SIST EN 302 093-3 V1.1.2:2005 is the Slovenian identical adoption of ETSI EN 302 093-3 V1.1.2 for Broadband Integrated Services Digital Network (B-ISDN) and the Digital Subscriber Signalling System No. two (DSS2) protocol. It specifies the Test Suite Structure and Test Purposes (TSS&TP) for point-to-point multiconnection bearer control in a separated call and bearer environment, for both the user and the network at the TB or coincident SB/TB reference points.

What does SIST EN 302 093-3 V1.1.2:2005 specify?

SIST EN 302 093-3 V1.1.2:2005 defines the conformance test structure and the individual test purposes for layer 3 bearer control. It supports implementations that conform to EN 302 093-1 and is the basis for the ATS and PIXIT proforma work in the next part.

The document is organized into clauses on scope, references, definitions and abbreviations, Test Suite Structure (TSS), Test Purposes (TP), compliance, and requirements for a comprehensive testing service. It also includes a bibliography and history.

What are the key requirements of SIST EN 302 093-3 V1.1.2:2005?

Clause 4 organizes the TSS around signalling procedures at the coincident SB/TB and TB reference points, with three test groups:

• preceding side
• succeeding side
• error handling

That structure matters because it tells a test lab where each behaviour is checked and helps a supplier map test cases to interface behaviour.

Clause 5.1 gives the TP naming convention. Each TP identifier includes the layer and type of IUT, the group number, and a sequence number. This makes test case selection traceable to the right part of the PICS proforma.

Clause 5.1.2 states that the TPs are based on EN 302 093-1, and clause 5.1.3 says they were generated by analysing the base standard and the PICS proforma. The TPs are limited to externally observable behaviour and realistic situations, so they are aimed at practical interoperability testing rather than internal design checks.

Clause 5.2 says separated bearer control builds on the basic call connection control procedures in EN 300443-1. The TP set covers only the extra procedures needed for multiconnection calls, which keeps this part focused on the bearer-control extension.

For the preceding side, the IUT must send the correct SETUP signalling when a bearer is added to a multiconnection call. For the succeeding side, the IUT must accept a valid SETUP and continue normal handling, while an unrecognized call association leads to call clearing behaviour.

The error-handling TPs check missing or malformed information elements and the action taken by the IUT. Depending on the case, the response is a RELEASE COMPLETE, a STATUS message, or no message, so implementers need to verify how their equipment reacts to bad signalling.

Clause 6 defines compliance for an ATS derived from this TSS&TP. A compliant ATS must:

• cover the relevant testable TPs
• use an appropriate subset of the TSS
• keep the same naming conventions
• preserve the link between PICS entries and test selection
• comply with ISO/IEC 9646-2

Clause 7 says that any organization offering a comprehensive testing service for user equipment claiming conformance to EN 302 093-1 shall use the Remote test method at minimum. That is the practical rule for test laboratories and conformance services.

What terms does SIST EN 302 093-3 V1.1.2:2005 define?

• Abstract Test Method (ATM) - the testing approach used to apply tests to an implementation under test in the conformance testing framework.
• Abstract Test Suite (ATS) - the complete set of abstract test cases used to check conformance.
• Implementation Under Test (IUT) - the equipment or implementation being tested.
• Protocol Implementation Conformance Statement (PICS) - the statement that identifies which features and options the implementation supports.
• Protocol Implementation eXtra Information for Testing (PIXIT) - extra implementation information needed to select and run tests correctly.
• Test Purpose (TP) - a statement of what one test is intended to verify.
• Lower tester - the test component that interacts with the IUT at the lower interface in the conformance setup.

Who uses SIST EN 302 093-3 V1.1.2:2005?

SIST EN 302 093-3 V1.1.2:2005 is used by conformance test developers, test laboratories, and equipment vendors working on DSS2 bearer control for B-ISDN. It is also relevant to quality managers and buyers who need to understand what a compliant test suite should cover before accepting user or network equipment.

Which standards are used with SIST EN 302 093-3 V1.1.2:2005?

• EN 302 093-1 - the protocol specification that the TPs are based on.
• EN 302 093-2 - the PICS proforma used to select the applicable tests.
• ISO/IEC 9646-1 - the conformance testing framework for concepts and definitions such as ATS, IUT, PICS, and PIXIT.
• ISO/IEC 9646-2 - the rules for Abstract Test Suite specification and testing methodology.
• ITU-T Recommendation I.413 - the reference for the B-ISDN user-network interface and its reference points.
• ETS 300406 - the methodology used for protocol and profile conformance test specifications.
• EN 300443-1 - the basic call connection control specification that separated bearer control builds on.

What does the SIST EN 302 093-3 V1.1.2:2005 document contain?

The document contains Figure 1 for the test suite structure and Table 1 for the TP identifier naming convention. Clause 5 lists the test purposes for preceding side, succeeding side, and error handling, with signalling examples centered on SETUP, RELEASE COMPLETE, and STATUS behaviour. Clause 6 defines ATS compliance rules, and clause 7 gives the minimum test method for a comprehensive testing service. The bibliography points to ISO/IEC 9646-3 for TTCN background.
