Annex A (normative): PICS proforma for ETS 300 012-1
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 Purpose and structure
The purpose of this PICS proforma is to provide a mechanism whereby a supplier of an implementation
defined in ETS 300 012-1 [1] may provide information about the implementation in a standardized
manner.
The PICS proforma is subdivided into subclauses for the following categories of information:
- instructions for completing the PICS proforma;
- identification of the implementation;
- identification of the reference ETS;
- PICS proforma tables:
- global statement of conformance;
- tables.
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 [8].
The reference column contained in the tables gives reference to the appropriate part(s) of
ETS 300 012-1 [1] describing the particular item.
NOTE: However, a reference merely indicates the place the core of a description of an item
can be found. Any additional information contained in ETS 300 012-1 [1] has to be
taken into account when making a statement about the conformance of that particular
item.
The following common notations, defined in ISO/IEC 9646-7 [8], are used for the status column:
m mandatory.
o optional.
n/a not applicable - in a given context, it is impossible to use the capability.
o.i qualified optional - for mutually exclusive or selectable options from a set. "i" is the integer which
identifies a unique group of related optional items and the logic of their selection which is defined
immediately following the table, in "Optional Status Notes" area.
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.
x prohibited (excluded) - there is a requirement not to use this capability in the given context.
The following common notations, defined in ISO/IEC 9646-7 [8], are used for the support column:
y for supported/implemented.
n for not supported/not implemented.
x prohibited (excluded) - there is a requirement not to use this capability in the given context.

ETS 300 012-3: October 1998
A.2 Table/item identification
The PICS table is provided with a table/item identification label pre-printed to the left in the table headers.
The labels are composed as follows:
- one capital letter, being the first letter of the layer name;
- a serial number.
Each item in a PICS table is provided with a serial number in the left-hand table column, called "Item No."
To identify an item unambiguously, the table label and the item number are combined by use of a slash
character, "/", e.g. in the 2nd table of the physical layer PICS, the 3rd item is identified by "A.2/3".
A.3 Filling in guidance
The filling in is done in the rows of the right table column named "Support" as follows:
- for implemented items a Y, y, Yes, yes or YES is entered;
- for not implemented items a N, n, No, no or NO is entered.
For each not implemented mandatory item, the client shall give a justification e.g. as an added note
associated with the item.
A.4 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 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.

A.5 Identification of the protocol
This PICS proforma applies to the following standard:
ETS 300 012-1 (1998): "Integrated Services Digital Network (ISDN); Basic User Network Interface (UNI);
Part 1: Layer 1 specification".
A.6 PICS proforma tables
An explicit answer shall be entered, in each of the supported column boxes provided, using the notation
described in subclause A.1.2.
A.6.1 Global statement of conformance
Are all mandatory capabilities implemented? (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
