Map a character into two DTMF tones. If the character cannot be found, the frequency is -1. The low bands are: 697, 770, 852 and 941. The high bands are: 1209, 1336 and 1477 Hz. See Mitra, 3E, Digital Signal Processing, pp. 29 for more information. Band 1633 Hz is normally not used, but we can implement it anyway.
