SIST EN 301 813-1 V1.1.1:2005 is a SIST standard based on the ETSI European Standard for the Integrated Services Digital Network (ISDN) and Broadband Integrated Services Digital Network (B-ISDN) Generic Addressing and Transport (GAT) protocol, Part 1: Protocol specification. It specifies how APDUs are passed between service provision points within a network, between networks, or between terminal equipment and networks. This ETSI text modifies ITU-T Recommendation Q.860 (2000) and is aimed at engineers and test teams working with ISDN and B-ISDN signalling.

What does SIST EN 301 813-1 V1.1.1:2005 specify?

SIST EN 301 813-1 V1.1.1:2005 specifies the GAT protocol for transferring APDUs in ISDN and B-ISDN signalling environments. It applies over DSS1, DSS2, SS#7, QSIG and B-QSIG, so implementers need to align the protocol with the signalling system they actually use.

Part / annex	What it covers
Part 1	Protocol specification
Part 2	Protocol Implementation Conformance Statement (PICS) proformaspecification
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) proformaspecification for the user
Annex A	Redirection function, informative

The foreword places Part 1 in a four-part series, so Part 1 is the protocol basis and the other parts support conformance work. Clause 1 also links the protocol to testing and to the Generic Functional Protocol defined in EN 300 196-1.

What are the key requirements of SIST EN 301 813-1 V1.1.1:2005?

SIST EN 301 813-1 V1.1.1:2005 is mainly about protocol encoding, naming, and the ETSI modifications to the ITU-T base text. For a reader, the important point is that the standard is not just descriptive - it fixes the protocol references and data element names that implementations and tests must use.

• Clause 1 extends the scope to testing and says the required capabilities depend on support for the Generic Functional Protocol defined in EN 300 196-1. In practice, a compliant implementation must support that protocol relationship, not just the GAT message flow.
• Clause 2 replaces the generic reference rule text and adds EN 300 196-1 as reference [12]. In practice, readers must treat the named reference as part of the document set when working to this standard.
• Throughout the text, references to ITU-T Recommendation Q.932 are replaced by EN 300 196-1. In practice, this keeps the ETSI terminology aligned with the referenced supporting protocol.
• Clause 8.2 updates table 1 and table 2 references for Addressing-Data-Elements and Facility-Information-Element-Components. In practice, implementers need to use the corrected element names when coding or validating protocol data.
• The endorsement notice also makes editorial corrections to the table titles and to specific wording such as singular and plural forms. In practice, this avoids transcription errors in technical documentation and test material.
• Appendix III changes the listed object identifier to the GAT-PDU form. In practice, protocol identification and interworking checks should use the corrected object identifier.
• Annex A is informative and covers the redirection function. In practice, it helps explain a related function without adding mandatory protocol rules.

What terms does SIST EN 301 813-1 V1.1.1:2005 define?

• APDU - Application Protocol Data Unit, the unit carried between service provision points.
• GAT - Generic Addressing and Transport, the protocol named in the title.
• Generic Functional Protocol - the supporting protocol named in clause 1 and linked to EN 300 196-1.
• DSS1 - Digital Subscriber Signalling System No. one, one of the signalling contexts where the protocol applies.
• DSS2 - Digital Subscriber Signalling System No. two, the broadband signalling context named in the scope.
• SS7 - Signalling System No. 7, the signalling system named in the foreword; the scope also writes SS#7.
• PICS - Protocol Implementation Conformance Statement, the proforma used to declare implementation capabilities.
• PIXIT - Partial Protocol Implementation eXtra Information for Testing, the implementation-specific test data used in testing.

Who uses SIST EN 301 813-1 V1.1.1:2005?

SIST EN 301 813-1 V1.1.1:2005 is used by telecommunications engineers, signalling protocol developers, equipment vendors, network operators, and conformance test laboratories. They use it when designing GAT support, checking interoperability over DSS1, DSS2, SS#7, QSIG or B-QSIG, and preparing PICS, TSS & TP, ATS, and PIXIT material.

What changed in SIST EN 301 813-1 V1.1.1:2005 from the previous edition?

SIST EN 301 813-1 V1.1.1:2005 is an ETSI modification of ITU-T Recommendation Q.860 (2000). The endorsement notice states these changes:

• Clause 1 adds a sentence linking later parts of the document set to testing and to the Generic Functional Protocol in EN 300 196-1.
• Clause 2 replaces the reference wording and adds EN 300 196-1 as reference [12].
• References to ITU-T Recommendation Q.932 are replaced by EN 300 196-1 throughout the text.
• Clause 8.2 updates the references in table 1 and table 2.
• Editorial corrections adjust the table titles, change "Component" to "Components", and correct "850" to "860".
• Appendix III changes the listed object identifier to the GAT-PDU form.
• Annex A is identified as informative.

Which standards are used with SIST EN 301 813-1 V1.1.1:2005?

Standard / part	What it contributes
EN 300 196-1 (V1.3)	Generic functional protocol for the support of supplementary services; clause 1 says GAT capabilities require its support
Part 2	PICS proformaspecification for the series
Part 3	TSS & TP specification for the user
Part 4	ATS and PIXIT proformaspecification for the user

These parts support implementation declaration and conformance testing alongside the protocol specification in Part 1.

What does the SIST EN 301 813-1 V1.1.1:2005 document contain?

The document contains the GAT protocol specification itself, plus ETSI modifications to the ITU-T base text. Clause 8.2 provides tables for Addressing-Data-Elements and Facility-Information-Element-Components, which are the technical building blocks used to encode and interpret protocol information. Appendix III gives the object identifier associated with the GAT-PDU. Annex A describes the redirection function in informative form, which is useful when reading or testing related protocol behavior.
