Scope

1.1

General This part of ISO/IEC ISP 12063 covers access to a Message Transfer System (MTS) in an EDI Messaging (EDIMG) environment using the P3 MTS Access Protocol (see also figure 1). These specifications form part of the EDI Messaging application functions, as defined in the parts of ISO/IEC ISP 12063, and are based on the Common Messaging content type-independent spec ifications in ISO/IEC ISP 10611.

An MTA or an MTS-user which conforms to profile AMH33 as specified in this part of ISO/IEC ISP 12063 shall support pr ofile AMH12 as specified in ISO/IEC ISP 10611-4.

An MTA or an MTS-user which conforms to profile AMH35 as specified in this part of ISO/IEC ISP 12063 shall support profile AMH14 as specified in ISO/IEC ISP 10611-4.

1.2

Position within the Taxonomy This part of ISO/IEC ISP 12063 is the fourth part of a multipart ISP identified in ISO/IEC TR 10000-2 as ""AMH3, Message Handling Systems - EDI Messaging"" (see also ISO/IEC TR 10000-1, subclause 8.2 for the definition of multipart ISPs).

This part of ISO/IEC ISP 12063 specifies the following profiles: AMH33 - EDIMG Requirements for MTS Access (P3); AMH35 - EDIMG Requirements for MTS 95 Access (P3).

The AMH33 and AMH35 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 EDI MTS-user - specifically, the intercommunication between a message transfer agent (MTA) and an EDI MTS-user using the P3 protocol, as shown in figure 1.

The AMH33 and AMH35 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 in an EDIMG environment.

The OSI upper layer services and protocols to support the Message Handling Systems functions covered by the AMH33 and AMH35 profiles are specified in subclause 1.3 of ISO/IEC ISP 10611-4.
