NOTES
1. dBm = decibels above or below a reference power of 1 mW into a 600
load.
2. Digit sequence consists of all DTMF tones.
3. Tone duration = 40ms, tone pause = 40ms.
4. Signal condition consists of nominal DTMF frequencies.
5. Both tones in composite signal have equal amplitudes.
6. Tone pair is deviated by
±
(1.5% + 2Hz).
7. Bandwidth limited (3kHz) Gaussian noise.
8. The precise dial tone frequencies are (350Hz and 440Hz)
±
2%.
9. For an error rate of better than 1 in 10,000.
10. Referenced to lowest frequency component in DTMF signal.
11. Referenced to the minimum valid input level.
12. Refer to Fig.11. Input DTMF Tone Level at - 25dBm (- 28dBm at GS pin). Interference Frequency Range is 480 to 3400Hz.
