CAN/CSA-ISO/IEC ISP 10611-4-01

1Scope1.1General This part of ISO/IEC ISP 10611 covers access to a Message Transfer System (MTS) using the P3 MTS Access Protocol (see also figure 1). These specifications form part of the Common Messaging application functions, as defined in the parts of ISO/IEC ISP 10611, which form a common basis for content type- dependent International Standardized Profiles for MHS that will be de veloped.An MTA or an MTS-user which conforms to profile AMH12 as specified in this part of ISO/IEC ISP 10611 shall support an 'mts-access' application context and for the MTA also 'mts- forced-access' application context. The MTA or the MTS-user may additionally conform to profile AMH14 as specified in this part of ISO/IEC ISP 10611 shall support the 'mts-access-94' and 'mts- forced-access-94' application contexts.1.2 Position within the taxonomy This part of ISO/IEC ISP 10611 is the fourth part of a multipart ISP identified in ISO/IEC TR 10000-2 as ''AMH1, Message Handling Systems - Common Messaging''.This part of ISO/IEC ISP 10611 specifies the following profiles:AMH12 - MTS Access (P3) AMH14 - MTS 94 Access (P3)The AMH12 and AMH14 profiles may be combined with any T-Profiles (see ISO/IEC TR 10000) specifying the OSI connection-mode Transport service.1.3 Scenario The model used is one of access to an MTS by an MTS-user - specifically, the intercommunication between a message transfer agent (MTA) and an MTS-user using the P3 protocol, as shown in figure 1.The AMH12 and AMH14 profiles cover all aspects of the MTS Abstract Service, as defined in clause 8 of ISO/IEC 10021-4, when realized using the P3 protocol.
