BTD
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 timeout
of approximately 5 seconds.
RNGV
D7
Receive Overload.
This bit is set when the receive input has an excessive input level (i.e., receive pin goes below
ground). Writing a 0 to this location clears this bit and the ROVI bit (Register 4, bit 6).
0 = Normal receive input level.
1 = Excessive receive input level.
Billing Tone Detected.
This bit is set if an event, such as a billing tone, causes a disruption in the line-side power
supply. Writing a zero to BTE clears this bit.
0 = No billing tone detected.
1 = Billing tone detected.
