Adjusts the minimum loop current at which the DAA can operate. Increasing the minimum oper-
ational loop current can improve signal headroom at lower Tip-Ring voltages.
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 legacy TBR21 standard.
DC Impedance Selection.
0 = 50 dc termination slope is selected. This mode should be used for all standard
applications.
1 = 800 dc termination is selected.
On-Hook Speed.
See OHS2.
These bits adjust the voltage on the DCT pin of the line-side device, which affects the Tip-Ring
voltage on the line. Low-voltage countries should use a lower Tip-Ring voltage. Raising the Tip-
Ring voltage can improve signal headroom.
Ringer Impedance.
0 = Maximum (high) ringer impedance.
1 = Synthesize ringer impedance. C15, R14, Z2, and Z3 must not be installed when setting this
bit.
