DTMF Tone Detection

DTMF digits 0 to 9, *, #, A, B, C, D per Telcordia LSSGR Sec 6

Dynamic range Programmable, default set at –45 dBm to –3 dBm per tone

Minimum tone duration 40 ms, can be increased with software conﬁguration

Interdigit timing Detects like digits with a 40 ms interdigit delay

Detects different digits with a 0 ms interdigit delay

Twist and frequency variation Meets Telcordia LSSGR Sec 6 and EIA 464 requirements

Acceptable twist 10 dB

Signal/noise ratio 10 dB (referenced to lowest amplitude tone)

Noise tolerance Meets Telcordia LSSGR Sec 6 and EIA 464 requirements for Gaussian, impulse, and power

line noise tolerance

Cut-through Detects down to –36 dBm per tone into 600 Ohm load impedance

Talk-off Detects less than 20 digits while monitoring Telcordia TR-TSY-000763 standard speech
