Actually I think it should work just fine as it is. The difference between
DOCSIS and EuroDOCSIS is the frequency range it can support and the framming
(Annex A vs. Annex B). The EuroDOCSIS frequency range is wider. I believe the
EuroDOCSIS model can support the DOCSIS frequencies just fine. You can also
choose between Annex B (DOCSIS) and Annex A (EuroDOCSIS) with the "cable
downstream annex" command. So using your EuroDOCSIS CMTS on a DOCSIS network
should just be a matter of using only the DOCSIS frequencies and configuring
"cable downstream annex b" instead of "cable downstream annex a".
