CAN/CSA-ISO/IEC ISP 12062-2-01

This National Standard of Canada is equivalent to International Standard ISO/IEC ISP 12062-2:1997. 1 Scope 1.1 General This part of ISO/IEC ISP 12062 covers the interchange of messages between Interpersonal Messaging (IPM) User Agents (UAs) (see also figure 1). These specifications form part of the Interpersonal Messaging application functions, as defined in the parts of ISO/IEC ISP 12062, and are based on the Common Messaging content type-independent specifications in ISO/IEC ISP 10611. 1.2 Position within the taxonomy This part of ISO/IEC ISP 12062 is the second part of a multipart ISP identified in ISO/IEC TR 10000-2 as AMH2, Message Handling Systems - Interpersonal Messaging (see also ISO/IEC TR 10000-1, 8.2 for the definition of multipart ISPs). This part of ISO/IEC ISP 12062 specifies the following profile: AMH21 - IPM Content The AMH21 profile may optionally be combined with profiles AMH23, AMH24, AMH25 or AMH26 (see annex D of ISO/IEC ISP 12062- 1) specifying OSI MHS communications protocols and supporting services for an IPM UA. 1.3 Scenario The model used is one of indirect interchange of interpersonal messages (content types 22 and 2) between IPM UAs via an intermediate Message Transfer System (MTS), as shown in figure 1. The provision of, and access to, the MTS is outside the scope of this profile. The MHS services and functions covered by the AMH21 profile are specified in ISO/IEC 10021-7. There are no OSI upper layer services and protocols within the scope of the AMH21 profile.
