SIST EN 302 091-2 V1.1.3:2005 is the ETSI specification for the Protocol Implementation Conformance Statement (PICS) proforma for the Prenegotiation protocol used in B-ISDN and B-PISN with DSS2, B-QSIG, and SS7. It tells a supplier how to state, in a standard format, which protocol capabilities and options have been implemented for EN 302 091-1. It is aimed at implementation suppliers, conformance testers, and anyone who needs a comparable implementation declaration.

What does SIST EN 302 091-2 V1.1.3:2005 specify?

SIST EN 302 091-2 V1.1.3:2005 specifies the PICS proforma for the Prenegotiation protocol defined in EN 302 091-1. It applies at the QB, SB, TB and co-incident SB/TB reference points within and between B-PISNs and at the access to public B-ISDN.

The document is organized as follows:

Annex	What it covers
Annex A, normative	The PICS proforma for EN 302 091-1, with guidance, identification fields, conformance questions, and capability tables

The front matter also points to the related parts of the series: Part 1 is the protocol specification, Part 3 is the Test Suite Structure and Test Purposes (TSS&TP) specification, and Part 4 is the Abstract Test Suite (ATS) and partial PIXIT proforma specification.

What are the key requirements of SIST EN 302 091-2 V1.1.3:2005?

SIST EN 302 091-2 V1.1.3:2005 is a completion document, so its main requirement is to record implementation support in the exact PICS format of Annex A. In practice, the supplier must fill in the tables so a conformance assessor can compare one implementation with another on the same basis.

Conformance statement and form

Clause 4 states that a claimed-conforming PICS must be technically equivalent to the Annex A proforma and must keep the same numbering, naming, and order. It also says a conforming PICS is one completed according to the guidance in A.1. This matters because the completed form is only useful if it can be read and checked consistently.

Identification of the implementation

Annex A asks for details of the date of the statement, the Implementation Under Test (IUT), the System Under Test (SUT), the product supplier, the client, and a contact person. This lets testers tie the statement to a specific product, version, and configuration.

Global conformance

Annex A includes a global yes/no question on whether all mandatory capabilities are implemented. A "No" answer means non-conformance to the protocol specification, and any missing mandatory capability must be identified and explained. This is the fast check that tells a buyer or test lab whether the implementation claims full protocol conformance.

Roles and major capabilities

Annex A separates support for two roles: prenegotiation in terminal equipment and prenegotiation in a network node. It then asks about major capabilities such as invocation of prenegotiation by the originating or terminating call control entity, both during call establishment and after the first end-to-end response, as well as independent invocation after call establishment. This tells the reader whether the implementation can act in the call scenarios they need.

Protocol data units, timers, and interworking

Annex A also asks about Application Protocol Data Units (APDUs) transmitted and received, including preNegotiate and prenegotiation Alert messages and their reject cases. It lists timers T19 and T29, and it covers interworking with other networks that do not support prenegotiation for incoming and outgoing calls. In practice, this is the section that shows whether the implementation can exchange the right messages and cope with mixed-network operation.

What terms does SIST EN 302 091-2 V1.1.3:2005 define?

• Protocol Implementation Conformance Statement (PICS) - a supplier statement that records which capabilities of an OSI protocol implementation are supported.
• PICS proforma - the questionnaire-like template that becomes the PICS when it is completed.
• Implementation Under Test (IUT) - the specific implementation being described or assessed.
• System Under Test (SUT) - the system that contains the IUT.
• Major Capabilities (MC) - the main optional or conditional capabilities listed in the proforma.
• Application Protocol Data Units (APDUs) - the protocol messages whose transmission and reception support is declared.
• Timers (TM) - the timer functions whose support is recorded in the PICS.

Who uses SIST EN 302 091-2 V1.1.3:2005?

SIST EN 302 091-2 V1.1.3:2005 is used by suppliers of B-ISDN and B-PISN equipment, especially where DSS2, B-QSIG, or SS7 prenegotiation is implemented. It is also used by conformance test teams, interoperability labs, and buyers who want a structured statement of what a product supports. The document is practical for anyone who needs to compare terminal equipment and network-node behavior against the same protocol features.

Which standards are used with SIST EN 302 091-2 V1.1.3:2005?

• EN 302 091-1 - defines the Prenegotiation protocol that this PICS proforma describes.
• ISO/IEC 9646-1 - gives the general Open Systems Interconnection (OSI) conformance testing concepts and framework.
• ISO/IEC 9646-7 - gives the rules for Implementation Conformance Statements, including the PICS approach used here.
• ETSI EN 302 091 Part 3 - provides the Test Suite Structure and Test Purposes for the same protocol family.
• ETSI EN 302 091 Part 4 - provides the Abstract Test Suite and partial PIXIT proforma specification for testing.

What does the SIST EN 302 091-2 V1.1.3:2005 document contain?

Annex A contains the full PICS proforma in table form. It starts with guidance on how to complete the form, including the status symbols, support entries, and conditional expressions used in the tables. The annex then provides identification fields for the implementation and the organization completing the statement.

The rest of Annex A is a structured checklist for roles, major capabilities, APDUs transmitted and received, timers, and interworking behavior. These tables are the practical core of the document because they are what a supplier completes and what a tester or buyer reviews. The document also includes a bibliography and ETSI history information.
