This circuit can generate dual tone or pulse signal but should be work with the application circuit in Fig.22. If you
want to check some unwanted phone then you can turn off telephone's ring and generate some sound from buzzer
when it isn't unwanted.

This circuit can generate dual tone or pulse signal but should be work with the application circuit in Fig.22. If you
want to check unwanted phone then you can turn off telephone's ring and generate some sound from buzzer when
it isn't unwanted. And you can detect hook on or off by/HKS signal (hook off LOW). The key pad can provide
more functions than a adjunct box.
