Description

1 Scope

1.1 General

This part of ISO/IEC ISP 10611 (AMH11) covers message transfer between message transfer agents (MTAs) using the P1 Message Transfer 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 developed.

An MTA which conforms to profiles AMH11n as specified in this part of ISO/IEC ISP 10611 shall support a normal mode OSI protocol infrastructure (AMH111) as required by both ISO/IEC 10021-6 and the CCITT X.400 Recommendations, and may additionally support an X.410 mode OSI protocol infrastructure (AMH112) as required by the CCITT X.400 Recommendations.

NOTE – An MTA which only supports the minimum requirements of AMH111 will not interwork with an MTA which only supports the minimum requirements of AMH112.

1.2 Position within the Taxonomy

This part of ISO/IEC ISP 10611 is the third part 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 specifies the following profiles:

AMH111 – Message Transfer (P1) – Normal mode;
AMH112 – Message Transfer (P1) – X.410(1984) mode.

The AMH11n 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 two or more MTAs intercommunicating within a M essage Transfer System (MTS) using the P1 protocol, as shown in figure 1.

NOTE – In an ITU-T context, a domain may be treated as an MTA for the purposes of conformance to the AMH11n profiles.

The AMH11n profiles cover all aspects of the MTA Abstract Service, as defined in clause 12 of ISO/IEC 10021-4, when realized using the P1 protocol.

The OSI upper layer services and protocols to support the Message Handling Systems functions covered by the AMH11n profiles are specified in the set of standards identified in table 1.
