SIST EN 301 484-2 V1.1.1:2005

• Abstract:

  The Line Hunting supplementary service enables calls to a single ISDN number to be offered to a free access in a group of basic accesses. The Line Hunting supplementary service is intended for use on accesses to which terminals are connected at the S/T references point

SIST EN 301 484-2 V1.1.1:2005 is the Slovenian adoption of ETSI EN 301 484-2 for the ISDN Line Hunting (LH) supplementary service over DSS1. It specifies the Protocol Implementation Conformance Statement (PICS) proforma that suppliers use to state which LH capabilities and options their user or network implementation supports.

What does SIST EN 301 484-2 V1.1.1:2005 specify?

SIST EN 301 484-2 V1.1.1:2005 specifies how to document conformance claims for the Line Hunting supplementary service at stage three, for ISDN accesses at the T reference point or coincident S and T reference point. In practice, it is the checklist-style form used to record what a particular implementation supports so that conformance can be reviewed consistently.

The standard is organized into a short main body and two normative annexes.

Annex	What it covers
Annex A	The PICS proforma for EN 301 484-1, including identification, role selection, capability questions, protocol data units, parameters, timers and call states
Annex B	Requirements lists that relate the LH PICS to the base PICS proformas used for basic call, generic functional protocol and supplementary service interactions

The foreword also places this part within a six-part series: Part 1 is the protocol specification, Parts 3 and 4 cover user test suite material, and Parts 5 and 6 cover network test suite material.

What are the key requirements of SIST EN 301 484-2 V1.1.1:2005?

SIST EN 301 484-2 V1.1.1:2005 requires a completed PICS to match the structure of Annex A exactly and to keep the same numbering and order. This matters because conformance statements from different suppliers can then be compared item by item.

The standard also requires the completed PICS to describe an implementation that claims conformance to EN 301 484-1, to follow the completion instructions in clause A.1, and to identify both the supplier and the implementation. That makes the form usable as a traceable conformance record, not just a feature list.

Annex A completion rules

• The implementation section records the Implementation Under Test (IUT), the System Under Test (SUT), supplier details, client details and a contact person.
• The global conformance statement asks whether all mandatory capabilities are implemented. A "No" answer means unsupported mandatory capabilities must be identified and explained.
• The Roles clause applies to all implementations, while the User clause is completed only for user implementations and the Network clause only for network implementations.

Capability and parameter coverage

• For user implementations, Annex A covers major capabilities such as withdrawal from a Hunt Group, cancellation of withdrawal, and interrogation of the details of a Line Hunting supplementary service instance.
• For network implementations, Annex A covers provision, activation, deactivation, temporary withdrawal, cancellation of temporary withdrawal, interrogation of status, and invocation of the Line Hunting instance.
• Annex A also checks Facility information element components, including return result and return error items for each procedure, plus the corresponding invoke items.

Timers and interoperability points

• Annex A includes timers TM1, TM2 and TM3 with a stated value of 4 s for withdrawal, cancellation and interrogation procedures. In practice, this tells implementers what timing behavior the implementation is expected to support.
• Annex B ties the LH PICS to the base PICS proformas for the generic functional protocol and supplementary service interactions, so the LH form is used together with the related base forms when building a complete conformance statement.

What terms does SIST EN 301 484-2 V1.1.1:2005 define?

Protocol Implementation Conformance Statement (PICS) is a statement by a supplier that identifies which capabilities have been implemented for a given OSI protocol.

PICS proforma is the questionnaire-style document that becomes the PICS when it is completed for a specific implementation.

Static conformance review is the comparison of the PICS against the conformance requirements in the relevant standard.

Implementation Under Test (IUT) is the implementation being checked for conformance.

System Under Test (SUT) is the system that contains the IUT.

Line Hunting (LH) is the supplementary service covered by the standard.

Digital Subscriber Signalling System No. one (DSS1) is the signalling protocol used for the service.

Who uses SIST EN 301 484-2 V1.1.1:2005?

SIST EN 301 484-2 V1.1.1:2005 is used by suppliers of ISDN user and network implementations, by engineers preparing conformance claims, and by test teams that need a structured record of supported features. Quality managers and buyers use it to compare a supplier's declared support for LH functions against the expected protocol scope. Conformance testers use it to decide which optional functions, procedures, messages and timers apply to a given implementation.

What does the SIST EN 301 484-2 V1.1.1:2005 document contain?

SIST EN 301 484-2 V1.1.1:2005 contains a questionnaire-style PICS form in Annex A, with tables for roles, user functions, network functions, protocol data units, parameters and timers. It also contains Annex B, which maps this part to the underlying basic call, generic functional protocol and supplementary service interactions PICS material. The tables are designed for completion and review, so the document is used directly in conformance assessment and implementation documentation.
