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".

1 Scope

This fourth part of ETS 300 402 provides the Protocol Implementation Conformance Statement (PICS)

proforma for the Integrated Services Digital Network (ISDN) Digital Subscriber Signalling System No. one

(DSS1) protocol data link layer general protocol as specified in ETS 300 402-2 [1] in compliance with the

relevant requirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 [3].

The supplier of an implementation that is claimed to conform to ETS 300 402-2 [1] is required to complete

a copy of the PICS proforma provided in annex A of this ETS.

The supplier of an implementation that is claimed to conform to annex ZA of ETS 300 402-2 [1] is required

to complete a copy of the PICS proforma provided in annex B of this ETS.

3 Definitions and abbreviations
3.1 Definitions

For the purposes of this ETS, the following definitions apply, in addition to those in ETS 300 402-2 [1],

ISO/IEC 9646-1 [2] and ISO/IEC 9646-7 [3]:

Implementation Conformance Statement (ICS): A statement made by the supplier of an implementation

or system claimed to conform to a given specification, stating which capabilities have been implemented.

The ICS can take several forms: protocol ICS, profile ICS, profile specific ICS, and information object ICS

(see ISO/IEC 9646-1 [2]).

network: The DSS1 protocol entity at the network side of the user-network interface.

Protocol Implementation Conformance Statement (PICS): An ICS for an implementation or system

claimed to conform to a given specification (see ISO/IEC 9646-1 [2]).

PICS proforma: A document, in the form of a questionnaire, which when completed for an

implementation or system becomes a PICS (see ISO/IEC 9646-1 [2]).
user: The DSS1 protocol entity at the user side of the user-network interface.

A PICS proforma that conforms to this PICS proforma specification shall be technically equivalent to either

annex A or annex B, and shall preserve the numbering and ordering of the items in annex A or annex B,

respectively.
A PICS that conforms to this PICS proforma specification shall:

a) describe an implementation which conforms to the main text or to annex ZA of ETS 300 402-2 [1] ;

b) be a conforming PICS proforma, which has been completed in accordance with the instructions for

completion given in clauses A.1 or B.1, respectively; and

c) include the information necessary to uniquely identify both the supplier and the implementation.

Annex A (normative): PICS proforma for ETS 300 402-2

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 300 402-2 [1] 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 [3].
Item column:

The item column contains a unique reference (a mnemonic plus a number) for each item within the PICS

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 proformas both these cases

were identified by the same mnemonic (e.g. MC).
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 300 402-4:1998
Page 10
ETS 300 402-4: September 1996
Status column:

The following notations, defined in ISO/IEC 9646-7 [3], are used for the status column:

M Mandatory - the capability is required to be supported.
O Optional - the capability may be supported or not.

N/A Not Applicable - in the given context, it is impossible to use the capability.

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 300 402-2 [1].
Reference column:

Except where explicitly stated, the reference column refers to the appropriate parts of ETS 300 402-2 [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 300 402-2 [1] 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 [3], 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 tick box, 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.

A.2 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 to provide as much detail as possible regarding version numbers

and configuration options.

The product supplier 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.
