| "CDDI" or "Copper Distributed Data Interface" was originally used by
Crescendo (now owned by Cisco) to denote their proprietary FDDI over
UTP standard. There was a big debate in comp.dcom.lans.fddi over
whether or not "CDDI" was a trademark. The debate was never decided
one way or the other as I recall and today, people still refer to the
pending ANSI standard as "CDDI".
However, the more appropriate name would be "TP-PMD" for "Twisted Pair
- Physical Medium Dependent". Of course, "CDDI" has a better ring to
it, and I've found most customers, salestypes, and newspaper folks use
"CDDI" to refer to the ANSI document.
If it matters to you, replace the word "CDDI" with "ANSI TP-PMD" or
"TP-PMD". Either way, make sure that your customer knows that we're
bidding with real, ANSI-standard compliant gear, and not the
pre-standard "CDDI" stuff that is still out there. By the way, from
what I can tell, Crescendo (er, Cisco) is still trying to use "CDDI" to
reflect their new gear which does conform to the ANSI standard. Of
course, there are still adapters and hub-based products which reflect
the pre-standard and may cause some confusion for network manager
types.
If you find out that "CDDI" really is a registered trademark, please
add a note saying such.

| We must be very carefull in our use of the term 'ANSI TP-PMD
compliant'. We are prohibited from claiming comformance to a document
that is not yet ratified. TP-PMD is in draft form ONLY and will stay
as such for AT LEAST six more months.
Strictly speaking, then, all UTP equipment is pre-standard.
