Deasington (Ellis Harwood Ltd., a division of John Wiley & Sons). There are quite a number of standards associated with "X.25," in the CCITT and ISO world. X.25 itself references some physical layers (e.g., X.21 and X.21 _bis_), and covers the frame and packet levels. There are ISO standards paralleling these: ISO 7776 for the frame layer and ISO 8208 for packet. ISO 8878 deals with providing the OSI Connection-Oriented Network Service over X.25. CCITT also has a number of related standards, such as X.121 for the addressing plan and X.87 hypothetical reference connections. The X.135-X.139 series deal with performance. These are from memory; there are a number more including the X.25 interface to ISDN. -- howard@cos.com OR {uunet, decuac, sun!sundc, hadron, hqda-ai}!cos!howard (703) 883-2812 [W] (703) 998-5017 [H] DISCLAIMER: Opinions expressed are not necessarily those of the Corporation for Open Systems, its members, or any standards body.
