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 3 of a multi-part standard covering the Digital Subscriber Signalling System No. one
(DSS1) protocol specification for the Integrated Services Digital Network (ISDN) signalling network layer
for circuit-mode basic call control, as described below:
Part 1: "Protocol specification";
Part 2: "Specification and Description Language (SDL) diagrams";
Part 3: "Protocol Implementation Conformance Statement (PICS) proforma specification";
Part 4: "Test Suite Structure and Test Purposes (TSS&TP) specification for the user";
Part 5: "Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing
(PIXIT) proforma specification for the user";
Part 6: "TSS&TP specification for the network";
Part 7: "ATS and partial PIXIT proforma specification for the network".
Transposition dates
Date of adoption of this ETS: 6 September 1996
Date of latest announcement of this ETS (doa): 31 December 1996
Date of latest publication of new National Standard
or endorsement of this ETS (dop/e): 30 June 1997
Date of withdrawal of any conflicting National Standard (dow): 30 June 1997
Introduction
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 an Implementation Conformance Statement (ICS). An ICS stating
what capabilities and options have been implemented for a particular protocol is called a protocol ICS.
This is commonly abbreviated to "PICS".
ETS 300 403-1 is derived from ITU-T Recommendation Q.931 (1993). However, no PICS proforma exists
for this Recommendation. Therefore, ETSI has created a PICS proforma that is specific to the European
environment. This PICS proforma reflects the requirements contained in ITU-T Recommendation Q.931
with the modifications applied by ETS 300 403-1 [1]. This has been done to assist understanding of how
the European requirements relate to the requirements contained within ITU-T Recommendation Q.931
(and in particular, to the options specified in that Recommendation that are selected by the ETS). In
practical terms, this means that a number of capabilities specified by ITU-T Recommendation Q.931
appear as items in this PICS proforma with a status more akin to the status that would be expected in a
profile ICS (i.e. out-of-scope (I), prohibited (X)).
Annex B of this ETS describes the differences between the proforma contained in annex A and the
proforma for the earlier version of the DSS1 protocol as specified in ETS 300 102-1 (1990).

1 Scope
This third part of ETS 300 403 provides the Protocol Implementation Conformance Statement (PICS)
proforma for the Integrated Services Digital Network (ISDN) Digital Subscriber Signalling System No. one
(DSS1) protocol signalling network layer for circuit-mode basic call control as specified in
ETS 300 403-1 [1] and ETS 300 403-2 [2] in compliance with the relevant requirements and in accordance
with the relevant guidance given in ISO/IEC 9646-7 [4].
Both the packet communication procedures (see clause 6 of ETS 300 403-1 [1]) and the User Signalling
Bearer Service (USBS) procedures (see clause 7 of ETS 300 403-1 [1]) are excluded from this PICS
proforma.
The supplier of an implementation that is claimed to conform to ETS 300 403-1 [1] and ETS 300 403-2 [2]
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.

Annex A (normative): PICS proforma for ETS 300 403-1 and ETS 300 403-2
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 Guidance for completing the PICS proforma
A.1.1 Purpose and structure
The purpose of this PICS proforma is to provide a mechanism whereby a supplier of an implementation of
the requirements defined in ETS 300 403-1 [1] and ETS 300 403-2 [2] may provide information in a
standardized manner.
The PICS proforma is subdivided into clauses as follows:
A.1: instructions for completing the various parts of the PICS proforma;
A.2: identification of the implementation;
A.3: identification of the protocol to which this PICS proforma applies;
A.4: explanation of the PICS proforma tables;
A.5: global statement of conformance;
A.6: questions to determine roles;
A.7: questions for the user role; and
A.8: questions for the network role.
A.1.2 Symbols, abbreviations and conventions
The PICS proforma contained in this annex is comprised of information in tabular form in accordance with
the guidelines presented in ISO/IEC 9646-7 [4].
Item column:
The item column contains a unique reference (a mnemonic plus a number) for each item within the PICS
proforma.
NOTE: Where possible, backwards compatibility has been maintained between the item
references used in this PICS proforma and those used in the PICS proforma for the
earlier version of the DSS1 protocol described in ETS 300 102-1.
In general, the same mnemonics have been used in this PICS proforma as in earlier proforma. An
additional lower case letter has been added to differentiate PICS items related to the user role (e.g. MCu)
and PICS items related to the network role (e.g. MCn). In earlier PICS proforma both these cases were
identified by the same mnemonic (e.g. MC).
A further consequence of maintaining backwards compatibility is the appearance of discontinuities in the
numeric part of the item reference. There are, for example, PICS items listed as messages transmitted by
the network with the references "MTn 2" and "MTn 4"; the reference between, "MTn 3" is not used.
Item description column:
The item description contains a brief summary of the static requirement for which a support answer is
required.
Conditions for status column:
The conditions for status column contains a specification, if appropriate, of the predicate upon which a
conditional status is based.
---------------------- Page: 11 ----------------------
SIST ETS 300 403-3:1998
Page 10
ETS 300 403-3: September 1996
Status column:
The following notations, defined in ISO/IEC 9646-7 [4], are used for the status column:
I Irrelevant or out-of-scope - this capability is outside the scope of the ETS to
which this PICS proforma applies and is not subject to conformance testing in
this context.
M Mandatory - the capability is required to be supported.
N/A Not Applicable - in the given context, it is impossible to use the capability. No
answer in the support column is required.
O Optional - the capability may be supported or not.
O.i qualified optional - for mutually exclusive or selectable options from a set. "i" is
an integer that identifies an unique group of related optional items and the logic
of their selection, defined below the table.
X eXcluded or prohibited - there is a requirement not to use this capability in a
given context.
NOTE: To support a capability means that the capability is implemented in conformance to
ETS 300 403-1 [1] and ETS 300 403-2 [2].
Reference column:
Except where explicitly stated, the reference column refers to the appropriate parts of ETS 300 403-1 [1]
describing the particular item.
NOTE: A reference indicates only the location of the most essential information about an item.
All additional requirements contained in ETS 300 403-1 [1] and ETS 300 403-2 [2]
have also to be taken into account when making a statement about the conformance
of that particular item.
Support column:
The following notation, defined in ISO/IEC 9646-7 [4], is used for the support column:
[ ] Yes [ ] No Tick "Yes" if item is supported, tick "No" if item is not supported.
[ ] N/A Tick "N/A" if the item is "not applicable".
Prerequisite line:
A prerequisite line takes the form: Prerequisite: .
A prerequisite line after a subclause heading or table title indicates that the whole subclause or the whole
table is not required to be completed if the predicate is FALSE.
A.1.3 Instructions for completing the PICS proforma
The supplier of the implementation shall complete the PICS proforma. For each row in each PICS
proforma table the supplier shall enter an explicit answer (i.e. by ticking the appropriate "Yes", "No", or
"N/A" in each of the support column boxes provided. Where a support column box is left blank, or where it
is marked "N/A" without any tickbox, no answer is required. If necessary, the supplier may enter additional
comments at the end of each table, or separately.
More detailed instructions may be found at the beginning of each subclause of the proforma.
