CAN/CSA-ISO/IEC-8822-96 (R2000)

Scope
 
1.1
This ITU-T Recommendation / International Standard defines (in an abstract way) the externally visible service provided by the OSI Presentation Layer in terms of

 (a) the primitive actions and events at the user/service boundary;
 (b) the parameter data associated with each primitive action and event;
 (c) the relationship between, and the valid sequences of, those actions and events.
 
 
1.2
The service defined in this ITU-T Recommendation / International Standard is the connection-oriented service which is provided by the OSI connection-oriented presentation protocol and the connectionless service which is provided by the OSI connectionless presentation protocol, each in conjunction with the OSI session-service.
 
The connection-oriented presentation service defined in this ITU-T Recommendation / International Standard may be used by an OSI application protocol defined for connection-oriented transmission. The connectionless presentation service defined in this ITU-T Recommendation / International Standard may be used by an OSI application protocol defined for connectionless transmission.
 
1.3
This ITU-T Recommendation / International Standard does not specify individual implementations or products, nor does it constrain the implementation of entities and interfaces within a computer system. There is therefore, no conformance to this ITU- T Recommendation / International Standard.
