Annex A (normative): PICS proforma for ETS 300 009-1
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 Purposes 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 300 009-1 [1] may provide information about the implementation in a
standardized manner.
The PICS proforma is subdivided into clauses for the following categories of information:
- guidance for completing the PICS proforma;
- identification of the implementation;
- identification of the protocol;
- global statement of conformance;
- explicit statements about the implemented capabilities.
A.1.2 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 number which identifies the item in the table.
Item description column
The item description column describes in free text each respective item (e.g. parameters, timers, etc.). It
implicitly means "is supported by the implementation?".
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.
x prohibited (excluded) - there is a requirement not to use this capability in the
given context.
o.i qualified optional - for mutually exclusive or selectable options from a set. "i" is
an integer which identifies an unique group of related optional items and the
logic of their selection which is defined immediately following the table.
ci conditional - the requirement on the capability ("m", "o", "x" or "n/a") depends on
the support of other optional or conditional items. "i" is an integer identifying an
unique conditional status expression which is defined immediately following the
table.

---------------------- Page: 11 ----------------------

SIST ETS 300 009-2:1998
Page 10
ETS 300 009-2: September 1996
Reference column
The reference column gives reference to ITU-T Recommendations Q.711 to Q.714 as modified by
ETS 300 009-1 [1], except where explicitly stated otherwise.
Note, however, that a reference merely indicates the place where the core of a description of an item can
be found. Any additional information contained in ETS 300 009-1 [1] needs to be taken into account when
making a statement about the conformance of that particular item.
Support column
The support column shall be filled in by the supplier of the implementation. The following common
notations, defined in ISO/IEC 9646-7 [3], are used for the support column:
Y or y supported by the implementation
N or n not supported by the implementation
N/A, n/a or - no answer required (allowed only if the status is n/a, directly or after evaluation
of a conditional status)
NOTE: As stated in ISO/IEC 9646-7 [3], support for a received PDU requires the ability to
parse all valid parameters of that PDU. Supporting a PDU while having no ability to
parse a valid parameter is non-conformant. Support for a parameter of a PDU implies
that the semantics of that parameter are supported.
If this PICS proforma is completed in order to describe a multiple-profile support in a system, it is
necessary to be able to answer that a capability is supported for one profile and not supported for another.
In that case, the supplier shall enter the unique reference to a conditional expression, preceded by "?"
(e.g. ?3). This expression shall be given in the space for comments provided at the bottom of the table. It
uses predicates defined in the System Conformance Statement (SCS), each of which refers to a single
profile and which takes the value TRUE if and only if that profile is to be used.
EXAMPLE: ?3: IF prof1 THEN Y ELSE N
References to items
For each possible item answer (answer in the support column) within the PICS proforma exists a unique
reference, used, for example, in the conditional expressions. It is defined as the table identifier, followed
by a solidus character "/", followed by the item number in the table.
EXAMPLE: A.5/4 is the reference to the answer of item 4 in table 5 of annex A.
A.1.3 Instructions for completing the PICS
The supplier of the implementation shall complete the PICS proforma in each of the spaces provided. In
particular, an explicit answer shall be entered in each of the support boxes provided, using the notation
described in subclause A.1.2.
If necessary, the supplier may provide additional comments in the space at the bottom of the tables or
separately.
More detailed instructions are given at the beginning of the different subclauses of the PICS 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 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

A.3 Identification of the protocol
This PICS proforma applies to the following standard:
ETS 300 009-1 (1996): "Integrated Services Digital Network (ISDN); Signalling System No.7; Signalling
Connection Control Part (SCCP) (connectionless and connection-oriented class 2) to support international
interconnection; Part 1: Protocol specification [ITU-T Recommendations Q.711 to Q.714 and Q.716
(1993), modified]".
A.4 Global statement of conformance
Does the implementation described in this PICS meet all the mandatory requirements of the referenced
standard?
[ ] Yes
[ ] No
NOTE: Answering "No" to this question indicates non-conformance to the protocol
specification. Non-supported mandatory capabilities are to be identified in the PICS,
with an explanation of why the implementation is non-conforming. Explanations may
be entered at the bottom of each table or be attached to the PICS proforma.
The supplier of the implementation will have fully complied with the requirements for a statement of
conformance by completing the tabulations contained in the following clause.
A.5 Capabilities
This clause contains the core of the PICS proforma for the SCCP protocol specified in ITU-T
Recommendations Q.711 to Q.714 as modified by ETS 300 009-1 [1]. The proforma are presented in the
form of tables.
NOTE: The compatibility capabilities with CCITT Blue Book (1988) and CCITT Red Book
(1984) Recommendations are for further study (ffs).
