Defines in an abstract way the externally visible service provided by the OSI Transport Layer in terms of: (a) the primitive actions and events of the service; (b) the parameter data associated with each primitive action and event; (c) the relationship between, and the valid sequences of, these actions and events. The service defined in this Recommendation/International Standard is that which is provided by all OSI Transport Protocols (in conjunction with the Network-Service) and which may be used by any OSI Session Protocol. Does not specify individual implementations or products, nor does it constrain the implementation of entities and interfaces within a system. Conformance of equipment to this Recommendation/International Standard is achieved by conformance to the protocols specified to fulfill the Transport Service defined in this Recommendation/International Standard.
