Short Circuit Current pins If you have any other question, please confirm with your sales. The supply voltage is obtained from the AC ring sig- nal and the circuit is designed so that noise on the line or variations of the ringing signal cannot affect correct operation of the device.


The two tone frequencies generated are switched by an internal oscillator in a fast sequence and made audible across an output amplifier in the loud- speaker, both tone frequencies and datasheett switching frequency can be externally adjusted.
