Abstract
The present invention relates to a tone signal generator. The tone signal generator includes first tone signal generation means for producing a dual-tone, multi-frequency ('DTMF') audio signal; second tone signal means for producing a plurality of non-DTMF audio signals; storage means for storing data that represents at least one channel of an output audio tone signal; and selection means for selectively loading the DTMF signal into the storage means and for selectively accumulating the non-DTMF signals into the storage means so as to generate the output tone signal.
