Overview

RTAF provides a real-time framework for a wide range of voice and data algorithms. Analog and/or TDM data frame processing occurs in multiples of 10 msec, and packet data processing on arbitrary / fractional times between 10 and 90 msec (sometimes referred to as "ptime").

RTAF includes options for a wide variety of voice codecs, transcoding, ptime repacketizing, echo cancellation, DTMF detection, tone generation, AGC (and other signal conditioning), PTT and other types of buffering, UDP/IP packetization, call setup, frame relay, and fax relay.

Call setup includes support for standard telephony interfaces, including on-hook and off-hook detection, ringing, and tone progress.

Frame relay includes support for synchronous serial interfaces, such as RS-422.

Fax relay is typically provided by a third-party vendor, for example ADT software supporting T.38 Group 3 fax.

On Texas Instruments DSPs and CPUs, RTAF is implemented as a DSP/BIOS or SYSBIOS priority software task, initiated by one of several user-selectable hardware interrupt types (single sample, buffer full, DMA buffer full, or other GPIO signal).
