to 16.5 V
1 = 19.35 to 23.65 V
