SIST EN 300 195-2 V1.3.4:2003 is the Slovene adoption of EN 300 195-2 V1.3.4, published by the Slovenski inštitut za standardizacijo (SIST). It covers Integrated Services Digital Network (ISDN) supplementary service interactions on the Digital Subscriber Signalling System No. one (DSS1) protocol and specifies the Protocol Implementation Conformance Statement (PICS) proforma used to state what an implementation supports.

This document is for suppliers of implementations that claim conformance to EN 300 195-1, and it supports conformance review for both user and network implementations. In practice, it tells a supplier what to declare, and it gives testers and buyers a structured way to check which supplementary service interaction capabilities are present.

What does SIST EN 300 195-2 V1.3.4:2003 specify?

SIST EN 300 195-2 V1.3.4:2003 specifies the PICS proforma for the ISDN DSS1 supplementary service interactions described in EN 300 195-1. It is a conformance-statement document, not the protocol specification itself.

The scope says the document applies to stage three of supplementary service interactions at the ISDN T reference point, or coincident S and T reference point, using DSS1. It is based on the conformance-testing approach of ISO/IEC 9646-7.

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

• Clause 1 - Scope
• Clause 2 - References
• Clause 3 - Definitions, symbols and abbreviations
• Clause 4 - Conformance
• Annex A - PICS proforma for EN 300 195-1

Annex A is split into identification, conformance, and separate user and network sections.

What are the key requirements of SIST EN 300 195-2 V1.3.4:2003?

SIST EN 300 195-2 V1.3.4:2003 requires a conforming PICS to be technically equivalent to Annex A and to keep the same numbering and order. That matters because conformance reviews and test selection depend on a stable questionnaire structure.

A conforming PICS must describe an implementation that claims conformance to EN 300 195-1, must be completed according to Annex A, and must identify both the supplier and the implementation. In practice, this means the form is not just administrative - it is part of the evidence of claimed conformance.

Annex A requires identification of the Implementation Under Test (IUT), the System Under Test (SUT), the product supplier, the client, and a PICS contact person. That gives test labs and customers the traceability they need when comparing the declaration with the actual product.

The Global statement of conformance asks whether all mandatory capabilities are implemented. A "No" answer means mandatory items that are not supported must be identified and explained, which helps reviewers see where the implementation departs from the protocol specification.

Annex A separates the questionnaire by role:

• Roles apply to all implementations.
• User applies only to user implementations, including private network implementations.
• Network applies only to network implementations.

The major-capability tables ask whether the implementation supports specific supplementary service interactions such as CLIP, CLIR, DDI, MSN, TP, CW, CCBS, CUG, UUS, SUB, 3PTY, AOC-S, AOC-D, AOC-E, COLP, COLR, MCID, CONF, FPH, ECT, CFB, CFNR, CFU, CD, HOLD, MWI, OCB, CCNR, and SCF. This matters because each yes/no answer narrows which interaction cases apply to the product.

The subsidiary-capability tables cover more specific behavior, such as ordering of checks and selected interactions between TP, UUS, CD, CFB, CFNR, CFU, AOC-E, ECT, 3PTY, and CONF. The document also asks about facility information element components received or sent, including IdentificationOfCharge, IdentifyConferee, and UUSRequest, which are the details testers use to verify protocol behavior.

What terms does SIST EN 300 195-2 V1.3.4:2003 define?

SIST EN 300 195-2 V1.3.4:2003 defines Protocol Implementation Conformance Statement (PICS) as the supplier’s statement of which capabilities are implemented for a given OSI protocol.

A PICS proforma is the questionnaire that becomes the PICS once completed for a specific implementation.

A static conformance review compares the PICS with the static conformance requirements of the relevant standards.

An Implementation Under Test (IUT) is the implementation being checked for conformance.

A System Under Test (SUT) is the system in which the IUT resides.

A System Conformance Statement (SCS) summarizes which OSI standards a system implements and what conformance is claimed.

DSS1 means Digital Subscriber Signalling System No. one, the signalling protocol used here for supplementary service interactions.

Who uses SIST EN 300 195-2 V1.3.4:2003?

SIST EN 300 195-2 V1.3.4:2003 is used by protocol suppliers, telecom equipment manufacturers, test laboratories, and buyers or operators that need a conformance statement for ISDN supplementary service interactions. It is especially relevant when a product implements user-side or network-side DSS1 supplementary services and needs to state which interactions are supported.

What changed in SIST EN 300 195-2 V1.3.4:2003 from the previous edition?

SIST EN 300 195-2 V1.3.4:2003 is an extended and updated version of ETS 300 195-2 (1996). The foreword states that it was updated to cover the additional supplementary services Message Waiting Indication (MWI), Outgoing Call Barring (OCB), Completion of Calls on No Reply (CCNR), and Selective Call Forwarding (SCF).

Which standards are used with SIST EN 300 195-2 V1.3.4:2003?

Standard	What it contributes
EN 300 195-1 (V1.4)	The protocol specification that this PICS proforma applies to
ISO/IEC 9646-1	General concepts for conformance testing and PICS
ISO/IEC 9646-7	Guidance for Implementation Conformance Statements
CCITT Recommendation I.130	Method for characterizing telecommunication services in ISDN
ITU-T Recommendation I.411	ISDN user-network reference configurations

The foreword also names the related parts of the EN 300 195 series: Part 1 protocol specification, Parts 3 and 5 test suite structure and test purposes, and Parts 4 and 6 ATS and PIXIT proformas for user and network.

What does the SIST EN 300 195-2 V1.3.4:2003 document contain?

SIST EN 300 195-2 V1.3.4:2003 contains a structured PICS questionnaire in tabular form. Annex A includes identification fields, a global conformance statement, and separate user and network tables for major capabilities, subsidiary capabilities, protocol data units, protocol data unit parameters, timers, and call states.

The tables use status and support columns so the supplier can mark mandatory, optional, or not applicable items and state whether each capability is implemented. The document also gives instructions on how to complete the form and how the PICS relates to the SCS.

For testing, the annex points readers to specific parts of EN 300 195-1 by reference so they can map each answered item to the underlying protocol behavior. That makes the document useful for conformance review, test selection, and formal supplier declarations.
