SIST EN 301 067-5 V1.2.1:2003 is the Slovenian adoption of ETSI EN 301 067-5 V1.2.1 for Broadband Integrated Services Digital Network (B-ISDN) signalling. It specifies the Test Suite Structure and Test Purposes (TSS&TP) for the network side of Digital Subscriber Signalling System No. two (DSS2) connection-characteristics negotiation during call and connection establishment.

The document is used when you need to test how a network implementation behaves at the TB reference point, or at coincident SB/TB reference points, against the DSS2 connection-negotiation rules.

What does SIST EN 301 067-5 V1.2.1:2003 specify?

SIST EN 301 067-5 V1.2.1:2003 specifies the conformance-test structure and the test purposes for network implementations of DSS2 connection-characteristics negotiation in B-ISDN. The document is organized as a short conformance-testing standard: scope, references, definitions and abbreviations, test suite structure, test purposes, compliance, and requirements for a comprehensive testing service.

Clause	What it covers
1	Scope
2	References
3	Definitions and abbreviations
4	Test Suite Structure (TSS)
5	Test Purposes (TP)
6	Compliance
7	Requirements for a comprehensive testing service

The scope is limited to the network Test Suite Structure and Test Purposes for implementations conforming to the signalling user-network layer 3 specification for connection negotiation during call and connection establishment. A further part of the EN provides the Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma.

What are the key requirements of SIST EN 301 067-5 V1.2.1:2003?

SIST EN 301 067-5 V1.2.1:2003 turns the base protocol specification into test purposes that check externally observable network behaviour. In practice, that means the document focuses on what the Implementation Under Test (IUT) sends, accepts, rejects, and in which call state it ends up.

Test purpose structure and naming

The test purposes are numbered within groups, and the naming convention identifies the suite, the group, and the test number. This matters because the TP names are used to map PICS items to test cases and to keep a test suite traceable.

Originating-interface negotiation

Clause 5 groups tests for traffic-parameter negotiation at the origination interface. These tests cover how a network entity reacts to SETUP messages carrying ATM traffic descriptor information, minimum acceptable traffic descriptor information, or alternative traffic descriptor information.

In practice, the tests check whether the network accepts valid combinations, rejects unsupported combinations, or adapts traffic parameters where negotiation is possible. They also check the handling of invalid information element contents and different protocol actions such as sending RELEASE COMPLETE or STATUS.

Destination-interface negotiation

Clause 5 also covers negotiation at the destination interface. The test purposes check that, when a call arrives with negotiation requested, the network sends a SETUP message that includes the relevant traffic descriptor information.

This matters for equipment that must forward negotiated traffic characteristics correctly on the network side, not just process them locally.

Acceptance and confirmation behavior

The acceptance tests verify what happens when the remote user answers the call. They check whether the network includes the negotiated ATM traffic descriptor in CONNECT or CONNECT ACKNOWLEDGE messages, and whether it preserves the original negotiated values when required.

Call-state handling

Many test purposes depend on the final call state after the exchange. The document uses the call-state enquiry procedure from EN 300 443-1 to confirm that the IUT has reached the expected state, such as N0, N1, N3, N4, N6, N7, N9, or N10.

Error handling and point-to-multipoint cases

The test purposes also check reactions to malformed or inconsistent CONNECT messages, including responses that report invalid information element contents or other protocol errors. Two tests address ADD PARTY handling when point-to-multipoint connection procedures are supported.

What terms does SIST EN 301 067-5 V1.2.1:2003 define?

• Abstract Test Method (ATM) - The testing approach used to exercise an implementation from outside its internal design.
• Abstract Test Suite (ATS) - The defined set of abstract test cases derived from the test purposes.
• Implementation Under Test (IUT) - The network implementation being checked for conformance.
• Protocol Implementation Conformance Statement (PICS) - The statement used to select applicable test cases for a specific implementation.
• Protocol Implementation eXtra Information for Testing (PIXIT) - Extra implementation-specific information needed to run the tests.
• Test Purpose (TP) - A statement of what a test case is intended to verify.
• ATM traffic descriptor - The information element that carries the traffic parameters being negotiated.

Who uses SIST EN 301 067-5 V1.2.1:2003?

SIST EN 301 067-5 V1.2.1:2003 is used by conformance test laboratories, network equipment vendors, and quality or certification teams working on B-ISDN/DSS2 implementations. It is relevant when they need to design, select, or execute tests for the network side of connection negotiation at the user-network interface. It also helps anyone preparing a PICS-based test campaign understand which behaviours need to be demonstrated.

What changed in SIST EN 301 067-5 V1.2.1:2003 from the previous edition?

SIST EN 301 067-5 V1.2.1:2003 aligns edition 1 of the standard with the TSS&TP for part 5 and corrects other possible errors based on contributions.

Which standards are used with SIST EN 301 067-5 V1.2.1:2003?

• EN 301 067-1 - Gives the protocol specification that the test purposes are based on.
• EN 301 067-2 - Provides the PICS proforma used to select relevant tests.
• ISO/IEC 9646-1 - Supplies the conformance-testing concepts used for terms such as ATS, ATM, IUT, PICS, PIXIT, and TP.
• ISO/IEC 9646-2 - Provides the abstract test suite specification framework and ATS compliance rules.
• ITU-T Recommendation I.413 - Defines the B-ISDN user-network interface reference points used in the scope.
• ETS 300 406 - Gives the testing methodology used to limit TPs to externally observable behaviour and realistic situations.
• EN 300 443-1 - Provides related DSS2 layer 3 definitions and the procedure used to verify call states.
• ITU-T Recommendation Q.2962 - Defines the connection-characteristics negotiation procedure covered by this standard.

What does the SIST EN 301 067-5 V1.2.1:2003 document contain?

The document contains a TSS diagram, TP naming rules, and a set of detailed test purposes for traffic-parameter negotiation on the network side. It includes procedures for valid and invalid SETUP, CONNECT, STATUS, RELEASE COMPLETE, ADD PARTY, and CONNECT ACKNOWLEDGE handling, with call-state checks tied to the expected outcomes. It also includes the compliance criteria for an ATS and a short requirement for organizations offering a comprehensive testing service.
