CAN/CSA-ISO/IEC-10611-2-95

The international community has decided to make this standard available only in the English language version. It has been adopted as a National Standard of Canada on this basis. This National Standard of Canada is equivalent to International Standard ISO/IEC ISP 10611-2:1994. 1. Scope 1.1 General This part of ISO/IEC ISP 10611 specifies how the Remote Operations Service Element, the Reliable Transfer Service Element, the Association Control Service Element, the Presentation Layer, and the Session Layer standards shall be used to provide the required OSI upper layer functions for MHS (see also figure 1). These specifications are therefore the common basis for the Common Messaging application functions, as defined in the other parts of ISO/IEC ISP 10611, and for content type-dependent International Standardized Profiles for MHS that will be developed. 1.2 Position within the taxonomy This part of ISO/IEC ISP 10611 is the second part, as common text, of a multipart ISP identified in ISO/IEC TR 10000-2 as "AMH1, Message Handling Systems - Common Messaging" (see also ISO/IEC TR 10000-1, 8.2 for the definition of multipart ISPs). This part of ISO/IEC ISP 10611 does not, on its own, specify any profiles. 1.3 Scenario The model used is one of two end systems running an end-to-end association using either or both of RTSE and ROSE. and the ACSE, Presentation and Session services and protocols (see figure 1).
