SIST EN 300 403-3 V1.3.1:2005 is the Slovenian adoption of ETSI EN 300 403-3 for the Integrated Services Digital Network (ISDN) Digital Subscriber Signalling System No. one (DSS1) signalling network layer for circuit-mode basic call control. It specifies a Protocol Implementation Conformance Statement (PICS) proforma, so a supplier can declare which parts of EN 300 403-1 and EN 300 403-2 an implementation supports. Engineers, buyers, and conformance testers use it to document support for user and network roles, messages, information elements, timers, and compatibility options.

What does SIST EN 300 403-3 V1.3.1:2005 specify?

SIST EN 300 403-3 V1.3.1:2005 specifies the PICS proforma for the ISDN DSS1 signalling network layer for circuit-mode basic call control. Its purpose is to let a supplier state, in a standardized way, what an implementation supports for conformance assessment against EN 300 403-1 and EN 300 403-2.

The document is organized into four main clauses, then two annexes. Clause 1 gives the scope, Clause 2 lists references, Clause 3 defines terms and abbreviations, and Clause 4 states the conformance rules. Annex A is normative and contains the full PICS questionnaire; Annex B is informative and compares this proforma with the earlier ETS 300 102-1 version.

Annex	What it covers
Annex A	Normative PICS proforma for EN 300 403-1 and EN 300 403-2
Annex B	Informative differences from the PICS proforma for ETS 300 102-1

The stated scope is to update the Bearer Capability with new codepoints.

What are the key requirements of SIST EN 300 403-3 V1.3.1:2005?

SIST EN 300 403-3 V1.3.1:2005 is not a protocol behavior specification in itself. Its key requirement is that a conforming PICS must be technically equivalent to Annex A, keep the item numbering and order, and describe an implementation that conforms to EN 300 403-1 and EN 300 403-2.

Completing the PICS

Annex A requires the supplier to complete the questionnaire and provide support answers for each item. The answers use Yes, No, or N/A, with comments where needed. In practice, this means the PICS is the formal record of what the implementation actually supports.

Identifying the implementation and interface

Annex A asks for identification of the Implementation Under Test (IUT), the System Under Test (SUT), the product supplier, the client, and a contact person. It also ties each PICS to one physical interface type - Basic access or Primary rate access - and requires separate PICS entries when more than one interface or configuration is supported.

Separating user and network roles

Clause A.5 and later clauses split the questionnaire into user and network roles. Only the supported role needs to be completed, which matters because user-side and network-side behavior are tested differently in practice.

Covering the main protocol areas

Annex A asks about major capabilities such as call establishment, call clearing, restart, status enquiry, user signalling bearer service control, segmentation, D-channel backup, bearer service change, packet communications, and circuit-mode multirate connections. This lets a reader quickly see whether the implementation is aimed at basic telephony, extended services, or network-side behavior.

Describing messages, PDU parameters, and timers

The tables list received and transmitted messages, then drill down to Protocol Data Units (PDUs) and information elements. For received parameters, the document distinguishes transparent and non-transparent items such as Cause, Display, and Keypad facility, which matters because some items must be passed upward even when the protocol does not act on them. Annex A also lists timers and the supported values, including timers such as T301, T305, T308, T309, and T322.

Defining compatibility and numbering structures

Annex A includes detailed structures for the Bearer capability, High layer compatibility, Low layer compatibility, and Calling Party Number/Called Party Number information elements. In practice, these tables are where a supplier declares transfer mode, transfer rate, coding, layer support, numbering plan, presentation, and screening behavior - the details that affect interoperability.

What terms does SIST EN 300 403-3 V1.3.1:2005 define?

• Implementation Conformance Statement (ICS) - a supplier’s statement of which capabilities are implemented for a given specification.
• Protocol Implementation Conformance Statement (PICS) - an ICS for a protocol implementation or system claimed to conform to a specification.
• PICS proforma - the questionnaire form that becomes a PICS when completed.
• IUT - the Implementation Under Test, meaning the specific implementation being described.
• SUT - the System Under Test, meaning the system in which the IUT resides.
• DSS1 - Digital Subscriber Signalling System No. one, the signalling protocol family covered here.
• BC - Bearer Capability information element.

Who uses SIST EN 300 403-3 V1.3.1:2005?

SIST EN 300 403-3 V1.3.1:2005 is used by suppliers of ISDN DSS1 equipment, such as terminals, private automatic branch exchanges (PABX), and network-side implementations. It is also used by conformance test engineers, quality managers, and buyers who need a structured declaration of supported protocol features before interoperability testing or acceptance.

It is especially useful when a product may support only some user or network roles, some access types, or only selected bearer and compatibility options. That makes it a practical document for comparing implementations and planning test coverage.

What changed in SIST EN 300 403-3 V1.3.1:2005 from the previous edition?

SIST EN 300 403-3 V1.3.1:2005 is described as an extended and updated version of ETS 300 102-2, and it is based on ITU-T Recommendation Q.931 (1993). Annex A identifies the relevant differences from ETS 300 102-2, and Annex B describes differences from the earlier PICS proforma for ETS 300 102-1. The scope also states that the Bearer Capability is updated with new codepoints.

Which standards are used with SIST EN 300 403-3 V1.3.1:2005?

• EN 300 403-1 - defines the protocol specification that the PICS refers to.
• EN 300 403-2 - provides the Specification and Description Language (SDL) diagrams that support the protocol description.
• ISO/IEC 9646-7 - gives the guidance for Implementation Conformance Statements used by the PICS proforma.
• ISO/IEC 9646-1 - provides the general conformance testing framework and terminology.
• ITU-T Recommendation Q.931 - is the base protocol specification on which EN 300 403-1 is derived.
• ETS 300 102-1 and ETS 300 102-2 - are the earlier related versions used for comparison in the foreword and Annex B.

What does the SIST EN 300 403-3 V1.3.1:2005 document contain?

Annex A contains the full questionnaire-style proforma, with blank fields for supplier, client, IUT, SUT, and contact details, plus the role selection and conformance statements. It then provides large tables for user-role and network-role capabilities, message reception and transmission, and information elements in each message type.

The annex also includes detailed tables for timers, Bearer capability structure, High layer compatibility, Low layer compatibility, and numbering information elements. These tables are the practical core of the document, because they show exactly what a supplier must declare for interoperability review and conformance testing.
