Dial tone tolerance  
Typical figures are at 25 °C and are for design aid only: not guaranteed and not subject to production testing.  
*NOTES  
1. dBm= decibels above or below a reference power of 1 mW into a 600 ohm load.  
2. Digit sequence consists of all DTMF tones.  
3. Tone duration= 40 ms, tone pause= 40 ms.  
4. Signal condition consists of nominal DTMF frequencies.  
5. Both tones in composite signal have an equal amplitude.  
6. Tone pair is deviated by 1.5 % 2 Hz.  
7. Bandwidth limited (3 kHz ) Gaussian noise.  
8. The precise dial tone frequencies are (350 Hz and 440 Hz)  
9. For an error rate of better than 1 in 10,000.  
2 %.  
10. Referenced to lowest level frequency component in DTMF signal.  
11. Referenced to the minimum valid accept level.  
12. Guaranteed by design and characterization.
