Minimum Operation 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.

TIP/RING Voltage Adjust.
These bits adjus t 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.

AC Termination
Real 600 ? termination that satisfies the impedance
requirements of FCC part 68, JATE, and other countries.
Global complex impedance. Complex impedance that satisfies
global impedance requirements EXCEPT New Zealand. May
achieve higher return loss for countries requiring complex ac
termination.
