Title: Message 2 Things... You probably know anyway... Early 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). From my Telephony days the echo comes mostly

Good luck. I am running dedicated echo cans and they only go to 192ms. I do not think 400ms would be regarded as toll quality which is what most links strive for. Byt the time the echo cans buffer enough so they can cancel 400 you would have some extreme latency. My .02 anyway. On Dec 6,
