See Figure 6 regarding guard time adjustment.
NOTES: 1)
dBm=decibels above or below a reference power of 1 mW into a 600 ohm 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.
12)
For guard time calculation purposes.
