Notes
1. 0dBm=1mW power when driving a 600Ω load.
2. All 16 DTMF signal frequencies.
3. 40ms DTMF signal period and 40ms pause period.
4. Nominal DTMF frequency.
5. Low-frequency group and High-frequency group signal levels are the same.
6. DTMF signal frequency deviation is within ±1.5% ±2Hz.
7. Bandwidth limited (0 to 3kHz) Gaussian noise.
8. 350Hz and 440Hz dial tone frequencies.
9. Error rate of less than 1 in 10,000.
10. Referenced to the lowest frequency component of the DTMF signal.
11. Twist=High-frequency group tone level ÷ Low-frequency group tone level.
