Ringing Signal Status.
0 = Ringing oscillator output signal inactive.
1 = Ringing oscillator output signal active.
6
Reserved Read returns zero.
5
RDAC
Ringing Signal DAC/Linefeed Cross Indicator.
For ringing signal start and stop, output to TIP and RING is suspended to ensure conti-
nuity with dc linefeed voltages. RDAC indicates that ringing signal is actually present at
TIP and RING.
0 = Ringing signal not present at TIP and RING.
1 = Ringing signal present at TIP and RING.
4
RTAE
Ringing Active Timer Enable.
0 = Disable timer.
1 = Enable timer.
3
RTIE
Ringing Inactive Timer Enable.
0 = Disable timer.
1 = Enable timer.
2
ROE
Ringing Oscillator Enable.
0 = Ringing oscillator disabled.
1 = Ringing oscillator enabled.
1
RVO
Ringing Voltage Offset.
0 = No dc offset added to ringing signal.
1 = DC offset added to ringing signal.
0
TSWS
Trapezoid/Sinusoid Waveshape Select.
0 = Sinusoid
1 = Trapezoid
