SIST EN 301 487-2 V1.1.1:2005 is the Slovene adoption of the ETSI standard for Broadband Integrated Services Digital Network (B-ISDN) Digital Subscriber Signalling System No. two (DSS2) user-network interface layer 3 for switched virtual path capability. It specifies the Protocol Implementation Conformance Statement (PICS) proforma used by a supplier to state how an implementation conforms to EN 301 487-1.

What does SIST EN 301 487-2 V1.1.1:2005 specify?

SIST EN 301 487-2 V1.1.1:2005 provides the PICS questionnaire for the protocol defined in EN 301 487-1, using the conformance-testing approach of ISO/IEC 9646-7. In practice, it is the document a supplier completes when claiming conformance, so that the implementation can be identified and compared in a consistent way.

The document is organized as a short front matter, then clauses on scope, references, definitions and abbreviations, and conformance. The technical content is in Annex A, which is the normative PICS proforma for EN 301 487-1.

The foreword also places this part in a larger multi-part series:

• Part 1 - Protocol specification
• Part 2 - PICS proforma specification
• Part 3 - Test Suite Structure and Test Purposes (TSS & TP) specifications 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 - Test Suite Structure and Test Purpose (TSS & TP) specification for the network
• Part 6 - Abstract Test Suite (ATS) and partial PIXIT proforma specification for the network

What are the key requirements of SIST EN 301 487-2 V1.1.1:2005?

This standard does not define protocol behavior itself. Its key requirement is that a claim of conformance to EN 301 487-1 must be backed by a completed PICS proforma that follows Annex A exactly and identifies both the supplier and the implementation.

What the supplier has to provide

Annex A requires the supplier to complete the implementation details, including the Implementation Under Test (IUT), the System Under Test (SUT), the product supplier, the client, and a PICS contact person. This matters because the completed form must identify the exact product or build that is being assessed.

How conformance is recorded

Clause 4 says the completed PICS must be technically equivalent to Annex A, keep the numbering and order of its items, describe an implementation that conforms to EN 301 487-1, and be filled in according to the guidance in clause A.1. The support entries use standard answers such as Yes, No, and N/A, with the usual PICS status markings for mandatory, optional, irrelevant, prohibited, and qualified optional items.

How roles are handled

Annex A separates the user role and the network role. Only the supported role needs to be completed, which matters because the same protocol entity can be implemented on either side of the user-network interface.

What capabilities are declared

The proforma asks about major capabilities such as call establishment, call clearing, restart, error handling, notification procedures, transit network selection, OAM traffic descriptor handling, and end-to-end transit delay handling. In practice, this tells a buyer or tester which protocol behaviors are implemented and which are not.

What messages and information elements are covered

Annex A asks about received and transmitted messages, then drills down into information elements. It covers the common message fields, then detailed items such as Called party number, Calling party number, Connection identifier, Broadband bearer capability, Broadband low layer information, Broadband high layer information, ATM traffic descriptor, QOS parameter, Restart indicator, Transit network selection, and OAM traffic descriptor.

What timing behavior is declared

Annex A includes timers such as T301, T302, T303, T308, T309, T310, T313, T316, T317, and T322. The supplier states the supported values, which helps confirm that the implementation uses the same protocol timing expectations as the reference behavior.

What terms does SIST EN 301 487-2 V1.1.1:2005 define?

• Implementation Conformance Statement (ICS) - a statement from a supplier describing which capabilities an implementation has implemented for a given specification.
• Protocol Implementation Conformance Statement (PICS) - an ICS for a protocol implementation or system claiming conformance to a protocol specification.
• PICS proforma - a questionnaire that becomes a PICS when the supplier completes it.
• Implementation Under Test (IUT) - the implementation being described in the PICS.
• System Under Test (SUT) - the system in which the IUT resides.
• Protocol Data Unit (PDU) - the protocol message unit referred to throughout the proforma.
• Operations And Maintenance (OAM) - the maintenance-related traffic and descriptor items used in the protocol.
• Switched Virtual Path (SVP) - the capability covered by EN 301 487-1 and this PICS.

Who uses SIST EN 301 487-2 V1.1.1:2005?

Suppliers of B-ISDN DSS2 implementations use this standard to document conformance in a standard format. Test labs and conformance engineers use it to compare implementations against the protocol specification in EN 301 487-1.

It is also useful to quality managers and buyers who need evidence about protocol support on the user side or the network side. In telecom product development, it helps teams record exactly which call control features, information elements, and timers are implemented.

Which standards are used with SIST EN 301 487-2 V1.1.1:2005?

• EN 301 487-1 - defines the protocol that this PICS describes.
• ISO/IEC 9646-7 - gives the PICS framework and completion guidance.
• ISO/IEC 9646-1 - provides the general conformance-testing concepts used by the document.
• ITU-T Recommendation Q.2934 - the base switched virtual path recommendation behind EN 301 487-1.
• ETSI ETS 300 443-1 and ITU-T Recommendation Q.2931 - supply related B-ISDN call and connection control references used throughout the proforma.
• Q.921, X.25, ISO/IEC 8802-2, X.75, Q.922, ISO/IEC 7776, ISO/IEC 8208, X.223, ISO/IEC 8878, X.233, ISO/IEC 8473, T.70, ISO/IEC 9577, Q.33 - support the detailed low-layer, high-layer, and transport-related information element choices in Annex A.

What does the SIST EN 301 487-2 V1.1.1:2005 document contain?

SIST EN 301 487-2 V1.1.1:2005 contains the completed-form structure for identifying the implementation, the protocol, and the supplier contact information, followed by role selection and detailed capability questions. Annex A then breaks the protocol into tables for messages, information elements, timer behavior, and the internal structure of received and transmitted information elements.

The annex is especially useful for testing and certification because it turns the protocol specification into a yes/no questionnaire. It also includes guidance on how to interpret transparent and non-transparent information elements, and how to treat user-side and network-side answers separately.
