Start with ISO 8208. It corresponds to the 1984 version of the CCITT X.25 Recommendation for Layer 3, but is much more readable. The ISO standards are copyrighted, but perhaps your university library will have a copy. Next try the CCITT X.25 Recommendation. It is issued every four years, with 1988 being the most recent release. Most implementations in current use correspond to the 1980 or 1984 version. The Recommendation was first issued in 1976, and most complaints I have seen here seem to relate to limitations in that version. Volume One of the DDN Protocol Handbook contains information for hosts with X.25 connections to the Defense Data Network. RFC 1009 (Requirements for Internet Gateways) has some information that may be of interest. Jim McGrath
