echo cancel for satellite just used half duplex switching as a way to get around
the echo (This led to the echo suppess tone being used for faxes and modems to
allow full duplex).</SPAN></FONT></DIV>

<DIV>Just wondering, is the echo canceller in the TE411P capable of
cancelling the echo caused by the delay over satellite link (i.e. approx
400 ms delay)? </DIV>
<DIV><FONT face=Arial color=#0000ff size=2></FONT> </DIV>
<DIV>Does anyone have any success story to share? </DIV>
<DIV><FONT face=Arial color=#0000ff size=2></FONT> </DIV>
<DIV>I'm kinda stuck with a really2 annoying echo... adjusting the gain didn't
help... and what should my zapata.conf look like for effective echo
cancellation?</DIV>
<DIV><FONT face=Arial color=#0000ff size=2></FONT> </DIV>
<DIV>Thanks in advance ^_^</DIV></BLOCKQUOTE></BODY></HTML>
