Foreword
This European Telecommunication Standard (ETS) has been produced by the Signalling Protocols and
Switching (SPS) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS is part 2 of a multi-part standard covering the Service Specific Connection Oriented Protocol
(SSCOP) for the Broadband Integrated Services Digital Network (B-ISDN) as described below:
Part 1: "Protocol specification [ITU-T Recommendation Q.2110, modified]";
Part 2: "Protocol Implementation Conformance Statement (PICS) proforma specification";
Part 3: "Test Suite Structure and Test Purposes (TSS&TP) specification";
Part 4: "Abstract Test Suite (ATS) and Protocol Implementation eXtra Information for Testing (PIXIT)
specification".
Transposition dates
Date of adoption of this ETS: 3 April 1998
Date of latest announcement of this ETS (doa): 31 July 1998
Date of latest publication of new National Standard
or endorsement of this ETS (dop/e): 31 January 1999
Date of withdrawal of any conflicting National Standard (dow): 31 January 1999
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 given protocol. Such a statement is called a
Protocol Implementation Conformance Statement (PICS).

1 Scope
This second part of ETS 300 436 provides the Protocol Implementation Conformance Statement (PICS)
proforma for the Service Specific Connection Oriented Protocol (SSCOP) at the Signalling ATM
Adaptation Layer (SAAL) for the Broadband Integrated Services Digital Network (B-ISDN) as specified in
ETS 300 436-1 [1] in compliance with the relevant requirements and in accordance with the relevant
guidance given in ISO/IEC 9646-7 [3].
The supplier of a protocol implementation that is claimed to conform to ETS 300 436-1 [1] is required to
complete a copy of the PICS proforma provided in annex A of this ETS and is required to provide the
information necessary to identify both the supplier and the implementation.
2 Normative references
This ETS incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to, or revisions of any of these publications
apply to this ETS only when incorporated in it by amendment or revision. For undated references the
latest edition of the publication referred to applies.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of this ETS, the definitions in ISO/IEC 9646-1 [2] and ISO/IEC 9646-7 [3] apply. In
particular, the following terms defined in ISO/IEC 9646-1 [2] apply:
Implementation Conformance Statement (ICS): A statement made by the supplier of an implementation
or system claimed to conform to a given specification, stating which capabilities have been implemented.
The ICS can take several forms: Protocol ICS (PICS), profile ICS, profile specific ICS, and information
object ICS.
Protocol Implementation Conformance Statement (PICS): An ICS for an implementation or system
claimed to conform to a given protocol specification.
PICS proforma: A document, in the form of a questionnaire, which when completed for an
implementation or system becomes a PICS.

4 Conformance
A PICS proforma that conforms to this PICS proforma specification shall be technically equivalent to
annex A, and shall preserve the numbering and ordering of the items in annex A.
A PICS that conforms to this PICS proforma specification shall:
a) describe an implementation which conforms to ETS 300 436-1 [1];
b) be a conforming PICS proforma, which has been completed in accordance with the instructions for
completion given in clause A.1;
c) include the information necessary to uniquely identify both the supplier and the implementation.

Annex A (normative): PICS proforma for ETS 300 436-1
Notwithstanding the provisions of the copyright clause related to the text of this ETS, ETSI grants that
users of this ETS 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 ETS 300 436-1 [1] 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;
- SSCOP;
- protocol capabilities;
- protocol data units;
- system parameters.
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 [3].
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?".
Status column
The following notations, defined in ISO/IEC 9646-7 [3], 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.
O.i qualified optional - for mutually exclusive or selectable options from a set. "i" is
an integer which identifies an 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 an
unique conditional status expression which is defined immediately following the
table.
