SIST EN 300 122-2 V1.2.4:2005 is the Slovenian adoption of ETSI EN 300 122-2 Version 1.2.4. It is a European Telecommunications Standard for the Integrated Services Digital Network (ISDN) generic keypad protocol in Digital Subscriber Signalling System No. one (DSS1), and it specifies the Protocol Implementation Conformance Statement (PICS) proforma used to declare which capabilities an implementation of EN 300 122-1 supports.

What does SIST EN 300 122-2 V1.2.4:2005 specify?

SIST EN 300 122-2 V1.2.4:2005 specifies the PICS proforma for stage three of the ISDN generic keypad protocol for supplementary services. It is written for implementations at the T reference point or at the coincident S and T reference point, and it tells a supplier how to state conformance to EN 300 122-1.

The document does not restate the protocol itself. Instead, it provides the conformance questionnaire, the rules for completing it, and a requirements list that links this PICS to the basic call PICS.

Annex	What it covers
Annex A	Normative PICS proforma, including completion instructions, identification fields, role selection, and user/network capability tables
Annex B	Normative requirements list that repeats selected basic call PICS items needed for support of EN 300 122-1
Annex C	Informative changes from the previous ETS 300 122-2

What are the key requirements of SIST EN 300 122-2 V1.2.4:2005?

SIST EN 300 122-2 V1.2.4:2005 is a conformance statement document, so its main requirement is administrative and structural: a completed PICS must match Annex A technically and keep the same numbering and ordering. In practice, that means a supplier cannot redesign the questionnaire - the completed form has to remain comparable with the standard.

Clause 5 says the PICS must describe an implementation that claims conformance to EN 300 122-1, must be completed according to Annex A, and must identify both the supplier and the implementation. This matters because the PICS is the record that supports a conformance claim and lets a tester or buyer know exactly what product is being described.

Identification and global statement

Annex A requires identification of the Implementation Under Test (IUT), the System Under Test (SUT), the product supplier, the client, and a contact person. The global conformance statement asks whether all mandatory requirements are met. If the answer is "No", the PICS must identify unsupported mandatory capabilities and explain them, which is how non-conformity is documented instead of hidden.

Roles and applicable sections

Annex A separates the PICS into a Roles clause, a User section, and a Network section. The Roles clause applies to all implementations, while the User tables are completed only for user implementations and the Network tables only for network implementations. In practice, this lets one standard cover both terminal-side and network-side equipment without mixing their requirements.

User capabilities

For user implementations, the document requires support for sending Keypad information for invoking a supplementary service. It also requires handling information received from the network to give indications to the requesting user. Optional items cover multiple generic protocols, automatic terminal reaction to received Keypad information, notifications to the remote user, en-bloc sending, overlap sending, and use of a sending complete indication.

These points matter because they tell the implementer whether the terminal can simply initiate a service, whether it must also interpret network feedback, and which optional user behaviors are claimed. The notes also link unsupported options to error recovery procedures in EN 300 403-1.

Network capabilities

For network implementations, Annex A requires support for receiving Keypad information used to invoke a supplementary service. It also covers optional support for multiple generic protocols per access, recognition of the user’s chosen protocol, handling service requests during call establishment, active call, and clearing phases, and handling registration, cancellation, activation, deactivation, or interrogation requests.

The network side also includes optional functions such as sending CALL PROCEEDING, prompting the user by messages or in-band tones and announcements, sending PROGRESS or INFORMATION messages with extra information, and deciding whether supplementary service information is complete from the received content or from a sending complete indication. In practice, these items show what the network can do when collecting, checking, and responding to service-related keypad data.

Basic call dependencies

Annex B ties this PICS to the basic call PICS items used with EN 300 122-1. It repeats the relevant message and information element items for user and network sides, including INFORMATION messages and the Keypad facility and Display information elements. This matters because a valid keypad protocol PICS depends on the related basic call PICS answers being completed in the base proforma.

What terms does SIST EN 300 122-2 V1.2.4:2005 define?

Protocol Implementation Conformance Statement (PICS) - A supplier’s statement showing which capabilities of a given OSI protocol have been implemented.

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

Implementation Under Test (IUT) - The implementation whose conformance is being examined.

System Under Test (SUT) - The system in which the IUT resides.

System Conformance Statement (SCS) - A document that summarizes which standards are implemented and to which conformance is claimed.

Static conformance review - A review that compares the PICS with the static conformance requirements in the relevant standard(s).

Who uses SIST EN 300 122-2 V1.2.4:2005?

SIST EN 300 122-2 V1.2.4:2005 is used by suppliers of ISDN DSS1 implementations who must complete a PICS for EN 300 122-1. It is also used by conformance testers, laboratories, and technical reviewers who need to check whether the claimed capabilities match the standard.

In practice, the document helps anyone preparing or checking a conformance claim for user-side or network-side equipment. It is also relevant to buyers and quality managers who need a structured statement of supported options before acceptance, testing, or deployment.

What changed in SIST EN 300 122-2 V1.2.4:2005 from the previous edition?

Annex C states four changes from the previous ETS 300 122-2: conversion to EN layout, replacement of references to ETS 300 102 with EN 300 403, replacement of references to I-ETSs with EN 300 403, and substitution of non-specific references to basic standards where the intent is to use the latest version. The foreword also says the present version updates the references to the basic call specifications.

Which standards are used with SIST EN 300 122-2 V1.2.4:2005?

Standard	What it contributes
EN 300 122-1	The protocol specification that this PICS proforma supports
EN 300 403-1	Basic call control signalling network layer reference used for related requirements
EN 300 403-3	Basic call PICS proforma that supplies the item numbering used in Annex B
ISO/IEC 9646-1	Conformance testing framework and general concepts for PICS use
ISO/IEC 9646-7	Guidance for Implementation Conformance Statements and their form
CCITT Recommendation I.130	Method for characterizing ISDN telecommunication services
ITU-T Recommendation I.411	ISDN user-network interface reference configurations
ITU-T Recommendation Q.932	Generic procedures for control of ISDN supplementary services

What does the SIST EN 300 122-2 V1.2.4:2005 document contain?

The document contains completion instructions, identification fields, a global conformance statement, and structured tables for roles, user capabilities, and network capabilities. It also includes a requirements list that cross-references items from the basic call PICS so that related answers stay aligned across documents.

Annex A is the main working part for conformance declaration. Annex B supports completion of the companion basic call PICS, and Annex C records the changes from the previous edition. Together, these parts support conformance assessment, supplier declarations, and selection of relevant test cases for optional functions.

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.

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
