Ringing voltage verification. This test verifies that
the desired ringing signal has been correctly applied
to the TIP/RING pair and can be measured in the 8-
bit monitor ADC, which senses low-frequency
signals directly across T-R.
Power induction measurement. This test can
detect the presence of a power supply coupled onto
the TIP/RING pair. It can be implemented by
measuring the energy content at 50/60 Hz (normal
induction) or at 100/120 Hz (rectified power
induction). This is achieved by measuring the line
voltage using a low-pass filter in the system DSP on
the 8-bit monitor ADC while making certain there is
no ringing signal present on the line.
