I sent this in EMAIL, but here's a posted reply:

ISO 7498, "Information Processing Systems --- Open Systems Interconnection ---
Basic Reference Model,"  the International Organization for Standardization.

There are also additional addenda, called 7498/1, 7498/2, etc, dealing
with connectionless services, multipeer data transfer, naming and addressing,
and security (last one from memory; I wrote the original reply while
at the office).  Not all of the addenda are "standards;" there is a sequence
which goes DP, DIS, IS (Draft Protocol, Draft IS, Intl Std) and some of
them are more or less along in that sequence.  

Finally, the best place to get ISO standards is Omnicom.  (#include disclaimer)
They have high prices, but they have EVERYTHING in stock (by definition; if
they don't, they'll copy it for you and send that while you wait) and
excellent service.  As a private company, they do much better on responsiveness
and service than either ANSI (for ANSI and ISO documents, in New York),
Commerce (for CCITT documents) or TIA (for TIA/EIA standards).  They have
an 800- number.
