SIST ETS 300 661-2:1999 is the ETSI PICS proforma specification for the Broadband Integrated Services Digital Network (B-ISDN) Digital Subscriber Signalling System No. two (DSS2) Direct Dialling In (DDI) supplementary service. It is written for suppliers and testers who need to state, in a standard form, which capabilities of a DDI implementation are supported when claiming conformance to ETS 300 661-1.

What does SIST ETS 300 661-2:1999 specify?

SIST ETS 300 661-2:1999 specifies the Protocol Implementation Conformance Statement (PICS) proforma for the B-ISDN DSS2 DDI supplementary service. In practice, it tells a supplier what to complete so a user-side or network-side implementation can be described in a way that supports conformance checking against ETS 300 661-1.

The standard is organized into a short main body and two normative annexes.

Annex	What it covers
Annex A	The PICS proforma, including implementation identification, roles, user and network capability tables, and conformance statements
Annex B	A requirements list that points back to related basic call and supplementary service interactions PICS items

What are the key requirements of SIST ETS 300 661-2:1999?

SIST ETS 300 661-2:1999 requires the supplier of an implementation claiming conformance to ETS 300 661-1 to complete the PICS proforma in annex A and provide enough information to identify both the supplier and the implementation. That matters because the resulting statement is the basis for static conformance review and for choosing which tests apply.

Completion and conformance statements

Clause 5 requires a PICS that is technically equivalent to annex A, with the same numbering and order of items. The completed PICS must describe an implementation that claims conformance to ETS 300 661-1, follow the completion instructions in clause A.1, and uniquely identify the supplier and the implementation.

Roles and applicability

Annex A splits the questionnaire into a Roles clause and separate parts for user and network implementations. The Roles clause applies to all implementations, while the User clause is completed only for user implementations, including private network implementations, and the Network clause only for network implementations. This matters because the same product may not need to answer both sides.

Identification data

Annex A asks for the date of the statement, the Implementation Under Test (IUT), the System Under Test (SUT), product supplier details, client details, and a PICS contact person. In practice, this lets testers trace the exact version and configuration being assessed and know who can answer follow-up questions.

Numbering options

For user implementations, annex A requires support for incomplete ISDN number operation from the agreed starting point within the full ISDN number, and support for full ISDN number operation. For network implementations, annex A covers delivery of the full ISDN number or delivery of a partial ISDN number from the agreed starting point, with support for at least one of the two network options required. This is important because numbering behavior affects call setup compatibility and how numbers are presented across the interface.

Relations to basic call and supplementary service interactions

Annex B adds requirements linked to the basic call PICS and to supplementary service interactions PICS. It includes items for incoming calls, overlap receiving, the Called party number information element, and DDI interactions with other implemented supplementary services. In practice, this means DDI conformance is checked together with related call control and supplementary service behavior, not in isolation.

What terms does SIST ETS 300 661-2:1999 define?

• Protocol Implementation Conformance Statement (PICS) - A statement from the supplier that identifies which capabilities of a protocol implementation are implemented.
• PICS proforma - A questionnaire-style document that becomes a PICS when completed for a specific implementation.
• static conformance review - A review that compares the completed PICS with the static conformance requirements in the relevant standards.
• Implementation Under Test (IUT) - The implementation being assessed for conformance.
• System Under Test (SUT) - The system in which the IUT resides.
• System Conformance Statement (SCS) - A statement that summarizes which standards a system implements and claims conformance to.

Who uses SIST ETS 300 661-2:1999?

SIST ETS 300 661-2:1999 is used by protocol suppliers, network operators, private network implementers, and conformance test organizations. They use it to document supported DDI capabilities, complete conformance statements, and decide which test cases and compatibility checks apply to a given B-ISDN DSS2 implementation.

Which standards are used with SIST ETS 300 661-2:1999?

• ETS 300 661-1 - The protocol specification for the DDI supplementary service; this is the standard that the PICS refers to.
• ETS 300 443-1 - The B-ISDN DSS2 basic call/bearer control protocol specification used in the related conformance framework.
• ETS 300 443-2 - The PICS proforma specification for the basic call/bearer control part.
• ETS 300 669-2 - The PICS proforma specification for supplementary service interactions.
• ISO/IEC 9646-1 - Gives the general conformance testing concepts used for PICS and static conformance review.
• ISO/IEC 9646-7 - Gives the guidance for implementation conformance statements and their proforma form.
• ITU-T Recommendation I.130 - Provides the method for characterizing telecommunication services and network capabilities.
• ITU-T Recommendation I.413 - Defines the B-ISDN user-network interfaces used by the scope.

What does the SIST ETS 300 661-2:1999 document contain?

SIST ETS 300 661-2:1999 contains a PICS proforma laid out as tables in annex A, with identification fields, a global conformance statement, and capability tables for roles, user, and network behavior. The user tables cover major capabilities such as numbering options, while the network tables cover the corresponding delivery options.

Annex B contains requirements lists that map DDI-related items back to the basic call PICS and supplementary service interactions PICS. Those tables are used to record how DDI interacts with incoming calls, overlap receiving, the Called party number information element, and other supplementary services.

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 1 of a multi-part standard covering the Digital Subscriber Signalling System No. two
(DSS2) protocol specification for the Broadband Integrated Services Digital Network (B-ISDN) Direct
Dialling In (DDI) supplementary service, as described below:
Part 1: "Protocol specification";
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".
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 300 661 is applicable to the stage three of the Direct Dialling In (DDI)
supplementary service for the pan-European Broadband Integrated Services Digital Network (B-ISDN) as
provided by European public telecommunications operators at the T reference point or coincident S and
B B
T reference point (as defined in ITU-T Recommendation I.413 [8]) by means of the Digital Subscriber
B
Signalling System No. two (DSS2). Stage three identifies the protocol procedures and switching functions
needed to support a telecommunication service (see ITU-T Recommendation I.130 [7]).
This ETS provides the Protocol Implementation Conformance Statement (PICS) proforma for the B-ISDN
DSS2 DDI supplementary service protocol as specified in ETS 300 661-1 [3] in compliance with the
relevant requirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 [6].
The supplier of a protocol implementation which is claimed to conform to ETS 300 661-1 [3] 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
For the purposes of this ETS, the following definitions apply, in addition to those given in
ETS 300 661-1 [3]:
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 [5]).
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 [5]).
static conformance review: A review of the extent to which the static conformance requirements are met
by the IUT, accomplished by comparing the PICS with the static conformance requirements expressed in
the relevant standard(s) (see ISO/IEC 9646-1 [5]).
