Overview
SIST EN 300 122-2 V1.2.4:2005 is the Slovenian implementation of the European standard EN 300 122-2. This standard specifies the Protocol Implementation Conformance Statement (PICS) proforma for the Integrated Services Digital Network (ISDN) Generic Keypad Protocol using the Digital Subscriber Signalling System No. one (DSS1) protocol. As Part 2 of the multi-part standard for supplementary services in ISDN, this document details how to formally specify which protocol features and options are supported in specific ISDN implementations. The standard supports the evaluation and demonstration of conformance to protocol specifications, specifically referencing updates that now align with ETS 300 403 for core call-control protocols.
Key Topics
- Protocol Implementation Conformance Statement (PICS):
- A standardized proforma (questionnaire) that suppliers fill out to declare protocol capabilities and options in their ISDN equipment.
- Generic Keypad Protocol Support:
- Covers protocol features needed for keypad-based supplementary services, such as call waiting, call forwarding, and others.
- Roles and Functions:
- Addresses both user-side (terminal equipment) and network-side (exchange/provider) protocol capabilities.
- Conformance Assessment:
- How to complete the PICS for each implementation, including mandatory, optional, and conditional requirements.
- Reference Updates:
- Aligns references from previous standards (ETS 300 102-1 and related I-ETSs) to the newer ETS 300 403 call control specification.
- Supplementary Services:
- Ensures ISDN devices provide interoperability for additional features beyond the basic call, enabled through keypad signaling.
Applications
The PICS proforma provided in this standard has strong practical value for:
- ISDN Equipment Manufacturers: Demonstrating conformance of their terminal or network equipment to DSS1 supplementary services keypad protocol as required by European public telecommunications networks.
- Service Providers and Network Operators: Specifying and verifying feature support in procured or deployed ISDN equipment, thus enabling seamless supplementary service delivery.
- Conformance Testing and Certification: Formally documenting the supported features of an implementation, enabling objective static conformance reviews and streamlined interoperability testing.
- System Integrators and Buyers: Comparing product capabilities between different vendors, ensuring selection of devices that fully meet protocol requirements for supplementary services.
- Technical Auditing: Facilitating regulatory or internal audits for standards compliance in telecommunications infrastructure.
Related Standards
Several international and European standards are referenced to ensure comprehensive coverage and consistency:
- EN 300 122-1: Protocol specification for the ISDN generic keypad protocol (Part 1 of the series).
- EN 300 403-1: DSS1 network layer for circuit-mode basic call control (core protocol specification).
- EN 300 403-3: PICS proforma for DSS1 circuit-mode call control.
- ISO/IEC 9646-1 and ISO/IEC 9646-7: General framework and requirements for conformance testing and implementation statements.
- ITU-T Recommendations: I.130 (telecommunication service characterization), I.411 (ISDN user-network interface), and Q.932 (procedures for ISDN supplementary services).
Practical Value
Complying with SIST EN 300 122-2 V1.2.4:2005 allows organizations to ensure:
- Interoperability: Enabling their ISDN equipment to operate seamlessly across various public networks.
- Feature Transparency: Clearly documenting which supplementary services and protocol options are available, reducing deployment risks.
- Regulatory Compliance: Meeting European and international standards needed for market access and operation.

Foreword
This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Signalling
Protocols and Switching (SPS).
The present document 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) generic keypad protocol for the
support of supplementary services, as described below:
Part 1: "Protocol specification";
Part 2: "Protocol Implementation Conformance Statement (PICS) proforma specification".
NOTE: Further parts covering conformance testing may be identified later.
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).
The present version updates the references to the basic call specifications.

1 Scope
This second part of EN 300 122 is applicable to the stage three of the generic keypad protocol for the support of
supplementary services 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 [7]) 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 [6]).
The present document provides the Protocol Implementation Conformance Statement (PICS) proforma for the ISDN
DSS1 generic keypad protocol for the support of supplementary services as specified in EN 300 122-1 [2] in compliance
with the relevant requirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 [5].
The supplier of a protocol implementation which is claimed to conform to EN 300 122-1 [2] is required to complete a
copy of the PICS proforma provided in annex A of the present document and is required to provide the information
necessary to identify both the supplier and the implementation.

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 EN 300 122-1 [2];

Annex A (normative):
PICS proforma
Notwithstanding the provisions of the copyright clause related to the text of the present document, ETSI grants that users
of the present document 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 [4] is a document supplied by the client or product supplier that summarizes
which OSI International Standards, ITU-T (CCITT) Recommendations, ENs 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 for user implementations (including private network implementations) while
the Network clause shall only be completed for network implementations. The Roles subclause shall be completed for
all implementations.
The relationship between this PICS proforma and other related PICS proforma (e.g. the basic call PICS proforma) is
expressed in the Requirements List (RL) contained in annex B. This provides the additional restrictions placed on the
related proforma (different conditions, different status, etc.).
