Overview: D2's Tone Generation voice processing algorithm module generates call progress tones, DTMF digits, and MF R1 and R2 digits. The call progress algorithm generates dial, busy, reorder, and ringback tones. The DTMF algorithm generates all 16 DTMF digits. The MF algorithm generates multifrequency R1 and R2 digits. The output power of high and low frequencies can be set within a range through system configurable parameters, and the make time and break time can be specified in 8 msec units.
Ideal Performance: Integrated with other VP Open modules and tested for concurrent real-time processing on multiple voice ports.
Algorithm Verification: D2's Tone Generation tests, which test tone frequency, duration, and power, VP Open interface validation.
Availability: C5x, C54x - Available, C2xx, C6x - Consult D2
Operating System Used: VP Open specifications
Tools Supported By: TI, White Mountain, DSP Research, Go DSP, National Instruments.
