SIST EN 301 068-5 V1.1.2:2003 is the network-side Test Suite Structure and Test Purposes (TSS&TP) specification for the Broadband Integrated Services Digital Network (B-ISDN) Digital Subscriber Signalling System No. two (DSS2) protocol for ATM transfer capability and traffic parameter indication. It is the Slovenian adoption of ETSI EN 301 068-5 and is used to test network implementations at the TB reference point, or the coincident SB/TB reference point, against EN 301 068-1. It is written for people who need to derive, select, or run conformance tests for network equipment.

What does SIST EN 301 068-5 V1.1.2:2003 specify?

SIST EN 301 068-5 V1.1.2:2003 specifies the network TSS&TP for implementations conforming to the signalling user-network layer 3 specification in EN 301 068-1. The standard focuses on the network side of the user-network interface, which matters in practice because it defines what a network implementation should do when it receives or sends DSS2 messages for ATM transfer capability and traffic parameter indication.

The document is organized into:

• scope
• references
• definitions and abbreviations
• Test Suite Structure (TSS)
• Test Purposes (TP)
• compliance
• requirements for a comprehensive testing service

Table 1 defines the TP naming convention, and Figure 1 shows the test suite structure.

What are the key requirements of SIST EN 301 068-5 V1.1.2:2003?

Clause 4 defines the TSS as two main families of procedures: signalling procedures at the coincident SB/TB and TB reference points, and additional parameter procedures at the originating and destination interfaces. In practice, this tells a test designer how the cases are grouped and where each case applies.

Clause 5 states that each TP is defined for one test requirement and numbered within its group. The TP identifier format ties the suite, group, and sequence together, which matters when you select tests from a PICS proforma or trace a failure back to a specific requirement.

Clause 5 also says the TPs are based on EN 301 068-1 and the PICS specification EN 301 068-2, and that they focus on externally observable behaviour and realistic situations. In practice, the document is intended for conformance testing, not for internal implementation checks.

The network TPs cover these main areas:

• Sustainable Cell Rate parameter set
• traffic management option for support of tagging
• Broadband Bearer Capability
• Available Bit Rate (ABR) set-up parameter
• ATM Block Transfer (ABT) capability
• handling of error conditions

These groups matter because they describe the message sequences and outcomes a network implementation should show, such as CALL PROCEEDING, CONNECT, CONNECT ACKNOWLEDGE, RELEASE COMPLETE, or STATUS.

Several TPs check call-state behaviour. Clause 5.1.4 explains that when a TP refers to a final call state, the implementation is checked by the STATUS ENQUIRY and STATUS exchange described in EN300443-1. In practice, the tester must verify not only the message, but also the call state reached by the network entity.

Clause 6 sets the compliance rule for an Abstract Test Suite (ATS). A compliant ATS must use a TSS consistent with clause 4, keep the TP naming and grouping rules, preserve the link between TPs and PICS items, and follow ISO/IEC 9646-2. This matters because it tells a test author how much of the suite must be retained and how the tests must be structured.

Clause 7 says that any organization claiming to provide a comprehensive testing service for network equipment conforming to EN 301 068-1 shall use the Remote test method from ISO/IEC 9646-2. That is the practical baseline for service providers running conformance tests.

What terms does SIST EN 301 068-5 V1.1.2:2003 define?

• Abstract Test Suite (ATS) - the set of abstract test cases built from the TPs and used as the basis for executable conformance tests.
• Abstract Test Method (ATM) - the conformance-testing method used to define how the abstract tests are applied.
• Implementation Under Test (IUT) - the network implementation being checked for conformance.
• Protocol Implementation Conformance Statement (PICS) - the proforma used to describe implementation options and select applicable tests.
• Protocol Implementation eXtra Information for Testing (PIXIT) - additional implementation data needed to parameterize testing.
• network (SB/TB) - the DSS2 protocol entity at the network side of the user-network interface where the coincident SB/TB reference point applies.
• ABT-IT - ATM block transfer with delayed transmission.
• ABT-DT - ATM block transfer with immediate transmission.

Who uses SIST EN 301 068-5 V1.1.2:2003?

Telecommunications equipment manufacturers use this standard to build conformance tests for network-side DSS2 behaviour. Test laboratories use it to derive ATS test cases and to check message sequences, call-state transitions, and error handling.

Quality and certification teams use it to map PICS answers to applicable test purposes and to document whether a network implementation meets EN 301 068-1. It is also relevant to organizations that provide remote conformance testing services for B-ISDN network equipment.

What changed in SIST EN 301 068-5 V1.1.2:2003 from the previous edition?

This edition is V1.1.2 and follows V1.1.1, which is listed in the document history. The history identifies the earlier publication but does not add a change summary.

Which standards are used with SIST EN 301 068-5 V1.1.2:2003?

ISO/IEC 9646-2	Abstract Test Suite specification and conformance-testing methodology.
ITU-T I.413	The B-ISDN user-network interface reference points used in the scope.
ETS 300 406	Testing methodology and the realism of test situations.
EN 300 443-1	Call states and the STATUS ENQUIRY/STATUS procedure used in TP execution.
ITU-T Q.2961, Q.2961.1, Q.2961.2, Q.2961.3, Q.2961.4	Additional traffic parameters and the tagged, ABR, and ABT signalling capabilities referenced by the TPs.

What does the SIST EN 301 068-5 V1.1.2:2003 document contain?

The document contains a TSS with a simple hierarchy of test groups and a TP naming scheme, plus a figure that maps the suite structure. Clause 5 then gives the individual TPs for originating and destination interface behaviour, including normal call set-up, parameter exchange, and error handling.

It also contains detailed message-based test purposes for ATM transfer capability and traffic parameter indication, including cases for accepted, adjusted, rejected, or incomplete message contents. These are used to build conformance tests for design verification and formal testing.

Clauses 6 and 7 turn the TP set into a usable testing framework by defining ATS compliance and the minimum remote test method for comprehensive testing services.
