FOREWORD
1) ISO (International Organization for Standardization) and IEC (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. Their preparation is entrusted to technical
committees; any ISO and IEC National Committee interested in the subject dealt with may participate in this
preparatory work. International governmental and non-governmental organizations liaising with ISO and IEC
also participate in this preparation.
2) In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to
national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the
national bodies casting a vote.
3) The formal decisions or agreements of IEC or ISO on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested IEC and ISO National Committees.
4) IEC, ISO or ISO/IEC Publications have the form of recommendations for international use and are accepted by
IEC and ISO National Committees in that sense. While all reasonable efforts are made to ensure that the
technical content of IEC, ISO or ISO/IEC Publications is accurate, IEC or ISO cannot be held responsible for
the way in which they are used or for any misinterpretation by any end user.
5) In order to promote international uniformity, IEC and ISO National Committees undertake to apply IEC, ISO or
ISO/IEC Publications transparently to the maximum extent possible in their national and regional publications.
Any divergence between any ISO/IEC Publication and the corresponding national or regional publication should
be clearly indicated in the latter.
6) ISO or IEC provide no marking procedure to indicate their approval and cannot be rendered responsible for any
equipment declared to be in conformity with an ISO/IEC Publication.
7) All users should ensure that they have the latest edition of this publication.
8) No liability shall attach to IEC or ISO or its directors, employees, servants or agents including individual
experts and members of their technical committees and IEC or ISO member bodies for any personal injury,
property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including
legal fees) and expenses arising out of the publication of, use of, or reliance upon, this ISO/IEC publication or
any other IEC, ISO or ISO/IEC publications.
9) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
10) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
International Standard ISO/IEC 14543-3-3 was prepared by subcommittee 25: Interconnection
of information technology equipment, of ISO/IEC joint technical committee 1: Information
technology.
This International Standard is a product family standard. It is not intended to be used as a
stand-alone standard.
This International Standard has been approved by vote of the member bodies, and the voting
results may be obtained from the address given on the title page.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

INTRODUCTION
The application interface layer is the layer between the application layer and the application. It
contains the communication relevant tasks of the application. It eases the communication task
of the application by offering a communication interface that abstracts from many application
layer details.
This International Standard allows single-processor and dual-processor device designs. A dual
processor device uses additional services to communicate via a serial External Message
Interface with the external user application running in the second processor.
The following clauses specify the client and server functioning and the communication interface
of the internal user application located in the Bus Access Unit (BAU).
The application interface layer contains the following objects and the access routines to them.
– Group objects: these can be accessed via Transport layer Service Access Points
(TSAPs) on multicast communication services; see the corresponding clause in
ISO/IEC 14543-3-2. Group objects may also be references to interface objects.
– Interface objects: these can be accessed via application services on point-to-point
connectionless and point-to-point connection-oriented communication modes. The
interface objects are divided into system interface objects and application interface
objects.
• System interface objects are
− the device object,
− the group address table object,
− the association table object, and
− the application object.
• System interface objects are relevant for network management as specified in
ISO/IEC 14543-3-4.
• Application interface objects are objects defined in the user application. They may be
defined by the internal or external user application, based on interface object structure
rules defined in this document. Application interface objects may also be referenced by
a group object reference.
The following clauses specify the data structures of each of the application interface layer
objects. Additionally, they define by which application services these objects are accessible.
Both the object client and object server functioning may be implemented by the external or the
internal application interface layer. It is recommended to locate the group
