GAO's G.165, Line Echo Canceller (LEC) Software, cancels electrical line echoes caused by 2-to-4 wire conversion hybrids in telephone lines. The line echo canceller is also designed for integration with other software modules from GAO such as our DTMF Encoder/Decoder to enhance performance.
Line echo cancellation can be used in long distance voice communication, especially in links involving satellite networks and intercontinental long-haul circuits. It can also be employed in addition to echo suppressors for long delays. GAO's line echo canceller consists of two user-callable functions that perform echo cancellation and initialization operations.
FEATURES:
-Implemented in assembly or C.
-User-callable functions.
-Double-talk detection.
-Ideal for full-duplex operation.
-Compliant with the ITU-T G.165 recommendation.
