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. two
(DSS2) protocol specification for the Broadband Integrated Services Digital Network (B-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: "TSS&TP specification for the network";
Part 6: "ATS and partial PIXIT proforma specification for the network".
NOTE: The final structure of the parts containing the test specifications is currently under
study.
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 300 770 is applicable to the stage three of the Closed User Group (CUG)
supplementary service for the pan-European Broadband Integrated Services Digital Network (B-ISDN) as
provided by European public telecommunications operators at the T reference point or coincident S and
B B
T reference point (as defined in ITU-T Recommendation I.413 [7]) by means of the Digital Subscriber
B
Signalling System No. two (DSS2) protocol. Stage three identifies the protocol procedures and switching
functions needed to support a telecommunications service (see CCITT Recommendation I.130 [6]).
This ETS provides the Protocol Implementation Conformance Statement (PICS) proforma for the B-ISDN
DSS2 CUG supplementary service protocol as specified in ETS 300 770-1 [3] 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 ETS 300 770-1 [3] 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.

This ETS incorporates by dated and undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications

3 Definitions
For the purposes of this ETS, the following definitions apply, in addition to those given in
ETS 300 770-1 [3]:
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 [4]).
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 [4]).
static conformance review: A review of the extent to which the static conformance requirements are met
by the Implementation Under Test (IUT), accomplished by comparing the PICS with the static
conformance requirements expressed in the relevant standard(s) (see ISO/IEC 9646-1 [4]).

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 [4] 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 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 contained in annex B. This provides the additional
restrictions placed o
