AC Termination Select 2 (Si3018 line-side device only).
Works with the ACT bit to select one of four ac terminations:

1
The global complex impedance meets minimum return loss requirements in countries that require
a complex ac termination. For improved return loss performance, the other complex impedances
can be used.
On-Hook Speed.
This bit, in combination with the OHS2 bit (Register 31) and the SQ[1:0] bits (Register 59), sets the
amount of time for the line-side device to go on-hook. The on-hook speeds specified are measured
from the time the OH bit is cleared until loop current equals zero.
AC Termination Select. (Si3018 line-side device only).
When the ACT2 bit is cleared, the ACT bit selects the following:

Ringer Threshold Select.
This bit is 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 generate a ring
detection.
