TIP/RING Voltage Adjust.
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. Rais-
ing the TIP/RING voltage can improve signal headroom.
Minimum Operational Loop Current.
Adjusts the minimum loop current at which the DAA can operate. Increasing the minimum
operational loop current can improve signal headroom at a lower TIP/RING voltage.
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 standard.
DC Impedance Selection.
0 = 50 Ω dc termination is selected. This mode should be used for all standard applications.
1 = 800 Ω dc termination is selected.
These bits must always be written to 0.
