... 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 ...

... CPC5710N 3.2 Non-Intrusive Line Monitoring, Display Feature (Caller ID) Signal Reception, and Ringing Detection Application This application uses the logic input LIN/CMP to select between ringing detection or buffering display feature (caller-ID) and voice signals. Note the AC coupling of the tip and ring signals. With this circuit, setting LIN/CMP to a logic high enables the ringing detector ...
