Overview
SIST ETS 300 058-2:1996 specifies the Protocol Implementation Conformance Statement (PICS) proforma for the Call Waiting (CW) supplementary service in the Integrated Services Digital Network (ISDN) environment, using the Digital Subscriber Signalling System No. one (DSS1) protocol. Developed by the Slovenian Institute for Standardization (SIST), this standard is aligned with European and international requirements. It applies to ISDN user-network interface layer 3, ensuring consistent implementation and testing of the CW supplementary service at both user and network sides. This document provides a key foundation for further implementation, testing, and specification work in conformance testing, such as PIXIT and ATS, as per ISO/IEC 9646 guidelines.
Key Topics
- ISDN Call Waiting (CW) Supplementary Service: Defines the protocol support and options for enabling the Call Waiting feature over ISDN, allowing users to be notified of incoming calls during an ongoing call.
- DSS1 Protocol Layer 3: Focuses on the user-network interface, specifically detailing implementation requirements for supplementary services using DSS1 at the T reference point or coincident S/T reference points.
- PICS Proforma Specification: Provides a structured, questionnaire-based approach for implementers to declare how their product supports the standard's requirements, including mandatory and optional features.
- Conformance Statement: Ensures implementations are in line with ETS 300 058-1 (the protocol specification), facilitating interoperability and certification.
- Roles and Capabilities: Details user-side and network-side roles, including key protocol capabilities such as handling of notifications, timers, and call states.
- Annexes and Requirements Lists: Offers reference checklists for implementers and testers, clarifying dependencies with related standards (e.g., basic call control, generic functional protocols).
Applications
Implementing SIST ETS 300 058-2:1996 delivers practical benefits for:
- Equipment Manufacturers: Provides a clear, standardized template for documenting compliance of ISDN devices and systems implementing call waiting supplementary services. This speeds up certification and market acceptance.
- Telecommunications Service Providers: Ensures networks support interoperable call waiting services when interconnecting with other public or private ISDN systems.
- Test Laboratories and Certification Bodies: The PICS proforma enables efficient and repeatable conformance assessment, as required for product certification and network compatibility.
- System Integrators and Purchasers: Facilitates objective evaluation of ISDN solutions for conformance with European and international telecommunication requirements.
The standard supports service definition at the protocol level, minimizing ambiguity and reducing integration risks in complex ISDN environments.

Foreword
This European Telecommunication Standard (ETS) has been produced by the Signalling Protocols and
Switching (SPS) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS is part 2 of a multi-part standard covering the Digital Subscriber Signalling System No. one
(DSS1) protocol specification for the Integrated Services Digital Network (ISDN) Call Waiting (CW)
supplementary service, as described below:
Part 1: "Protocol specification";
Part 2: "Protocol Implementation Conformance Statement (PICS) proforma specification";
Part 3: "Test Suite Structure and Test Purposes (TSS&TP) specification for the user";
Part 4: "Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing
(PIXIT) proforma specification for the user";
Part 5: "TSS&TP specification for the network";
Part 6: "ATS and partial PIXIT proforma specification for the network".
NOTE: The first part, ETS 300 058-1 (1991), containing the protocol specification, was initially
published as ETS 300 058 (1991) and has identical contents.
To evaluate conformance of a particular implementation, it is necessary to have a statement of which
capabilities and options have been implemented for a given Open Systems Interconnection (OSI)
protocol. Such a statement is called a Protocol Implementation Conformance Statement (PICS).

1 Scope
This second part of ETS 300 058 is applicable to the stage three of the Call Waiting (CW) supplementary
service for the pan-European Integrated Services Digital Network (ISDN) as provided by European public
telecommunications operators at the T reference point or coincident S and T reference point (as defined in
ITU-T Recommendation I.411 [12]) by means of the Digital Subscriber Signalling System No. one (DSS1)
protocol. Stage three identifies the protocol procedures and switching functions needed to support a
telecommunications service (see CCITT Recommendation I.130 [11]).
This ETS provides the Protocol Implementation Conformance Statement (PICS) proforma for the ISDN
DSS1 CW supplementary service protocol as specified in ETS 300 058-1 [1] in compliance with the
relevant requirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 [10].
The supplier of a protocol implementation which is claimed to conform to ETS 300 058-1 [1] is required to
complete a copy of the PICS proforma provided in annex A of this ETS and is required to provide the
information necessary to identify both the supplier and the implementation.

3 Definitions
For the purposes of this ETS, the following definitions apply, in addition to those given in
ETS 300 058-1 [1]:
Protocol Implementation Conformance Statement (PICS): A statement made by the supplier of an
Open Systems Interconnection (OSI) implementation or system, stating which capabilities have been
implemented for a given OSI protocol (see ISO/IEC 9646-1 [9]).
PICS proforma: A document, in the form of a questionnaire, designed by the protocol specifier or
conformance test suite specifier, which, when completed for an OSI implementation or system, becomes
the PICS (see ISO/IEC 9646-1 [9]).
static conformance review: A review of the extent to which the static conformance requirements are met
by the IUT, accomplished by comparing the PICS with the static conformance requirements expressed in
the relevant standard(s) (see ISO/IEC 9646-1 [9]).

5 Conformance
A PICS proforma which conforms to this PICS proforma specification shall be technically equivalent to
annex A, and shall preserve the numbering and ordering of the items in annex A.
A PICS which conforms to this PICS proforma specification shall:
a) describe an implementation which claims to conform to ETS 300 058-1 [1];
b) be a conforming ICS proforma which has been completed in accordance with the instructions for
completion given in clause A.1;
c) include the information necessary to uniquely identify both the supplier and the implementation.

Annex A (normative): PICS proforma
Notwithstanding the provisions of the copyright clause related to the text of this ETS, ETSI grants that
users of this ETS may freely reproduce the PICS proforma in this annex so that it can be used for its
intended purposes and may further publish the completed PICS.
A.1 Instructions for completing the PICS proforma
A.1.1 Identification of the implementation
Identification of the Implementation Under Test (IUT) and the system in which it resides (the System
Under Test (SUT)) should be filled in so as to provide as much detail as possible regarding version
numbers and configuration options.
The product supplier information and client information should both be filled in if they are different.
A person who can answer queries regarding information supplied in the PICS should be named as the
contact person.
The SCS as defined in ISO/IEC 9646-1 [9] is a document supplied by the client or product supplier that
summarizes which OSI International Standards, ITU-T (CCITT) Recommendations, ETSs or other
standards are implemented and to which conformance is claimed. The PICS/SCS subclause should
describe the relationship of the PICS to the SCS.
A.1.2 Global statement of conformance
If the answer to the statement in this subclause is "Yes", all subsequent subclauses should be completed
to facilitate selection of test cases for optional functions.
If the answer to the statement in this subclause is "No", all subsequent subclauses should be completed,
and all non-supported mandatory capabilities should be identified and explained. Explanations may be
entered in the comments field at the bottom of each table or on attached sheets of paper.
A.1.3 Explanation of PICS proforma subclauses
The PICS proforma contains a Roles clause and thereafter is presented in two parts (for user and
network) with the following subclauses, as required:
- major capabilities;
- subsidiary capabilities;
- protocol data unit support;
- protocol data unit parameters;
- timers;
- call states.
The User clause shall only be completed
