Establishes definitions of terms and conventions for reference by Standards defining the connection-oriented or connectionless-mode (N)-services provided by the Reference Model for Open Systems Interconnection (AS 2777). In particular, it is concerned with conventions relating to a point-to-point connection, or instance of a point-to-point communication within a layer of the Reference Model. This Standard is identical with and has been reproduced from ISO/TR 8509:1987.

This Technical Report establishes definitions of terms and conventions for reference by standards defining the connection-oriented or connectionless-mode (N)-services provided by the Reference Model for Open Systems Interconnection (ISO 7498). In particular, it is concerned with conventions relating to a point-to-point connection, or instance of a point-to-point communication within a layer of the Reference Model.NOTE - The scope of this Technical Report has been restricted to meet a specific urgent need for the Network, Transport and Session Layers. Where appropriate it can be applied to other layers.Conventions for the other types of (N)-service, and wider issues of the underlying semantic model for (N)-services are the subject of further study.
