SIST EN 302 093-2 V1.1.1:2005 is an ETSI European Standard that defines a Protocol Implementation Conformance Statement (PICS) proforma for Broadband Integrated Services Digital Network (B-ISDN) Digital Subscriber Signalling System No. two (DSS2) point-to-point multiconnection bearer control in a separated call and bearer environment. It tells suppliers how to state which functions and options from EN 302 093-1 their implementation supports, so conformance can be described in a standard way.

What does SIST EN 302 093-2 V1.1.1:2005 specify?

SIST EN 302 093-2 V1.1.1:2005 specifies the PICS form used to describe conformance to EN 302 093-1. In practice, it is the document a supplier completes to identify an implementation, declare supported capabilities, and show whether the implementation is a user role or a network role.

The document is organized into four clauses and one normative annex:

• Clause 1 - Scope
• Clause 2 - References
• Clause 3 - Definitions and abbreviations
• Clause 4 - Conformance
• Annex A - Normative PICS proforma for EN 302 093-1

Annex A is structured into guidance, implementation identification, protocol identification, a global conformance statement, role selection, and separate tables for the user role and the network role.

What are the key requirements of SIST EN 302 093-2 V1.1.1:2005?

The main requirement is that a supplier claiming conformance to EN 302 093-1 must complete the PICS proforma in Annex A and provide enough information to identify the supplier and the implementation. That makes the conformance claim traceable and testable.

Clause 4 says the completed PICS must be technically equivalent to the annex text and must keep the same numbering, naming, and order of items. In practice, that means the form cannot be reorganized or reworded in a way that changes how the answers are read.

Annex A.4 requires a global answer to whether all mandatory capabilities are implemented. A "No" answer indicates non-conformance, so this is the first pass/fail checkpoint for procurement, testing, or approval.

Annex A.5 says the implementation shall support exactly one major role - user role or network role. This matters because the rest of the form only applies to the role actually supported.

The user and network sections use the same pattern of questions about major capabilities and SETUP message information elements. For the separated bearer control case, the implementation has to state support for the call association information element and the bearer identifier information element.

Annex A.1.2 defines the answer codes used in the tables: mandatory, optional, not applicable, prohibited, and conditional forms. The support column uses simple responses such as Yes, No, or N/A, which helps compare implementations consistently.

A practical point from Annex A.1.2 is that support for a received PDU implies the ability to parse all valid parameters of that PDU. In other words, a product cannot claim support for a message if it cannot handle one of the valid parameters carried in it.

What terms does SIST EN 302 093-2 V1.1.1:2005 define?

Implementation Conformance Statement (ICS) - a supplier statement saying which capabilities an implementation has implemented against a specification.

ICS proforma - a questionnaire-style document that becomes an ICS when the supplier completes it.

Protocol Implementation Conformance Statement (PICS) - an ICS that applies to a protocol implementation.

Implementation Under Test (IUT) - the specific implementation being examined for conformance.

System Under Test (SUT) - the system containing the IUT, including the surrounding hardware and software context.

Protocol Data Unit (PDU) - the protocol message or data unit whose support and parameters are checked in the proforma.

Who uses SIST EN 302 093-2 V1.1.1:2005?

SIST EN 302 093-2 V1.1.1:2005 is used by suppliers of B-ISDN DSS2 implementations who need to declare conformance to EN 302 093-1. It is also used by conformance test labs, assessors, and engineering teams that need a standard way to record supported roles, messages, parameters, and capabilities.

It is relevant to telecom developers working on user or network side implementations of separated call and bearer control. It also helps purchasers and quality teams review supplier statements in a consistent format.

Which standards are used with SIST EN 302 093-2 V1.1.1:2005?

• EN 302 093-1 - the protocol specification that this PICS proforma applies to.
• ISO/IEC 9646-1 - gives the general conformance testing framework and the meaning of ICS and related terms.
• ISO/IEC 9646-7 - gives the rules for PICS proformas and their completion.
• ETS 300 406 - provides testing and specification methodology for protocol conformance work.
• EN 302 091-1 - provides the point-to-point multiconnection call control protocol that the bearer control capability depends on.
• EN 300 443-1 - provides the basic B-ISDN user-network interface layer 3 call/bearer control base used as the protocol foundation.
• EN 301 068-1 - is the reference used in Annex A for connection characteristics, including ATM transfer capability and traffic parameter indication.

What does the SIST EN 302 093-2 V1.1.1:2005 document contain?

The document contains the PICS guidance and questionnaire needed to describe an implementation against EN 302 093-1. Annex A includes identification fields for the implementation, the system, the supplier, the client, and the PICS contact person.

It also contains the role-selection table, the global conformance question, and role-specific tables for major capabilities and SETUP message information elements. The tables use status, reference, and support columns so the supplier can mark each item clearly and add comments where needed.

Annex A further explains the notation for mandatory, optional, conditional, and prohibited items, plus the way support for parameters and PDUs is interpreted. The proforma has no response items for timers or call states, so the document is focused on role, capability, and information-element support rather than detailed runtime behavior.
