Foreword
IS0 (the International Organization for Standardization) and IEC (the Inter-
national Electrotechnical Commission) form the specialized system for worldwide
standardization. National bodies that are members of IS0 or IEC participate in the
development of International Standards through technical committees established
by the respective organization to deal with partioular fields of technical activity.
IS0 and IEC technical committees collaborate in fields of mutual interest. Other
international organizations, governmental and non-governmental, in liaison with
IS0 and IEC, also take part in the work.
In the field of information technology, IS0 and IEC have established a joint
technical committee, ISO/IEC JTC 1. Draft Internbtional 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.
International Standard ISO/IEC 8823-2 was prepared by Joint Technical
Committee ISOLEC JTC 1, Information technology, Subcommittee SC 21, Open
systems interconnection, data management and open distributed processing, in
collaboration with ITU-T. The identical text is published as ITU-T
Recommendation X.246.
ISOLEC 8823 consists of the following parts, under the general title Information
technology - Open Systems Interconnection - Connection-oriented presentation
protocol:
- Part I: Protocol specification
- Part 2: Protocol Implementation Conformqnce Statement (PICS) proforma
Annex A forms an integral part of this part of ISODEC 8823. Annex B is for

Introduction
This Recommendation I International Standard is one of a set of Recommendations I International Standards produced to
facilitate the interconnection of information processing systems. It is related to other Recommendations and International
Standards in the set as defined by the Reference Model for Open Systems Interconnection (ITU-T Rec. X.200 I
ISOhEC 7498-1). The Reference Model subdivides the area of standardization for interconnection into a series of layers
of specification, each of manageable size.
The goal of Open Systems Interconnection is to allow, with a minimum of technical agreement outside the
interconnection standards, the interconnection of information processing systems:
- from different manufacturers;
- under different managements;
-
of different levels of complexity; and
- of different technologies.
ITU-T Rec. X.226 I ISO/IEC 8823- 1 specifies the connection-oriented presentation protocol. It specifies a common
encoding and a number of functional units of presentation protocol procedures to be used to meet the needs of
presentation-service-users.
To evaluate the conformance of a particular implementation, it is necessary to have a description of the capabilities and
options which have been implemented. Such a description is called a Protocol Implementation Conformance Statement
(PICS).
This Recommendation I International Standard includes the PICS proforma for the connection-oriented presentation
protocol as defined in ITU-T X.226 I ISOhEC 8823-1.

A.2 Instructions
Purpose and structure of the proforma
A.2.1
ISO/IEC 8823-1
The purpose of this PICS proforma is to provide suppliers of implementations of ITU-T Rec, X.226
with a consistent means of stating which capabilities have been implemented.
The proforma is in the form of a questionnaire and consists of a set of items. An item is provided for each capability for
which an implementation choice is allowed. Items are also provided for major mandatory capabilities for which no
implementation choice is allowed. Each item includes an item number, an item description, a $tatus value specifying the
support requirement, and room for a support answer to be provided by the supplier.
This subclause provides general information and instructions for completion of the proforma.
Subclause A.3 is for identification of the implementation.
Subclause A.4 contains the means of specifying, at a high level, the protocol and corrigenda that have been
implemented.
Subclause AS contains the global statement of conformance.
Subclause A.6 onwards contain tables in which the supplier specifies details of the implementation options chosen.
A.2.2 Symbols, terms and abbreviations
A.2.2.1 Introduction
Notations have been introduced in order to reduce the size of tables in the PICS proforma. These have allowed the use of
multi-column layout where the columns are headed ‘Status’, and ‘Support’. The definition of each is given below.
Additionally, the following definitions apply:
(PICS) item: A row in a PICS proforma table.
(PICS) question: The question to be answered in the intersection of a PICS item and either a support column (i.e. “Is
this item supported in the context applying to this table and column”) or supported values column (i.e. “What values are
supported for this item in the context applying to this table and column”) in a PICS proforma t8bie.
Copyright release for PICS proformas
Users of this Recommendation I International Standard may freely reproduce the PICS proforma id this annex so that it can be
used for its intended purpose and may further publish the completed PICS.
ITU-T Rec. X.246 (1994 E) 3

---------------------- Page: 7 ----------------------
ISO/IEC 8823-2 : 1995 (E)
status (value): An allowed entry in the status column for an item in a PICS proforma table.
(support) answer: An allowed entry in the support or supported values columns for an item in a PICS, in answer to a
PICS question.
A.2.2.2 Prerequisite notation
If a predicate applies to a whole ICs proforma table, a prerequisite line may be specified in front of the table to which it
applies. A prerequisite line takes the form:
Prerequisite:
The meaning of such a line is that if is True then the table applies, else it is not-applicable.
A.2.2.3 Item numbering
Each line within the PICS proforma which requires implementation detail to be entered is given an item number in the
first column. The item number column provides a means of uniquely referencing each possible answer within the PICS
proforma. Such referencing is necessary for specifying predicates, conditional expressions, test suite parameters, and test
suite selection expressions.
The means of referencing individual answers is to specify the following sequence:
if, and only if, the reference is being made from another Specification, then start with an unambiguous
a)
identifier for the relevant ICs proforma specification, enclosed in parentheses - this identifier is stated in
the PICS proforma specification and is updated whenever the PICS proforma is updated - it is
O
recommended that this identifier be the relevant Specification number and year of publication, as is used
in a Normative References clause, and this is the default for such identifiers;
the number of the relevant table or, if the tables are not numbered, of the smallest subclause enclosing the
b)
relevant table;
c) a solidus character, ‘Y’;
the item number or mnemonic reference to the item, to identify the row in which the answer appears;
d)
if, and only if, more than one question occurs in the row identified by the item number or mnemonic
e)
reference, then each possible answer is implicitly labelled a, b, c, etc., from left to right, and this letter is
(“I”) if a mnemonic reference is used.
appended to the sequence, prefixed by a solidus character
If mnemonic references are specified and each uniquely identify an item in the PICS proforma, then entries b) and c) in
the above sequence may be omitted.
A.2.2.4 Status column
‘Status’ as defined in ITU-T Rec. X.226 I ISOAEC 8823-1. This column indicates the level of support required for
conformance to ITU-T Rec. X.226 I ISOAEC 8823-1. The values are as follows:
‘m’ Mandatory support is required.
O
Optional support is permitted for conformance to ITU-T Rec. X.226 I ISO/IEC 8823-1. If
‘O’
implemented, it must conform to the specifications and restrictions contained in ITU-T Rec. X.226 I
ISOAEC 8823-1. These restrictions may affect the optionality of other items.
‘0.n’ The item is optional, but the optionality is qualified (where n is the number which identifies the
qualification which is applicable). The definitions for the qualified optional statements used are written
under the tables in which first appear, and are indexed in Annex B.
The item is conditional (where II is the number which identifies the condition which is applicable). The
‘cn’
definitions for the conditional statements used are written under the tables in which they first appear,
and are indexed in Annex B.
‘da’ The item is not applicable.
A.2.2.5 Support column
The ‘Support’ column shall be completed by the supplier or implementor to indicate the level of implementation of each
feature. The proforma has been designed such that the only entries required in the ‘Support’ column are:
Yes, the feature has been implemented.
‘Y’
‘N’ No, the feature has not been implemented.
‘9
-
No answer required - it is unnecessary to answer the question with a Yes or a No because the question
has a status value of not-applicable.

Avant-propos
CIS0 (Organisation internationale de normalisation) et la CE1 (Commission
électrotechnique internationale) forment ensemble un système consacré à la nor-
malisation internationale considérée comme un tout. Les organismes nationaux
membres de 1’ISO ou de la CE1 participent au développement de Normes inter-
nationales par l’intermédiaire des comités techniques créés par l’organisation
concernée afin de s’occuper des différents domaines particuliers de l’activité tech-
nique. Les comités techniques de 1’ISO et de la CE1 collaborent dans des
domaines d’intérêt commun. D’autres organisations internationales, gouverne-
0
mentales ou non gouvernementales, en liaison avec I’ISO et la CE1 participent
également aux travaux.
Dans le domaine des technologies de l’information, I’ISO et la CE1 ont créé un
comité technique mixte, I’ISOKEI JTC 1. Les projets de Normes internationales
adoptés par le comité technique mixte sont soumis aux organismes nationaux pour
approbation, avant leur acceptation comme Normes internationales. Les Normes
internationales sont approuvées conformément aux procédures qui requièrent
l’approbation de 75 % au moins des organismes nationaux votants.
La Norme internationale ISOKEI 8823-2 a été élaboqée par le comité technique

Introduction
La présente Recommandation I Norme internationale fait partie d'une série de Recommandations I Normes
internationales consacrée à l'interconnexion des systèmes informatiques; elle est en relation avec d'autres
Recommandations et Normes internationales de cette série conformément à la définition du modèle de référence pour
l'interconnexion de systèmes ouverts, dit modèle OS1 (Rec. UIT-T X.200 I ISOKEI 7498-1). Ce modèle de référence
subdivise le champ d'application de cette interconnexion en une série de couches de spécifications ayant chacune des
dimensions maniables.
L'objectif de l'interconilexion de systèmes ouverts OS1 est de permettre, avec un minimum d'accords techniques
extérieurs aux normes, l'interconnexion de systèmes informatiques:
0
- issus de constructeurs différents;
- gérés par des systèmes différents;
- présentant différents niveaux de complexité;
- mettant en œuvre des techniques différentes.
La Rec. UIT-T X.226 I ISOKEI 8823-1 spécifie le protocole de présentation en mode orienté connexion, lequel spécifie
un codage commun et un nombre dunités fonctionnelles de procédures de protocole de présentation à utiliser pour
répondre aux besoins des utilisateurs du service de présentation.
Pour évaluer la conformité d'une instance particulière, il est nécessaire de disposer d'une description des capacités et des
options qui ont été mises en œuvre pour une spécification OS1 donnée. Une telle description est appelée déclaration de
conformité dune instance de protocole (PICS).
La présente Recommandation I Norme internationale comporte le formulaire de déclaration de conformité d'une instance
de protocole (PICS) pour le protocole de présentation en mode orienté connexion défini dans la Rec. UIT-T X.226 I

A.2 Instructions
A.2.1 Purpose and structure of the proforma
The purpose of this PICS proforma is to provide suppliers of implementations of ITU-T Rec. X.226 I ISODEC 8823-1
with a consistent means of stating which capabilities have been implemented.
The proforma is in the form of a questionnaire and consists of a set of items. An item is provided for each capability for
which an implementation choice is allowed. Items are also provided for major mandatory capabilities for which no
implementation choice is allowed. Each item includes an item number, an item description, a status value specifying the
support requirement, and room for a support answer to be provided by the supplier.
This subclause provides general information and instructions for completion of the proforma.
Subclause A.3 is for identification of the implementation.
Subclause A.4 contains the means of specifying, at a high level, the protocol and corrigenda that have been
implemented.
Subclause AS contains the global statement of conformance.
0
Subclause A.6 onwards contain tables in which the supplier specifies details of the implementation options chosen.
A.2.2 Symbols, terms and abbreviations
A.2.2.1 Introduction
Notations have been introduced in order to reduce the size of tables in the PICS proforma. These have allowed the use of
multi-column layout where the columns are headed ‘Status’, and ‘Support’. The definition of each is given below.
Additionally, the following definitions apply:
(PICS) item: A row in a PICS proforma table.
(PICS) question: The question to be answered in the intersection of a PICS item and either a support column (i.e. “Is
this item supported in the context applying to this table and column”) or supported values column (i.e. “What values are
supported for this item in the context applying to this table and column”) in a PICS proformi\ table.
l) Droits de reproduction du formulaire PICS
Les utilisateurs de la présente Recommandation I Norme internationale sont autorisés à reproduire le formulaire PICS de la
présente annexe pour utiliser celui-ci conformément à son objet. Ils sont également autorisés à publier le formulaire une fois
celui-ci complété.
Rec. UIT-T X.246 (1994 F) 3

ISO/CEI 8823-2 : 1995 (F)
status (value): An allowed entry in the status column for an item in a PICS proforma table.
(support) answer: An allowed entry in the support or supported values columns for an item in a PICS, in answer to a
PICS question.
A.2.2.2 Prerequisite notation
If a predicate applies to a whole ICS proforma table, a prerequisite line may be specified in front of the table to which it
applies. A prerequisite line takes the form:
Prerequisite:
The meaning of such a line is that if is True then the table applies, else it is not-applicable.
A.2.2.3 Item numbering
Each line within the PICS proforma which requires implementation detail to be entered is given an item number in the
first column. The item number column provides a means of uniquely referencing each possible answer within the PICS
proforma. Such referencing is necessary for specifying predicates, conditional expressions, test suite parameters, and test
suite selection expressions.
The means of referencing individual answers is to specify the following sequence:
if, and only if, the reference is being made from another Specification, then start with an unambiguous
a)
identifier for the relevant ICS proforma specification, enclosed in parentheses - this identifier is stated in
the PICS proforma specification and is updated whenever the PICS proforma is updated - it is
a
recommended that this identifier be the relevant Specification number and year of publication, as is used
in a Normative References clause, and this is the default for such identifiers;
the number of the relevant table or, if the tables are not numbered, of the smallest subclause enclosing the
b)
relevant table;
c) a solidus character, ‘7‘’;
the item number or mnemonic reference to the item, to identify the row in which the answer appears;
d)
if, and only if, more than one question occurs in the row identified by the item number or mnemonic
e)
reference, then each possible answer is implicitly labelled a, b, c, etc., from left to right, and this letter is
appended to the sequence, prefixed by a solidus character (‘Y) if a mnemonic reference is used.
If mnemonic references are specified and each uniquely identify an item in the PICS proforma, then entries b) and c) in
the above sequence may be omitted.
A.2.2.4 Status column
‘Status’ as defined in ITU-T Rec. X.226 I ISOOEC 8823-1. This column indicates the level of support required for
conformance to ITU-T Rec. X.226 I ISOOEC 8823-1. The values are as follows:
‘m’ Mandatory support is required.
a
Optional support is permitted for conformance to ITU-T Rec. X.226 I ISO/IEC 8823-1. If
‘O’
implemented, it must conform to the specifications and restrictions contained in ITU-T Rec. X.226 I
ISOOEC 8823-1. These restrictions may affect the optionality of other items.
The item is optional, but the optionality is qualified (where n is the number which identifies the
‘0.n’
qualification which is applicable). The definitions for the qualified optional statements used are written
under the tables in which first appear, and are indexed in Annex B.
‘cn’ The item is conditional (where n is the number which identifies the condition which is applicable). The
definitions for the conditional statements used are written under the tables in which they first appear,
and are indexed in Annex B.
‘da’ The item is not applicable.
A.2.2.5 Support column
The ‘Support’ column shall be completed by the supplier or implementor to indicate the level of implementation of each
feature. The proforma has been designed such that the only entries required in the ‘Support’ column are:
‘Y’ Yes, the feature has been implemented.
‘N’ No, the feature has not been implemented.
‘I
-
No answer required - it is unnecessary to answer the question with a Yes or a No because the question
has a status value of not-applicable.
