Foreword
This Technical Specification (TS) has been produced by ETSI Project Telecommunications and Internet Protocol
Harmonization Over Networks (TIPHON).
Introduction
To evaluate conformance of a particular implementation, it is necessary to have a statement of which capabilities and
options have been implemented for a telecommunication specification. Such a statement is called an Implementation
Conformance Statement (ICS).
ETSI
5 ETSI TS 101 341 V1.1.1 (1999-09)
1 Scope
The present document provides the Protocol Implementation Conformance Statement (PICS) proforma for the Call
transfer supplementary service in ITU-T Recommendation H.323 [2] as specified in ITU-T
Recommendation H.450.2 [1] in compliance with the relevant requirements and in accordance with the relevant
guidance given in ISO/IEC 9646-7 [5].
The supplier of a protocol implementation which is claimed to conform to ITU-T Recommendation H.450.2 [1] is
required to complete a copy of the PICS proforma provided in annex A of the present document and is required to
provide the information necessary to identify both the supplier and the implementation.

In particular, the following terms defined in ISO/IEC 9646-1 [4] apply:
Implementation Conformance Statement (ICS): statement made by the supplier of an implementation or system
claimed to conform to a given specification, stating which capabilities have been implemented. The PICS can take
several forms: protocol PICS, profile PICS, profile specific PICS, information object PICS, etc.
ICS proforma: document, in the form of a questionnaire, which when completed for an implementation or system
becomes a PICS
Protocol ICS (PICS): ICS for an implementation or system claimed to conform to a given protocol specification

4 Conformance to this PICS proforma specification
If it claims to conform to the present document, the actual PICS proforma to be filled in by a supplier shall be
technically equivalent to the text of the PICS proforma given in annex A, and shall preserve the numbering/naming and
ordering of the proforma items.
A PICS which conforms to the present document shall be a conforming PICS proforma completed in accordance with
the guidance for completion given in clause A.1.

Annex A (normative):
PICS proforma for ITU-T Recommendation H.450.2
Notwithstanding the provisions of the copyright clause related to the text of the present document, ETSI grants that users
of the present document may freely reproduce the PICS proforma in this annex so that it can be used for its intended
purposes and may further publish the completed PICS.
A.1 Guidance for completing the PICS proforma
A.1.1 Purposes and structure
The purpose of this PICS proforma is to provide a mechanism whereby a supplier of an implementation of the
requirements defined in ITU-T Recommendation H.450.2 may provide information about the implementation in a
standardized manner.
The PICS proforma is subdivided into subclauses for the following categories of information:
- guidance for completing the PICS proforma;
- identification of the implementation;
- identification of the protocol;
- global statement of conformance;
-roles;
- major capabilities;
- subsidiary capabilities;
- operations;
- arguments, results and errors;
- timers.
A.1.2 Abbreviations and conventions
The PICS proforma contained in this annex is comprised of information in tabular form in accordance with the
guidelines presented in ISO/IEC 9646-7.
Item column
The item column contains a number which identifies the item in the table.
Item description column
The item description column describes in free text each respective item (e.g. parameters, timers, etc.). It implicitly
means "is supported by the implementation?".
ETSI
8 ETSI TS 101 341 V1.1.1 (1999-09)
Status column
The following notations, defined in ISO/IEC 9646-7, are used for the status column:
m mandatory - the capability is required to be supported;
o optional - the capability may be supported or not;
n/a not applicable - in the given context, it is impossible to use the capability;
x prohibited (excluded) - there is a requirement not to use this capability in the given context;
o.i qualified optional - for mutually exclusive or selectable options from a set. "i" is an integer which
identifies a unique group of related optional items and the logic of their selection which is defined
immediately following the table;
ci conditional - the requirement on the capability ("m", "o", "x" or "n/a") depends on the support of
other optional or conditional items. "i" is an integer identifying a unique conditional status
expression which is defined immediately following the table;
i irrelevant (out-of-scope) - capability outside the scope of the reference specification. No answer is
requested from the supplier.
Reference column
The reference column makes reference to ITU-T Recommendation H.450.2, except where explicitly stated otherwise.
Support column
The support column shall be filled in by the supplier of the implementation. The following common notations, defined in
ISO/IEC 9646-7, are used for the support column:
Y or y supported by the implementation;
N or n not supported by the implementation;
N/A, n/a or - no answer required (allowed only if the status is n/a, directly or after evaluation of a conditional
status).
If this PICS proforma is completed in order to describe a multiple-profile support in a system, it is necessary to be able
to answer that a capability is supported for one profile and not supported for another. In that case, the supplier shall
enter the unique reference to a conditional expression, preceded by "?" (e.g. ?3). This expression shall be given in the
space for comments provided at the bottom of the table. It uses predicates defined in the SCS, each of which refers to a
single profile and which takes the value TRUE if and only if that profile is to be used.
EXAMPLE 1: ?3: IF prof1 THEN Y ELSE N.
It is also possible to provide a comment to an answer in the space provided at the bottom of the table.
NOTE: As stated in ISO/IEC 9646-7, support for a received PDU requires the ability to parse all valid parameters
of that PDU. Supporting a PDU while having no ability to parse a valid parameter is non-conformant.
Support for a parameter on a PDU means that the semantics of that parameter are supported.
