SIST EN 300 745-2 V1.2.4:2005 is the Slovenian standard identical to EN 300 745-2 Version 1.2.4 from ETSI. It specifies the Protocol Implementation Conformance Statement (PICS) proforma for the Integrated Services Digital Network (ISDN) Message Waiting Indication (MWI) supplementary service using the Digital Subscriber Signalling System No. one (DSS1) protocol. In practice, it is the document a supplier uses to describe which MWI capabilities, procedures, messages, parameters and timers an implementation supports before conformance review.

What does SIST EN 300 745-2 V1.2.4:2005 specify?

SIST EN 300 745-2 V1.2.4:2005 specifies how to complete a PICS for the ISDN DSS1 MWI supplementary service. It is the second part of a multi-part standard for stage three of the service, and it is intended for implementations that claim conformance to EN 300 745-1.

Clause 1 sets the scope around the pan-European ISDN at the T reference point or coincident S and T reference point, and says the document follows the conformance-testing guidance in ISO/IEC 9646-7. Clause 2 names the related standards that support the PICS, clause 3 defines the key conformance-testing terms, and clause 4 states the conformance rules for a completed PICS.

Annex	What it covers
Annex A	Normative PICS proforma for EN 300 745-1
Annex B	Normative requirements list for related PICS proformas
Annex C	Informative changes with respect to the previous ETS 300 745-2

What are the key requirements of SIST EN 300 745-2 V1.2.4:2005?

SIST EN 300 745-2 V1.2.4:2005 requires a completed PICS to match annex A in content, numbering and order. A conforming PICS has to describe an implementation that claims conformance to EN 300 745-1, follow the completion instructions in Annex A, and identify both the supplier and the implementation.

How the PICS is completed

Annex A says the completed form should identify the Implementation Under Test (IUT), the System Under Test (SUT), the product supplier, the client and a contact person. That matters because conformance testing depends on knowing exactly which product, version and configuration are being assessed.

The global statement of conformance has to be answered for the implementation. If the answer is “No”, the PICS still has to be completed, with non-supported mandatory capabilities identified and explained so that reviewers can see where the implementation differs from the standard.

Which parts of the form apply

Annex A divides the PICS into a Roles clause and then separate user and network parts. The User clause is completed only for user implementations, including private network implementations, while the Network clause is completed only for network implementations.

This distinction matters because the same service behaves differently at the user side and the network side. The Roles table also distinguishes cases such as user requirements, network requirements, coincident S and T reference point support, and interworking with private ISDNs at the T reference point.

What capabilities are recorded

Annex A asks for support information in these areas:

• major capabilities
• subsidiary capabilities
• protocol data unit support
• protocol data unit parameters
• timers
• call states

That structure is useful in practice because it forces the supplier to state not only whether the service is present, but also which procedures, messages and timing behavior are implemented.

What the user part covers

For user implementations, Annex A includes message waiting indication activation, deactivation and invocation procedures. It also checks related facility information element components, including received and transmitted invoke, return result and return error items, plus user timers such as T-ACTIVATE and T-DEACTIVATE.

In practical terms, this is the part that shows whether a user terminal or user-side system can correctly request MWI services, process the service messages and handle the timing rules that go with them.

What the network part covers

For network implementations, Annex A covers the same core MWI procedures from the network side, including activation, deactivation and invocation. It also includes network-side facility information element components and the corresponding T-ACTIVATE and T-DEACTIVATE timers.

It also adds optional network capabilities such as subscription for registration of the ISDN number(s) of the controlling user and additional information during deferred invocation. That is important where the network needs to store or report user information as part of the service.

How related PICS forms are linked

Annex B repeats selected items from the basic call, generic functional protocol and supplementary services interactions PICS proformas. It uses conditional and optional status markers to show how this PICS depends on the base proformas.

For implementers, this means EN 300 745-2 is not used in isolation. It points back to the supporting PICS forms for basic call, generic functional protocol and supplementary service interactions, so those base forms also have to be completed where the service uses them.

What terms does SIST EN 300 745-2 V1.2.4:2005 define?

SIST EN 300 745-2 V1.2.4:2005 defines the main conformance-testing terms used in the PICS process.

• Protocol Implementation Conformance Statement (PICS) - A statement from the supplier that identifies which capabilities of an OSI protocol implementation are supported.
• PICS proforma - A questionnaire-style document that becomes a PICS when completed for a specific implementation.
• static conformance review - A comparison of the PICS against the static conformance requirements in the standard.
• Implementation Under Test (IUT) - The protocol implementation being checked for conformance.
• System Under Test (SUT) - The system in which the IUT resides during assessment.
• System Conformance Statement (SCS) - A related document that summarizes which OSI standards are implemented and the claimed level of conformance.
• DSS1 - Digital Subscriber Signalling System No. one, the signalling protocol used for the service.
• MWI - Message Waiting Indication, the supplementary service covered by the standard.

Who uses SIST EN 300 745-2 V1.2.4:2005?

SIST EN 300 745-2 V1.2.4:2005 is used by suppliers of ISDN equipment and software that claim conformance to EN 300 745-1. It is also used by test laboratories and conformance engineers who need a structured statement of supported features before selecting test cases.

Network operators, product managers and quality teams use it to check whether a user-side or network-side implementation supports the required MWI procedures, messages and timers. Buyers can use it to compare a vendor’s declared support with the roles and options that matter in their deployment.

What changed in SIST EN 300 745-2 V1.2.4:2005 from the previous edition?

Annex C states that this edition converts the document to EN layout, replaces references to ETS 300 102 with EN 300 403, replaces references to I-ETSs with EN 300 403, and updates non-specific references so they point to the latest version of the cited basic standards. The foreword also says the version updates the references to the basic call specifications.

Which standards are used with SIST EN 300 745-2 V1.2.4:2005?

SIST EN 300 745-2 V1.2.4:2005 depends on several related standards named in clause 2.

• EN 300 745-1 - The protocol specification for the ISDN DSS1 MWI supplementary service that the PICS describes.
• EN 300 196-1 - The protocol specification for the generic functional protocol supporting supplementary services.
• EN 300 196-2 - The PICS proforma for that generic functional protocol.
• EN 300 195-1 - The protocol specification for supplementary service interactions.
• EN 300 195-2 - The PICS proforma for supplementary service interactions.
• ISO/IEC 9646-1 - The general conformance-testing framework used for PICS concepts.
• ISO/IEC 9646-7 - The part that gives the guidance for Implementation Conformance Statements.
• CCITT Recommendation I.130 - The method for characterizing telecommunication services supported by an ISDN.
• ITU-T Recommendation I.411 - The reference configurations for ISDN user-network interfaces.

What does the SIST EN 300 745-2 V1.2.4:2005 document contain?

SIST EN 300 745-2 V1.2.4:2005 contains a completed-form structure rather than a protocol description. Annex A provides the tables for implementation identification, global conformance statements, role selection, user and network capabilities, facility information element components, timers and related support declarations.

Annex A also shows how to record support for procedures such as activation, deactivation and invocation, and how to mark support for return result and return error behavior. Annex B lists linked items from the basic call, generic functional protocol and supplementary services interactions PICS proformas so that the service can be assessed against the supporting protocol building blocks.

Annex C records the changes from the previous ETS 300 745-2. The result is a conformance form that is meant for documentation, design review, testing and conformance assessment, not for describing the user experience of the service itself.

Foreword
This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Signalling
Protocols and Switching (SPS).
The present document is part 2 of a multi-part standard covering the Digital Subscriber Signalling System No. one
(DSS1) protocol specification for the Integrated Services Digital Network (ISDN) Message Waiting Indication (MWI)
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: "Test Suite Structure and Test Purposes (TSS&TP) specification for the network";
Part 6: "Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (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).
The present version updates the references to the basic call specifications.

1 Scope
This second part of EN 300 745 is applicable to the stage three of the Message Waiting Indication (MWI)
supplementary service for the pan-European Integrated Services Digital Network (ISDN) as provided by European
public telecommunications operators at the T reference point or coincident S and T reference point (as defined in
ITU-T Recommendation I.411 [9]) by means of the Digital Subscriber Signalling System No. one (DSS1) protocol.
Stage three identifies the protocol procedures and switching functions needed to support a telecommunications service
(see CCITT Recommendation I.130 [8]).
The present document provides the Protocol Implementation Conformance Statement (PICS) proforma for the ISDN
DSS1 MWI supplementary service protocol as specified in EN 300 745-1 [5] in compliance with the relevant
requirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 [7].
The supplier of a protocol implementation which is claimed to conform to EN 300 745-1 [5] is required to complete a
copy of the PICS proforma provided in annex A of the present document and is required to provide the information
necessary to identify both the supplier and the implementation.
