Richard -

DAVIC is an industry group that creates and endorses standards for
multimedia delivery over many physical media. They typically adopt
existing standards when they exist. (i.e. their spec for ADSL is the
T1E1.413 standard (DMT)). When they don't exist they tend to adapt
existing standards (for HFC they added to the European DVB standard).
Since no T1E1 standard exists for VDSL they adopted 16-CAP which I
believe stems from BBTK (Lucent) technology. I don't think that this
precludes them from adopting whatever T1E1 comes up with for VDSL, I
just think that the reference to DAVIC in the NEC release may indicate
that they have DAVIC compliant solution (16-CAP) at the present time.
Since NEC is interested in selling entire systems (not just line code
transceivers), I find it easy to believe that they may be using
Lucent chips in a VDSL type of system, and may be simultaneously
developing VDSL transceivers with Amati based on DMT. I made my
initial post because I thought people were jumping the gun in
thinking that NEC+VDSL=Amati.

By the way, DAVIC refers to VDSL as "Short-Range Baseband Asymmetrical
PHY on Copper and Coax" (doesn't quite roll off the tongue, does it?)
which is the topic of section 7.5 of part 08 of the DAVIC 1.0 spec.
