Ringing Waveform Present Flag.
0 = No ringing waveform present.
1 = Ringing waveform present.
Ringing Waveform Sent to Differential DAC.
0 = Ringing waveform not sent to differential DAC.
1 = Ringing waveform set to differential DAC.
Unbalanced Ringing Enable.
Enables internal unbalanced ringing generation.
0 = Unbalanced ringing not enabled.
1 = Unbalanced ringing enabled.
Ringing Active Timer Enable.
0 = Ringing active timer disabled.
1 = Ringing active timer enabled.
Ringing Inactive Timer Enable.
0 = Ringing inactive timer disabled.
