Efficient decoding of Dual Tone Multi-Frequency (DTMF) signals can be achieved using the sub-band non-uniform discrete Fourier transform (SB-NDFT). In this paper, the details of its implementation on the ADSP-2
Dual-tone multi-frequency signaling (DTMF), also called touch-tone, is a system used for telecommunication signaling over an active telephone line in the voice frequency band between communication devices. Whenever a number is dialed, the DTMF is decoded by the local exchange in order to route ...
RFC 4733、セクション 3.2の説明に従って、vgwActSendDTMFアクションを使用して、Dual-Tone Multi-Frequency (DTMF) トーンを発信者に送信できます。 IBM® Voice Gateway は、RFC 4733(RTP Payload for DTMF Digits, Telephony Tones, and Telephony Signals) をサポートしています。
The telecom industry developed multi-frequency signaling (MF) as a forerunner of DTMF. It uses the same principles of DTMF but was only used by long-distance operators to signal other switchers. MF proved the reliability and ease of use of the underlying technology, so DTMF was developed for ...
The TTR simulator captures DTMF data received by a private branch exchange (PBX) switch and utilizes the instruction set of the TTR being simulated to process the received DTMF signals on the simulated TTR. Diagnostic tools allow step-by-step tracing and recording of the instructions performed by...
The method and system comprise receiving one or more dual tone multi frequency (DTMF) signals by a vehicle via an active communication channel. The one or more DTMF signals are decoded and perform a corresponding vehicle function. A system and method in accordance with the present invention ...
