It seems I botched this the last time I sent it in (to comp.dcom.telecom).
This is the group I meant to send it to.
Anyway, I am doing some work that requires knowledge of the group 2 and
group 3 facsimile protocols. Can anyone here point me to a source of this
information? Vendor manuals, standards papers, or even word of mouth or
the address of a person with a copy machine.
I need this relatively quickly so don't be shy about sending mail. I'll
probably take this information and compress it and post it to the net at
large since I believe I have seen another person or two asking for something
similar.
Thanks much,

these protocols are described in documents from CCITT (d'accord?). group 2 is simple bitmapped graphics. group 3 encodes the bitmap via a nifty combination of runlength and Huffman coding... get ready to do a lot of accurate typing if you want to do your own conversions... there are a *bunch* of PC-boards on the market which will turn your IBM PC into a fax machine... one of the companies who supplies these products might be able to get you a copy of the CCITT spec, if you don't feel like writing to France. (they must be available somewhere in the US -- i don't know where, though). a bon chance!

These are the same people who carry the ANSI standards, and the catalog I saw shows lots and lots of standards.

To get a copy of the 1984 version of the Group 2 and Group 3 recommendations, contact Omnicom, Inc, in Vienna, VA (703) 281-1135. They are the official representitives in the USA. Writing to France won't help. The CCITT is located at the ITU tower in Geneva, SWITZERLAND. To order directly from the CCITT, allow 15 weeks for delivery, and enclose a check for the correct amount in Swiss Francs. The address is: CCITT - Document Order International Telecommunications Union Place des Nation CH-1211 Geneva, Switzerland The text you are looking for the Fascicle VII.3, also known as the T-series Recommendations. Recommendation T.3 covers Group 2, T.4 covers Group 3. You should also read T.0, T.10. T.10bis, T.20, T.21, and T.30. -- AT&T o o 303-538-5004 Don Stanwyck || druco!stanwyck Denver, CO USA \__/ Telecom Standards
