Abstract

Recommendation X.25 is used for many types of applications. This publication shows how to use X.25 for OSI purposes by specifying a mapping of the appropriate elements of X.25 to/from the OSI Connection mode Network Service defined in Recommendation X.213. This revision of X.223 corrects several minor errors and achieves complete interworking capability with the corresponding ISO/IEC 8878 Standard.
