This is probably not the right forum for this question, but..... Does anyone know where to obtain the latest ANSI FDDI specifications? Are there any FTPable copies out there? ron

There are no FTPable copies of the FDDI standards available. You can buy
current X3T9.5 committee mailings through Global Engineering at:
(800) 854-7179
(714) 261-1455 (for international)
(714) 261-7892 FAX
They will take credit card orders by FAX or phone.
The recent "April mailing of the X3T9.5 Meeting", 854 pages at $80.00,
included the most recent versions of: SMT 6.2, HRC 6, MAC-2 3.1, PHY-2
3.1, PMD 9314-3 Draft (ISO version), SMF-PMD 4.2.
The nice thing is that you can get all these as one package (~650 pages of
the 854 page mailing are the FDDI standards documents, the other 200 pages
are minutes and recent work in T9.5).
If you aren't into these docs, they are:
SMT Station Management, Rev 6.2 is the latest version in review,
most folk use 5.1 in the interim.
HRC FDDI-II, the isochronous circuit enhancement for FDDI-I.
MAC-2 Media Access Control 2, the access method, this is the new
version with improvements over the original MAC,
but is supposed to be upward comaptible.
PHY-2 Physical Layer 2, the encode/clocking level, this is the new
version with improvements over the original PHY,
but is supposed to be upward comaptible.
PMD Physical Layer Medium Dependent protocol, the multi-mode fiber
version, the ISO version is the best to use but is just coming to
press now and will replace the older ANSI version soon.
SMF-PMD Single Mode Fiber Physical Layer Medium Dependent protocol
Note that the only reason you can buy this from Global is they are
committee documents. If the standard is finished totally as PMD, PHY and
MAC already are, you have to buy them from ANSI, who makes their money
this way.
In this case X3T9.5 has issued an editor's ISO version of PMD, and the 2nd versions of PHY and MAC, as they are not available from ANSI or ISO yet.
The others are not final yet, but are essentially completed and in the
approval process.
At the moment, SMT is the one most subject to change as it is in its first
technical letter ballot review phase. So these documents represent,
for the moment, what the industry is building FDDI from as a specification.
For further questions, contact me directly.

Ron, talk to Dave Katz at katz@merit.edu. He's MERIT's FDDI god...
