... Detector Considerations 2.3.1 Ringing Signal Detection 2s The CPC5710N detector is a full-wave configuration. Ringing signals will assert the output on both positive and negative parts of the ringing waveform. Hysteresis is employed by the internal comparator circuit to provide noise immunity. The set-up of the detector causes CMPOUT output pulses to remain low for most of the ringing signal positive and negative half-cycles ...
