Ring Delay Bit 2.
This bit, in combination with the RDLY[1:0] bits (Register 22), sets the amount of time
between when a ring signal is validated and when a valid ring signal is indicated.
RDLY[2]
Ring Timeout.
These bits set when a ring signal is determined to be over after the most recent ring
threshold crossing.

Ring Confirmation Count.
These bits set the amount of time that the ring frequency must be within the tolerances set
by the RAS[5:0] bits and the RMX[5:0] bits to be classified as a valid ring signal.
