Dug, Bill c, etc… I seem to remember that more than one patent is required to put together standards based working DMT system. Weather it is DSL Lite or full rate it does not matter; more than one patent is required. Dug gets a gold star next to his name for going back and digging up the Wavelet versus DFFT signal processing algorithm discussions. (Dug beats me to the punch… again). The more seasoned investors in this technology will remember that it was with wavelets that Awre was able to get around licensing a unique PART of Amati's many ADSL related patents. On the other hand I also "believe" there were other implementation techniques that Aware would not have been able to get around, for example "echo cancellation". (I'm sure they would need it for full rate and "might" need it for Lite, depending on what kind of signal to noise the system requires". This is just one example. I also seem to remember ADI pr licensing the needed patents (by the way, this is where the licensing revenue will come from, the chip manufactures). To this day I believe only Orckit/Fijutsu are the only holdouts. I think it is possible Awre's license royalties will be split up between TI/Amati and Awre. Awre has never released information, for competitive reasons I'm sure, detailing what patents they are using for each system. I would not be surprised to find out some of Amati's patents are required for Awre's Lite and and for certain on their full rate systems. As Dug points out, this topic was heavily debated over on the Amati thread. As a side note, I remember one guy posting various search sites for the average person to do their own patent research. No way do I have the time to find where those posts are. There are thousands and thousands and thousands of Amati posts. Pat Mudge might know who the debaters were. (Maybe it was SteveG, or maybe Bozo T Clown's posts). -Eric
