Foreword
ISO (the International Organization for Standardization) and IEC (the
International Electrotechnical Commission) form the specialized system
for worldwide standardization. National bodies that are members of ISO
or IEC participate in the development of International Standards through
technical committees established by the respective organization to deal
with particular fields of technical activity. ISO and IEC technical
committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO
and IEC, also take part in the work.
In the field of information technology, ISO and IEC have established a
joint technical committee, ISO/IEC JTC 1. In addition to developing
International Standards, ISO/IEC JTC 1 has created a Special Group on
Functional Standardization for the elaboration of International
Standardized Profiles.
An International Standardized Profile is an internationally agreed,
harmonized document which identifies a standard or group of standards,
together with options and parameters, necessary to accomplish a function
or a set of functions.
Draft International Standardized Profiles are circulated to national bodies
for voting. Publication as an International Standardized Profile requires
approval by at least 75 % of the national bodies casting a vote.
International Standardized Profile ISO/IEC ISP 12062-4 was prepared
with the collaboration of
— OSI Asia-Oceania Workshop (AOW);
— European Workshop for Open Systems (EWOS);
— Open Systems Environment Implementors’ Workshop (OIW).
This second edition cancels and replaces the first edition (ISO/IEC ISP
12062-4:1995), which has been technically revised. It also incorporates
Technical Corrigendum 1:1996.
ISO/IEC ISP 12062 consists of the following parts, under the general title
Information technology - International Standardized Profiles AMH2n -
Message Handling Systems - Interpersonal Messaging:
— Part 1: IPM MHS Service Support
— Part 2: AMH21 - IPM Content
— Part 3: AMH22 - IPM Requirements for Message Transfer (P1)
— Part 4: AMH23 and AMH25 - IPM Requirements for MTS Access (P3)
and MTS 94 Access (P3)

Introduction
This part of ISO/IEC ISP 12062 is defined within the context of Functional
Standardization, in accordance with the principles specified by ISO/IEC
TR 10000, “Framework and Taxonomy of International Standardized
Profiles”. The context of Functional Standardization is one part of the
overall field of Information Technology (IT) standardization activities,
covering base standards, profiles, and registration mechanisms. A profile
defines a combination of base standards that collectively perform a
specific well-defined IT function. Profiles standardize the use of options
and other variations in the base standards, and provide a basis for the
development of uniform, internationally recognized system tests.
One of the most important rôles for an ISP is to serve as the basis for the
development (by organizations other than ISO and IEC) of internationally
recognized tests. ISPs are produced not simply to ‘legitimize’ a particular
choice of base standards and options, but to promote real system
interoperability. The development and widespread acceptance of tests
based on this and other ISPs is crucial to the successful realization of this
goal.
The text for this part of ISO/IEC ISP 12062 was developed in close
cooperation between the MHS Expert Groups of the three Regional
Workshops: the North American OSE Implementors’ Workshop (OIW),
the European Workshop for Open Systems (EWOS) (jointly with the
corresponding expert group of the European Telecommunications
Standards Institute - ETSI) and the OSI Asia-Oceania Workshop (AOW).
This part of ISO/IEC ISP 12062 is harmonized between these three
Workshops and it has been ratified by the plenary assemblies of all three
Workshops.

Part 4:
AMH23 and AMH25 - IPM Requirements for MTS Access (P3)
and MTS 94 Access (P3)
1 Scope
1.1 General
This part of ISO/IEC ISP 12062 covers access to a Message Transfer System (MTS) in an Interpersonal
Messaging (IPM) environment using the P3 MTS Access Protocol (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.
An MTA or a MTS-user which conforms to profile AMH23 as specified in this part of ISO/IEC ISP 12062 shall
support profile AMH12 as specified in ISO/IEC ISP 10611-4.
An MTA or a MTS-user which conforms to profile AMH25 as specified in this part of ISO/IEC ISP 12062 shall
support profile AMH14 as specified in ISO/IEC ISP 10611-4.
1.2 Position within the taxonomy
This part of ISO/IEC ISP 12062 is the fourth part of a multipart ISP identified in ISO/IEC TR 10000-2 as “AMH2,
Message Handling Systems - Interpersonal Messaging”.
This part of ISO/IEC ISP 12062 specifies the following profiles:
AMH23 - IPM Requirements for MTS Access (P3)
AMH25 - IPM Requirements for MTS 95 Access (P3)
The AMH23 and AMH25 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 IPM MTS-user - specifically, the intercommunication between
a message transfer agent (MTA) and an IPM MTS-user using the P3 protocol, as shown in figure 1.

3 Definitions
For the purposes of this part of ISO/IEC ISP 12062, the following definitions apply.
Terms used in this part of ISO/IEC ISP 12062 are defined in the referenced base standards; in addition, the
following terms are defined.
3.1 General
3.1.1 Basic requirement: an Element of Service, protocol element, procedural element or other identifiable
feature specified in the base standards which is required to be supported by all MHS implementations.
3.1.2 Functional group: a specification of one or more related Elements of Service, protocol elements,
procedural elements or other identifiable features specified in the base standards which together support a
significant optional area of MHS functionality.
NOTE - A functional group can cover any combination of MHS features specified in the base standards for which the effect
of implementation can be determined at a standardized external interface - i.e. via a standard OSI communications protocol
(other forms of exposed interface, such as a standardized programmatic interface, are outside the scope of this version of
ISO/IEC ISP 12062).
3.2 Support classification
To specify the support level of operations, arguments, results and other protocol features for this part of ISO/IEC
ISP 12062, the following terminology is defined.
The following classifications are used in this part of ISO/IEC ISP 12062 to specify static conformance
requirements - i.e. capability.
NOTE - The following classifications apply only to MTS-users, as the requirements for support of operations, arguments,
results and other protocol features by an MTA are as specified in ISO/IEC 10611-4.
In the case of arguments and results (protocol elements), the classification is relative to that of the containing
element, if any. Where the constituent elements of a non-primitive element are not individually specified, then
each shall be considered to have the classification of that element. Where the range of values to be supported
for an element is not specified, then all values defined in the MHS base standards shall be supported.
3.2.1 mandatory support (m): the element or feature shall be supported. An implementation shall be able to
generate the element, and/or receive the element and perform all associated procedures (i.e. implying the ability
to handle both the syntax and the semantics of the element) as relevant, as specified in the MHS base
standards. Where support for origination (generation) and reception are not distinguished, then both capabilities
shall be assumed.

5 Conformance
This part of ISO/IEC ISP 12062 states requirements upon implementations to achieve interworking. A claim of
conformance to this part of ISO/IEC ISP 12062 is a claim that all requirements in the relevant base standards
are satisfied, and that all requirements in the following clauses and in annexes A and B of this part of ISO/IEC
ISP 12062 are satisfied.
5.1 Conformance statement
For each implementation claiming conformance to profiles AMH23 and/or AMH25 as specified in this part of
ISO/IEC ISP 12062, a PICS shall be made available stating support or non-support of each option identified in
this part of ISO/IEC ISP 12062.
The scope of conformance to profiles AMH23 and AMH25 covers both MTAs and MTS-users. A claim of
conformance to profiles AMH23 and/or AMH25 shall state whether the implementation claims conformance as
an MTA, as a UA, or as an MS which is not co-located with an MTA. The claim shall also state if the
implementation conform to profiles AMH23 and/or AMH25.
A claim of conformance to profile AMH23 shall confirm that the implementation supports profile AMH12 as
specified in ISO/IEC ISP 10611-4. A claim of conformance to profile AMH25 shall confirm that the
implementation supports profile AMH14 as specified in ISO/IEC ISP 10611-4.
A claim of conformance to profiles AMH23 and/or AMH25 as a UA shall confirm that the implementation
supports profile AMH21 as specified in ISO/IEC ISP 12062-2.
5.2 MHS conformance
This part of ISO/IEC ISP 12062 specifies implementation options or selections such that conformant
implementations will satisfy the conformance requirements of ISO/IEC 10021 and the ITU-T X.400
Recommendations.
Implementations conforming to profiles AMH23 and AMH25 shall conform to the basic requirements of profiles
AMH12 and AMH14, as appropriate to the type of implementation (i.e. MTA or MTS-user) for which conformance
is claimed.
