Notes:
1. dBm = decibels above or below a reference power of 1 mW into a 600
load.
2. Digit sequence consists of all 16 DTMF tones.
3. Tone duration = 40 ms. Tone pause = 40 ms.
4. Nominal DTMF frequencies are used.
5. Both tones in the composite signal have an equal amplitude.
6. The tone pair is deviated by ± 1.5% ± 2 Hz.
7. Bandwidth limited (3 kHz) Gaussian noise.
8. The precise dial tone frequencies are 350 and 440 Hz (± 2%).
9. For an error rate of less than 1 in 10,000.
10. Referenced to the lowest amplitude tone in the DTMF signal.
11. Referenced to the minimum valid accept level.
