BS ISO/IEC 10732:1993

Information technology. Use of X.25 packet layer protocol to provide the OSI connection-mode network service over the telephone network. | Status: Confirmed, Current

1 Scope This CCITT Recommendation | International Standard is applicable to the environments where the X.25 packet layer protocol, as standardized in (PLP) ISO/IEC 8208, is operated over a telephone network connection to provide the OSI Connection-mode Network Service (CONS). These environments include

1. a) telephone network leased circuit connection between two DTEs;
2. b) telephone network switched connection between two DTEs;
3. c) DTE access to a PSDN via a telephone network leased circuit connection; and
4. d) DTE access to a PSDN via a telephone network switched connection.

This provision is achieved by specifying the mapping of the CONS primitives and parameters to and from the elements of the protocols used.
