NOTES:
1. All tones are generated at 0 dBm0 except for the high tones of DTMF which are at +3 dBm0.
2. The unit dBm0 represents a digital representation of an analog level; throughout this data sheet, the zero
reference point of 0 dBm0 was measured with a Hitachi HD44238P CODEC which produces a 1.231Vrms
analog signal when sent a “0 dBm0” digital code.
3. All letters and numbers contained in brackets ([ ]) represent Hexadecimal values.
4. The above hexadecimal code are sent LSB first.
