5:0
RAS[5:0]
Ring Assertion Time.
These bits set the minimum ring frequency for a valid ring signal. During ring qualification,
a timer is loaded with the RAS[5:0] field upon a TIP/RING event and decrements at a
regular rate. If a second or subsequent TIP/RING event occurs after the timer has timed
out, the frequency of the ring is too low, and the ring is invalidated. The difference between
RAS[5:0 and RMX[5:0] identifies the minimum duration between TIP/RING events to
qualify 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 RAS[5:0] value for a frequency range
[f_min, f_max], the following equation should be used: RAS[5:0] = 1 / (2 x f_min).
