These bits, in combination with the RDLY[2] bit (Register 23), set the amount of time
between when a ring signal is validated and when a valid ring signal is indicated.

RMX[5:0]
Ring Assertion Maximum Count.
These bits set the maximum ring frequency for a valid ring signal within a 10% margin of
error. During ring qualification, a timer is loaded with the RAS[5:0] field upon a TIP/RING
event and decrements at a regular rate. When a subsequent TIP/RING event occurs, the
timer value is compared to the RMX[5:0] field and if it exceeds the value in RMX[5:0] then
the frequency of the ring is too high and the ring is invalidated. The difference between
RAS[5:0] and RMX[5:0] identifies the minimum duration between TIP/RING events to qual-
ify as a ring, in binary-coded increments of 2.0 ms (nominal). A TIP/RING event typically
occurs twice per ring tone period. At 20 Hz, TIP/RING events would occur every 1/
(2 x 20 Hz) = 25 ms. To calculate the correct RMX[5:0] value for a frequency range [f_min,
f_max], the following equation should be used:
To compensate for error margin and ensure a sufficient ring detection window, it is recom-
mended that the calculated value of RMX[5:0] be incremented by 1.
