Set this bit to 0.
Ringer Threshold Select.
Used to satisfy country requirements on ring detection. Signals below the lower level does not
generate a ring detection; signals above the upper level are guaranteed to generate a ring
detection.
0 = 11 to 22 V
1 = 17 to 33 V
Do not modify.
Billing Tone Protect Enable.
0 = Disabled.
1 = Enabled.
When set, the DAA responds automatically to a collapse of the line-derived power supply during a
billing tone event. When off-hook, if BTE = 1 and BTD goes high, the dc termination is released
(800? presented to the line).
If BTE and RIM (U70, bit 9) are set, an RI (U70, bit1) interrupt also occurs when BTD goes high.
Receive Overload.
The bit is set when the receive input has an excessive input level. This bit is cleared by writing a 0
to this location.
0 = Normal receive input level.
1 = Excessive receive input level.
Billing Tone Detected.
This bit is set if a billing tone is detected. This bit is cleared by writing a 0 to this location.
0 = No billing tone.
1 = Billing tone detected.
