Digital Network Echo Canceller (ITU-T G.168)
Digital Network Echo Canceller (ITU-T G.168)
GAO’s Digital Network Echo Canceller (ITU-T G.168) software module is intended for use in the 4-wire portion of a circuit and is used for reducing the echo by digitally subtracting an estimated echo from the circuit echo. GAO’s G.168 echo cancellation software has the following fundamental requirements:
- Rapid convergence;
- Low returned echo level during single talk;
- Low divergence during double talk;
- Assured double talk detection;
- Proper operation during facsimile and low speed (9.6 kbit/s) voice-band data transmissions.
Features of Digital Network Echo Canceller (ITU-T G.168)
- Implemented in assembly or C.
- User-callable functions.
- Double-talk detection.
- Configurable echo tail length options: 8, 16, 32, 64 or 128 msec.
- Compliant with the ITU-T G.168 recommendation.
