Bernard, do you know of anyone using 256 QAM modulation downstream? I have seen 128 QAM being used,but not 256 QAM. The trade offs between QAM and QPSK on the upstream are well documented,does TERN using QPSK lose a significant portion of potential of upstream throughput using QPSK? Is that where they are getting a significant portion of their upstream robustness from QPSK? Hiram
