TIP/RING Voltage Adjust.
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 improves signal headroom.

Minimum Operational Loop Current.
Adjusts the minimum loop current so the DAA can operate. Increasing the minimum opera-
tional loop current improves signal headroom at a lower TIP/RING voltage.

Current Limiting Enable.
Si3061, Si3063, and Si3065 settings:
0 = Current limiting mode disabled.
1 = Current limiting mode enabled. Limits loop current to a maximum of 60 mA per the TBR21
standard.
Si3060 and Si3062 settings:
X = Current limiting mode disabled.
DC Impedance Selection.
0 = 50 Ω dc termination is selected. Use this mode for all standard applications.
1 = 800 Ω dc termination is selected.
