3.2 Non-Intrusive Line Monitoring, Display Feature (Caller ID) Signal
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. After a valid ringing

3.2.1 Frequency Response
The blocking capacitors used in this application circuit
affect the frequency response of the system. With the
components shown, response rolls off 3dB @ 166Hz.
Other values can be used for different response
characteristics.
3.3 Regulatory Issues
Component sizing and value recommendations shown
in the application circuits above will need to be
reviewed with regard to the regulatory and safety
requirements for each particular application.
