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) Closed User Group (CUG)
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: "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 version updates the references to the basic call specifications.

1 Scope
This second part of EN 300 138 is applicable to the stage three of the Closed User Group (CUG) 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 [11]) 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 [10]).
The present document provides the Protocol Implementation Conformance Statement (PICS) proforma for the ISDN
DSS1 CUG supplementary service protocol as specified in EN 300 138-1 [2] in compliance with the relevant
requirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 [9].
The supplier of a protocol implementation which is claimed to conform to EN 300 138-1 [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.
2 Normative references
References may be made to:
a) specific versions of publications (identified by date of publication, edition number, version number, etc.), in

3 Definitions
For the purposes of the present document, the following definitions apply, in addition to those given in
EN 300 138-1 [2]:
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 [8]).
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 [8]).
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 [8]).

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 [8] 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.).
