SIST EN 301 492-1 V1.1.2:2005 is the Slovenian adoption of ETSI EN 301 492-1 V1.1.2. It defines the Test Suite Structure and Test Purposes (TSS&TP) for cordless terminal authentication supplementary services in Private Integrated Services Network (PISN) inter-exchange signalling, at the VPN "b" service entry point. It is intended for people who need conformance test cases for CTM authorization and related signalling behaviour.

What does SIST EN 301 492-1 V1.1.2:2005 specify?

SIST EN 301 492-1 V1.1.2:2005 specifies the TSS&TP for the cordless terminal authentication supplementary services of the inter-exchange signalling protocol for PISN. The document focuses on VPN scenarios at the "b" service entry point and uses ISO/IEC 9646 methodology as the basis for conformance testing.

The document is organized into clauses for scope, references, definitions and abbreviations, TSS, test purposes, compliance, and requirements for a comprehensive testing service. Clause 4 gives the test suite structure, clause 5 lists the individual test purposes, clause 6 states compliance conditions, and clause 7 gives a minimum requirement for comprehensive testing services.

What are the key requirements of SIST EN 301 492-1 V1.1.2:2005?

SIST EN 301 492-1 V1.1.2:2005 is mainly a test specification, so its key requirements are the structure of the tests and the expected signalling behaviour at each network role.

Test purpose naming and structure

Clause 5 defines a naming convention for test purposes: a service code, a group identifier, and a sequential number. In practice, this lets a test team select, trace, and report cases consistently across implementations.

Clause 5 also gives a fixed TP structure with stimulus, reaction, messages, information elements, and selection criteria. That matters because the same format is used across all test cases, which makes the suite easier to implement and compare.

Test strategy

Clause 5 states that the test purposes are derived from I-ETS 300809 and from the PICS specification. The test cases target externally observable behaviour and realistic situations, so they are suitable for conformance checks rather than internal design review.

SS-CTAT behaviour

Clause 5 covers SS-CTAT signalling at the Home PINX, Visitor PINX, and Authentication Server PINX, including initiation, requesting authentication parameters, fetching authentication parameters, and execution at the visitor side. The cases use APDUs, call states, and timers such as T1, T2, and T3, so a test lab must verify the right message exchange and timeout handling.

SS-CTAN behaviour

Clause 5 also covers SS-CTAN signalling at the Visitor PINX, Home PINX, and Authentication Server PINX. These cases check the handling of the challenge, authentication algorithm, calculated response value, and authentication session key, which tells a tester what information must be passed between network functions.

Interaction with SS-CTLR

Clause 5 includes protocol interaction between SS-CTAT and Cordless Terminal Location Registration (SS-CTLR) at the Previous Visitor PINX. This is important where authentication and location-registration procedures overlap.

Compliance

Clause 6 states that a compliant Abstract Test Suite (ATS) must include all testable test purposes, use an appropriate subset of the TSS, keep the naming conventions, preserve the PICS-to-test relationship, and comply with ISO/IEC 9646-2. In practice, this sets the minimum bar for an implementer or test house claiming conformance.

Comprehensive testing service

Clause 7 requires, at minimum, the Remote test method from ISO/IEC 9646-2 for any organization claiming a comprehensive testing service for equipment conforming to I-ETS 300808.

What terms does SIST EN 301 492-1 V1.1.2:2005 define?

• Abstract Test Suite (ATS) - A set of test cases derived from the test purposes for conformance testing.
• Implementation Under Test (IUT) - The system or equipment being checked against the test purposes.
• Protocol Implementation Conformance Statement (PICS) - The implementation statement used to select relevant test cases.
• Test Purpose (TP) - A single conformance objective written for a specific observable behaviour.
• Virtual Private Network (VPN) - The network scenario used for the "b" service entry point procedures.
• Private Integrated Services Network eXchange (PINX) - The exchange element used throughout the signalling procedures.
• Cordless Terminal Mobility (CTM) - The mobility context for the authentication supplementary services.

Who uses SIST EN 301 492-1 V1.1.2:2005?

SIST EN 301 492-1 V1.1.2:2005 is used by test laboratories, equipment vendors, conformance teams, and quality engineers working on PISN signalling equipment. It is especially relevant when building or reviewing test suites for CTM authentication, Home PINX and Visitor PINX behaviour, and authentication-server interactions.

It also helps buyers and technical assessors who need to know whether a product claim can be checked with standardized conformance tests.

What changed in SIST EN 301 492-1 V1.1.2:2005 from the previous edition?

The document history lists an earlier V1.1.1 edition and shows V1.1.2 as the published version of this standard. The history also records the adoption, voting, and publication timeline for V1.1.2.

Which standards are used with SIST EN 301 492-1 V1.1.2:2005?

The document relies on several referenced standards and companion documents, including:

• ETS 300239 - provides the generic functional protocol for supplementary services.
• ETS 300406 - gives the testing and specification methodology used as the conformance-testing basis.
• ISO/IEC 9646-1, -2, -3 - provide the conformance testing framework, abstract test suite method, and TTCN notation.
• EN 301060-1 - defines the VPN "b" service entry point and the VPN context.
• ETR 172 - gives VPN services and networking aspects.
• ETS 300692 - covers CTM location handling services and related terminology.
• I-ETS 300809 - is the base standard for the CTM supplementary services tested here.
• EN 300366 - provides a related conformance testing specification and methodology.
• ISO/IEC 11571 and ISO/IEC 11579-1 - support numbering and PISN exchange configuration.
• EN 300415 - supplies PISN terms and definitions.

The foreword also identifies Part 2 of this multi-part deliverable as the ATS and PIXIT proforma for the same VPN "b" service entry point.

What does the SIST EN 301 492-1 V1.1.2:2005 document contain?

SIST EN 301 492-1 V1.1.2:2005 contains the TSS in clause 4 and detailed TPs in clause 5, including naming rules, TP structure, and selection criteria. The document uses message flows, call states, APDUs, timers, and PICS references to describe expected behaviour for SS-CTAT and SS-CTAN.

Clause 5 also includes the interaction case with SS-CTLR and the behaviour at Previous Visitor PINX. Clause 6 turns the TP list into compliance rules for an ATS, and clause 7 states the minimum comprehensive testing method for organizations testing conformance claims.
