SIST EN 301 453-1 V1.1.2:2005 is the SIST adoption of the ETSI European Standard for Private Integrated Services Network (PISN) inter-exchange signalling protocol diversion supplementary services. It specifies the Test Suite Structure and Test Purposes (TSS&TP) for call diversion services, so implementers can check conformance and interoperability for SS-DIV in VPN scenarios at the “b” service entry point.

What does SIST EN 301 453-1 V1.1.2:2005 specify?

SIST EN 301 453-1 V1.1.2:2005 defines the test purposes and test-suite structure for the diversion supplementary services of the PISN inter-exchange signalling protocol. The document is intended to support conformance tests that better reflect real interworking needs, and it limits the tests to VPN scenarios at the “b” service entry point.

The document is organized as a TSS in clause 4 and a set of TPs in clause 5, followed by compliance criteria in clause 6 and a requirement for a comprehensive testing service in clause 7. Part 1 is this TSS&TP specification; Part 2 is identified as the Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma.

What are the key requirements of SIST EN 301 453-1 V1.1.2:2005?

Clause 5 builds the test purposes from the base standard ETS 300257 and from the Protocol Implementation Conformance Statement (PICS). The practical point is that the test purposes are tied to what an implementation actually declares support for, so a tester can select only the relevant cases.

TP structure and selection

Clause 5.1 gives the TP naming convention and structure. Each TP is numbered within its group, and the group follows the TSS organization. In practice, this makes it easier to trace a test case back to a service and a call-handling situation.

Clause 5.1.4 says the TP set is based on externally observable behavior of the Implementation Under Test (IUT) and on conceivable situations an implementation is likely to face. It also states that TPs are mandatory unless they have selection criteria linked to configuration options in the PICS.

Originating PINX and Served User PINX behavior

Clause 5.2.1 covers signaling procedures at the Originating PINX for SS-CFU, SS-CFB and SS-CFNR. These tests check that the IUT accepts diversion-related APDUs in FACILITY or CONNECT messages and moves into the right call or diversion state. For a tester, this means verifying both message handling and state transitions.

Clause 5.2.2 covers activation, deactivation, interrogation and invocation at the Served User PINX. It includes use of activateDiversionQ, deactivateDiversionQ and interrogateDiversionQ, plus checks on diverted-to number verification. In practice, the implementation must return the right result or error, and in some cases place a checkRestriction request toward the Diverted-to PINX.

Rerouteing and diverted-to handling

Clause 5.2.3 covers the Rerouteing PINX. It specifies how callRerouteing invoke and return APDUs are exchanged, how the diverted leg is set up, and how the original and optional parameters are encoded. For CFNR, it also includes the behavior when the diversionCounter reaches the maximum value and how the system reacts to diverted-leg failure.

Clause 5.2.4 covers the Diverted-to PINX. These tests verify that a diverted call is accepted and that checkRestriction requests are answered correctly, including error handling for invalid basic service, diverted-to number or served user number. This matters because the diverted destination must be checked before the call is completed.

Activation, deactivation and interrogation procedures

Clauses 5.2.5 to 5.2.7 cover the Activating PINX, Deactivating PINX and Interrogating PINX. The tests use SETUP(sc) and the corresponding return result, return error or reject APDUs, with timeouts such as T2. In practice, these clauses check the management side of the service, not just call forwarding during live calls.

Interactions with other supplementary services

Clause 5.2.8 covers interactions with SS-CCBS, SS-CCNR and SS-CT. These tests check how SS-DIV behaves when combined with other supplementary services and additional network features. This is important for interoperability, because real networks often enable more than one service at the same time.

What terms does SIST EN 301 453-1 V1.1.2:2005 define?

• Implementation Under Test (IUT) - The system, exchange or user equipment being tested for conformance.
• Protocol Implementation Conformance Statement (PICS) - The statement used to declare which options and features an implementation supports.
• Abstract Test Suite (ATS) - The abstract test cases that are derived from the TPs for conformance testing.
• Test Purpose (TP) - A statement of the behavior to be checked by a test case.
• Test Suite Structure (TSS) - The organization of the test purposes into groups and call scenarios.
• SS-DIV - The diversion supplementary services covered by the document.
• SS-CFU, SS-CFB, SS-CFNR - Call forwarding unconditional, call forwarding busy and call forwarding no reply supplementary services.

Who uses SIST EN 301 453-1 V1.1.2:2005?

SIST EN 301 453-1 V1.1.2:2005 is used by protocol implementers, interoperability test labs, equipment vendors and quality teams working on PISN and VPN signaling. It helps them define what to test, choose the relevant PICS-dependent cases, and check how an implementation handles diversion, rerouteing and related supplementary-service interactions.

Which standards are used with SIST EN 301 453-1 V1.1.2:2005?

The document uses ETSI ETS 300257 as the base standard for the diversion supplementary services it tests. It relies on ISO/IEC 9646-1, ISO/IEC 9646-2 and ISO/IEC 9646-3 for the conformance-testing methodology and the TTCN approach. ETSI EN 301 060-1 and ETR 172 define the VPN “b” service entry point used to limit the scenarios. ETSI ETS 300406 provides the standardization methodology for protocol and profile conformance test specifications. ETSI I-ETS 300808 is named in clause 7 as the reference for the comprehensive testing service statement.

What does the SIST EN 301 453-1 V1.1.2:2005 document contain?

The document contains a TSS table, TP naming conventions, and a large set of test purposes grouped by call role and service. It includes procedures for the Originating PINX, Served User PINX, Rerouteing PINX, Diverted-to PINX, Activating PINX, Deactivating PINX and Interrogating PINX.

It also contains test purposes for protocol interactions between SS-DIV and SS-CCBS, SS-CCNR and SS-CT. Clause 6 states the rules for a compliant ATS, including use of an appropriate subset of the TSS and the same naming conventions.
