Data Sheet
Features
Contains two echo cancellers: 112 ms acoustic
echo canceller + 16 ms line echo canceller
Works with low cost voice codec. ITU-T G.711 or
signed mag
µ/A-Law,
or linear 2’s comp
Each port may operate in different format
Advanced NLP design - full duplex speech with
no switched loss on audio paths
Fast re-convergence time: tracks changing echo
environment quickly
Adaptation algorithm converges even during
Double-Talk
Designed for exceptional performance in high
background noise environments
Provides protection against narrow-band signal
divergence
Howling prevention stops uncontrolled oscillation
in high loop gain conditions
Offset nulling of all PCM channels
Serial micro-controller interface
ST-BUS, GCI, or variable-rate SSI PCM
interfaces
User gain control provided for speaker path
(-24 dB to +48 dB in 3 dB steps)
