| Overview: | D2's Low Complexity DTMF Digit Detection algorithm module detects the presence of all 16 DTMF digits that are produced by different telephones on the market under a broad range of network conditions and under international telecommunications specifications. It meets EIA 464 and Bellcore requirements for tone detection and requires minimum hardware resource. D2's Low Complexity DTMF detector is intended for "dialing" applications for customer premise equipment or telco equipment. |
| Ideal Performance: | Integrated with other VP Open modules and tested for concurrent real-time processing on multiple voice ports. |
| Algorithm Verification: | * D2's tone detection test for tone duration, tone frequency shift and twist, signal to noise, and tone levels (superset of Mitel and Bellcore tone tests) * Talk-off test with Mitel and Bellcore voice tapes * D2's set of talk-down tests (superset of Bellcore and Mitel tests) validate performance in the presence of echo, dial tone, white noise, and impulse noise * Detection of digits from a suite of telephone sets * VP Open interface validation |
