Items are not always numbered sequentially.Item description columnThe item description contains a brief summary of the static requirement for which a support answer isrequired.Conditions for status columnThe conditions for status column contains a specification, if appropriate, of the predicate upon which acondition status is based.Status columnThe following notations, defined in ISO/IEC 9646-7 [7], are used for the status column:IIrrelevant or out-of-scope - this capability is outside the scope of the ETS towhich this PICS proforma applies and is not subject to conformance testing inthis context;MMandatory - the capability is required to be supported;N/ANot Applicable - in the given context, it is impossible to use the capability. Noanswer in the support column is required;SIST ETS 300 796-2:1998



Page 11Draft prETS 300 796-2: February 1997OOptional - the capability may be supported or not;O.iqualified optional - for mutually exclusive or selectable options from a set. "i" isan integer that identifies an unique group of related optional items and the logicof their selection, defined below the table;XeXcluded or prohibited - there is a requirement not to use this capability in agiven context.Reference columnExcept where explicitly stated, the reference column refers to the appropriate text of ETS 300 796-1 [5]describing the particular item.NOTE:A reference indicates only the location of the most essential information about an item.All additional requirements contained in ETS 300 796-1 [5] have also to be taken intoaccount when making a statement about the conformance of that particular item.Support columnThe following notation, defined in ISO/IEC 9646-7 [7], is used for the support column:[ ] YesTick "Yes" if item is supported.[ ] NoTick "No" if item is not supported.[ ] N/ATick "N/A" if item is "not applicable".Prerequisite lineA prerequisite line takes the form: Prerequisite: .A prerequisite line after a subclause heading or table title indicates that the whole clause or the wholetable is not required to be completed if the predicate is FALSE.A.1.3Instructions for completing the PICS proformaThe supplier of the implementation shall complete the PICS proforma. For each row in each PICSproforma table the supplier shall enter an explicit answer (i.e. by ticking the appropriate "Yes", "No", or"N/A" in each of the support column boxes provided). Where a support column is left blank, or where it ismarked "N/A" without any tickbox, no answer is required.If necessary, the supplier may enter additional comments at the end of each table, or separately.More detailed instructions may be found at the beginning of each subclause of the proforma.A.2Identification of the implementationIdentification of the Implementation Under Test (IUT) and the system in which it resides (the SystemUnder Test (SUT)) should be filled in to provide as much detail as possible regarding version numbersand configuration options.The product supplier and client information should both be filled in if they are different.A person who can answer queries regarding information supplied in the PICS should be named as thecontact person.SIST ETS 300 796-2:1998

If the SUT implements more than one configuration, thena layer 3 PICS shall be created for each type of interface (and for each configuration of each interface)provided by the SUT.A.4.2Structure of the tablesThe supplier shall provide answers to the questions concerning the major roles of the IUT (table A.1). Thesupplier shall then provide answers to the questions relating to the capabilities of the IUT in one of themajor roles as appropriate.A.4.3Support for received PDU parametersIn the PDU parameter tables (see subclause A.10), the PICS proforma asks questions about theinformation elements (parameters) supported in messages (PDUs) received by the IUT. This subclauseexplains, in the context of ETS 300 796-1 [5], what "to support a received PDU parameter" means.The requirement that an IUT is able to parse an information element in a received message is alreadyimplied by claiming support for the receipt of that received message. This means that "to support areceived PDU parameter" implies more.Information elements in received messages are regarded as either transparent or non-transparent.A non-transparent information element is one that causes the protocol control entity to vary its behaviourin accordance with the content of the information element. To support a non-transparent informationelement means an IUT can process the received parameter and behave according to the proceduresdescribed in ETS 300 796-1 [5].An information element is transparent if the actions taken according to its contents are not detectable inthe subsequent behaviour of the pro

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 Integrated Services Digital Network (ISDN) Digital
Subscriber Signalling System No. two (DSS2) core aspects of the generic functional protocol for the
support of supplementary services as described below:
Part 1: "Protocol specification [ITU-T Recommendation Q.2932.1, modified]";
Part 2: "Protocol Implementation Conformance Statement (PICS) proforma specification";
Part 3: "Test Suite Structure and Test Purposes (TSS&TP) specification for the user";
Part 4: "Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing
(PIXIT) proforma specification for the user";
Part 5: "TSS&TP specification for the network";
Part 6: "ATS and partial PIXIT proforma specification for the network".
NOTE: The final structure of the parts containing the test specifications is currently under
study.
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 Open Systems Interconnection (OSI)
protocol. Such a statement is called a Protocol Implementation Conformance Statement (PICS).

1 Scope
This second part of ETS 300 796 is applicable to the stage three of the generic functional protocol core
aspects for the support of supplementary services for the pan-European Broadband Integrated Services
Digital Network (B-ISDN) as provided by European public telecommunications operators at the T
B
reference point or coincident S and T reference point (as defined in ITU-T Recommendation I.413 [9])
B B
by means of the Digital Subscriber Signalling System No. two (DSS2) protocol. Stage three identifies the
protocol procedures and switching functions needed to support a telecommunication service (see CCITT
Recommendation I.130 [8]).
This ETS provides the Protocol Implementation Conformance Statement (PICS) proforma for the B-ISDN
DSS2 generic functional protocol core aspects for the support of supplementary services as specified in
ETS 300 796-1 [5] in compliance with the relevant requirements and in accordance with the relevant
guidance given in ISO/IEC 9646-7 [7].
The supplier of a protocol implementation which is claimed to conform to ETS 300 796-1 [5] 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.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of this ETS, the following definitions apply, in addition to those given in
ETS 300 796-1 [5]:
Protocol Implementation Conformance Statement (PICS): A statement made by the supplier of an
Open Systems Interconnection (OSI) implementation or system, stating which capabilities have been
implemented for a given OSI protocol (see ISO/IEC 9646-1 [6]).
PICS proforma: A document, in the form of a questionnaire, designed by the protocol specifier or
conformance test suite specifier, which when completed for an OSI implementation or system becomes
the PICS (see ISO/IEC 9646-1 [6]).

Annex A (normative): PICS proforma for ETS 300 796-1
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 Purpose 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 300 796-1 [5] may provide information in a standardized manner.
The PICS proforma is subdivided into subclauses for the following categories of information:
A.1: guidance for completing the ICS proforma;
A.2: identification of the implementation;
A.3: identification of the protocol to which this PICS proforma applies;
A.4: explanation of the PICS proforma tables;
A.5: global statement of conformance;
A.6: questions to determine roles;
A.7: questions for major capabilities;
A.8: questions for subsidiary capabilities;
A.9: questions for protocol data units;
A.10: questions for protocol data unit parameters;
A.11: questions for the facility information element structure;
A.12: questions for 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 [7].
Item column
The item column contains a unique reference (a mnemonic plus a number) for each item within the PICS
proforma. Items are not always numbered sequentially.
Item description column
The item description contains a brief summary of the static requirement for which a support answer is
required.
Conditions for status column
The conditions for status column contains a specification, if appropriate, of the predicate upon which a
condition status is based.
Status column
The following notations, defined in ISO/IEC 9646-7 [7], are used for the status column:
I Irrelevant or out-of-scope - this capability is outside the scope of the ETS to
which this PICS proforma applies and is not subject to conformance testing in
this context;
M Mandatory - the capability is required to be supported;
N/A Not Applicable - in the given context, it is impossible to use the capability. No
answer in the support column is required;

---------------------- Page: 12 ----------------------

SIST ETS 300 796-2:1998
Page 11
ETS 300 796-2: April 1998
O Optional - the capability may be supported or not;
O.i qualified optional - for mutually exclusive or selectable options from a set. "i" is
an integer that identifies an unique group of related optional items and the logic
of their selection, defined below the table;
X eXcluded or prohibited - there is a requirement not to use this capability in a
given context.
Reference column
Except where explicitly stated, the reference column refers to the appropriate text of ETS 300 796-1 [5]
describing the particular item.
NOTE: A reference indicates only the location of the most essential information about an item.
All additional requirements contained in ETS 300 796-1 [5] have also to be taken into
account when making a statement about the conformance of that particular item.
Support column
The following notation, defined in ISO/IEC 9646-7 [7], is used for the support column:
[ ] Yes Tick "Yes" if item is supported.
[ ] No Tick "No" if item is not supported.
[ ] N/A Tick "N/A" if item is "not applicable".
Prerequisite line
A prerequisite line takes the form: Prerequisite: .
A prerequisite line after a subclause heading or table title indicates that the whole clause or the whole
table is not required to be completed if the predicate is FALSE.
A.1.3 Instructions for completing the PICS proforma
The supplier of the implementation shall complete the PICS proforma. For each row in each PICS
proforma table the supplier shall enter an explicit answer (i.e. by ticking the appropriate "Yes", "No", or
"N/A" in each of the support column boxes provided). Where a support column is left blank, or where it is
marked "N/A" without any tickbox, no answer is required.
If necessary, the supplier may enter additional comments at the end of each table, or separately.
More detailed instructions may be found at the beginning of each subclause of the proforma.
A.2 Identification of the implementation
Identification of the Implementation Under Test (IUT) and the system in which it resides (the System
Under Test (SUT)) should be filled in to provide as much detail as possible regarding version numbers
and configuration options.
The product supplier and client information should both be filled in if they are different.
A person who can answer queries regarding information supplied in the PICS should be named as the
contact person.
