SIST EN 300 267-2 V1.2.2:2005 is the Slovenian adoption of EN 300 267-2 Version 1.2.2 for Integrated Services Digital Network (ISDN) teleservices using the Digital Subscriber Signalling System No. one (DSS1). It specifies the Protocol Implementation Conformance Statement (PICS) proforma for telephony 7 kHz, videotelephony, audiographic conference and videoconference teleservices. In practice, it is the form suppliers fill in to state which protocol capabilities, options and roles a product supports before conformance assessment.
What does SIST EN 300 267-2 V1.2.2:2005 specify?
SIST EN 300 267-2 V1.2.2:2005 specifies the PICS proforma for stage three DSS1 protocol support of the ISDN teleservices named in the title. It is a conformance-documentation standard, not the protocol specification itself, and it is used together with EN 300 267-1.
The scope places it at the T reference point or coincident S and T reference point in pan-European ISDN provided by public telecommunications operators. The document also ties the proforma to the conformance-testing framework of ISO/IEC 9646-7.
| Annex | What it covers |
|---|---|
| Annex A | Normative PICS proforma for EN 300 267-1 |
| Annex B | Normative requirements list affecting the basic call PICS proforma |
| Annex C | Informative identification of changes from earlier standards |
The document is organized into clauses on scope, references, definitions, and conformance, followed by the annexes. That structure matters because the main body explains how to complete the PICS, while the annexes contain the actual answer forms and the related dependencies.
What are the key requirements of SIST EN 300 267-2 V1.2.2:2005?
SIST EN 300 267-2 V1.2.2:2005 requires a supplier claiming conformance to EN 300 267-1 to complete the PICS proforma in Annex A and identify both the supplier and the implementation. That gives test labs and buyers a single statement of what is implemented, which is what they need to compare against the standard.
Completion and identification
The PICS instructions in Annex A require clear identification of the Implementation Under Test (IUT) and System Under Test (SUT), plus product supplier, client and contact person details. In practice, this lets a conformance reviewer know exactly which product configuration is being described and who can answer questions.
The global statement of conformance asks whether all mandatory capabilities are implemented. If the answer is “No”, the form still has to identify unsupported mandatory items and explain them, so the resulting PICS can be reviewed for non-conformance.
Roles and supported service areas
Table A.1 defines the main roles and service areas to be declared: telephony 7 kHz, videotelephony, audiographic conference, videoconference, telephony 3,1 kHz, generic procedures, user requirements, network requirements, coincident S and T reference point support, and interworking with private ISDNs. This matters because many later questions in the PICS only apply if the implementation supports a given role or service.
For user and network implementations, the annex then breaks down the answers into major capabilities, subsidiary capabilities, protocol data unit support, protocol data unit parameters, timers and call states. That tells a supplier exactly where to record support for each feature rather than giving a single yes/no result.
Key capability areas to confirm
The most visible capability in both user and network tables is support for establishing a second connection within the same call, where the relevant conditions apply. This is important for videotelephony and conference-style use cases, where an implementation may need to manage more than one connection in a call.
Annex A also checks in-band protocol requirements. On the user side, it points to wideband telephony in I-ETS 300 245-5 and to audiovisual signalling in ETS 300 143 and ETS 300 145; on the network side, it includes in-band tones and announcements in accordance with CCITT Recommendation G.711 A-law when the bearer capability conditions apply. In practice, this is where a supplier shows how audio and video-related signalling is handled.
The tables also cover calling identification, connected identification, notification and status request procedures. These items matter because they are the call-control functions that often need to interwork with basic call procedures and supplementary services.
Relationship to the basic call PICS
Annex B repeats selected requirements from the basic call PICS proforma in EN 300 403-3 because they are affected by this document. The items concern Bearer Capability (BC) selection and High Layer Compatibility (HLC) selection on the user and network sides.
This annex is important because the answers in the base basic-call PICS depend on the service combination chosen here. A supplier completing the conformance statement therefore has to cross-check this document with the basic call PICS, not treat them as separate checklists.
What terms does SIST EN 300 267-2 V1.2.2:2005 define?
Protocol Implementation Conformance Statement (PICS) is the supplier’s statement of which capabilities of an OSI protocol implementation have been implemented.
PICS proforma is the questionnaire form that becomes a PICS when completed for a specific implementation.
Implementation Under Test (IUT) is the protocol implementation being examined for conformance.
System Under Test (SUT) is the system that contains the IUT and the configuration being declared.
System Conformance Statement (SCS) is the document that summarizes which OSI standards a system implements and claims conformance to.
Digital Subscriber Signalling System No. one (DSS1) is the signalling protocol family used here for ISDN call control and related teleservices.
Bearer Capability (BC) and High Layer Compatibility (HLC) are basic call items that the requirements list links to this PICS because they affect service selection and interworking.
Who uses SIST EN 300 267-2 V1.2.2:2005?
Suppliers of ISDN terminals, gateways and network implementations use this standard to complete the PICS for products that claim conformance to EN 300 267-1. That makes it useful during product definition, release documentation and customer acceptance.
Conformance testers and test laboratories use it to perform static conformance review, comparing the completed PICS with the requirements in the related standards. Network operators and buyers use it to check which teleservices, roles and options a product supports before deployment.
It is also relevant to engineering teams working on videotelephony, audiographic conference and videoconference signaling over DSS1, because the form shows which combinations of user and network behavior need to be declared.
What changed in SIST EN 300 267-2 V1.2.2:2005 from the previous edition?
The document is described as an extended and updated version of ETS 300 267-2 (1996). Annex C lists the main changes.
The update adds the new major roles for audiographic conference and videoconference, and it adds status conditions and references for those services throughout the document. It also removes older items that are now covered by EN 300 403-1 and EN 300 403-3, and introduces Annex B to show the requirements that affect answers in the basic call PICS.
Which standards are used with SIST EN 300 267-2 V1.2.2:2005?
EN 300 267-1 is the companion protocol specification that this PICS proforma applies to. EN 300 403-1 and EN 300 403-3 supply the basic call protocol and its own PICS proforma, which this document references through Annex B.
ISO/IEC 9646-1 and ISO/IEC 9646-7 provide the conformance testing framework and the rules for PICS documents. CCITT Recommendation I.130 and ITU-T Recommendation I.411 give the service characterization and ISDN reference configuration background.
ETS 300 092-1 and ETS 300 097-1 cover calling line and connected line identification presentation, while ETS 300 143, ETS 300 145 and I-ETS 300 245-5 support the audiovisual and 7 kHz telephony aspects used in the capability tables. EN 300 196-1 is also listed as a supporting DSS1 supplementary-services reference.
What does the SIST EN 300 267-2 V1.2.2:2005 document contain?
Annex A contains the completed-form structure, including tables for identification, global conformance, roles, user capabilities and network capabilities. It also provides the status and support columns that let a supplier mark whether each item is mandatory, optional, conditional, supported or not supported.
Annex B contains a requirements list that links this PICS to the basic call PICS in EN 300 403-3, especially for BC and HLC-related behavior. Annex C summarizes the changes from the earlier edition, which is useful when comparing product declarations across versions.
The document therefore serves as a working conformance form for documentation, comparison and test preparation, rather than as a protocol description or test suite.

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) telephony 7 kHz, videotelephony,
audiographic conference and videoconference teleservices, 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: "Test Suite Structure and Test Purposes (TSS&TP) specification for the network";
Part 6: "Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT)
proforma specification for the network".
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 document is an extended and updated version of ETS 300 267-2 (1996). Annex C identifies relevant
differences between the present document and this standard.

1 Scope
This second part of EN 300 267 is applicable to the stage three of the telephony 7 kHz, videotelephony, audiographic
conference and videoconference teleservices 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 [13]) 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
telecommunication service (see CCITT Recommendation I.130 [12]).
The present document provides the Protocol Implementation Conformance Statement (PICS) proforma for the ISDN
DSS1 protocol for the telephony 7 kHz, videotelephony, audiographic conference and videoconference teleservices and
associated generic procedures as specified in EN 300 267-1 [7] in compliance with the relevant requirements and in
accordance with the relevant guidance given in ISO/IEC 9646-7 [11].
The supplier of a protocol implementation which is claimed to conform to EN 300 267-1 [7] 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.
