Ring Detector Full-Wave Rectifier Enable.
When RNGV (Register 24) is disabled, this bit controls the ring detector mode and the asser-
tion of the RGDT pin. When RNGV is enabled, this bit configures the RGDT pin to either follow
the ringing signal detected by the ring validation circuit, or to follow an unqualified ring detect
one-shot signal initiated by a ring-threshold crossing and terminated by a fixed counter time-
out of approximately five seconds.
