The DTMF Generator creates standard DTMF (Dual Tone Multi-Frequency) tones that are useful for controlling phone system equipment.
To use the device, it must be graphically connected to an external analog connection that is patched into the phone system. This connection will typically require a line interface circuit, which provides electrical compliance with the telephone system and call progress functions, such as automatic on-hook and off-hook sequencing.
Tip: You can test the DTMF decoder using the DTMF Generator device.
