Foreword
This Interim European Telecommunication Standard (I-ETS) has been produced by the Terminal
Equipment (TE) Technical Committee and approved by Multimedia Terminals and Applications (MTA)
Project of the European Telecommunications Standards Institute (ETSI).
An ETSI standard may be given I-ETS status either because it is regarded as a provisional solution ahead
of a more advanced standard, or because it is immature and requires a "trial period". The life of an I-ETS
is limited to three years after which it can be converted into an ETS, have its life extended for a further two
years, be replaced by a new version, or be withdrawn.
This I-ETS is part 3 of a multipart standard covering "Integrated Services Digital Network (ISDN);
audiovisual services in-band signalling testing" as described below:
Part 1: "Test Suite Structure and Test Purpose (TSS&TP)";
Part 2: "Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing
(PIXIT) proforma";
Part 3: "Protocol Implementation Conformance Statement (PICS) proforma specification".
Proposed announcement date
Date of adoption: 24 October 1997
Date of latest announcement of this I-ETS (doa): 28 February 1998

1 Scope
This Interim European Telecommunication Standard (I-ETS) is part 3 of a three part I-ETS dealing with
conformance testing of Integrated Services Digital Network (ISDN) Videotelephony terminals. Part 1
contains the Test Suite Structure and Test Purposes (TSS&TP) while part 2 contains the Abstract Test
Suite (ATS) in Tree and Tabular Combined Notation (TTCN) and the partial Protocol Implementation
eXtra Information for Testing (PIXIT) proforma. Part 3 provides the Protocol Implementation Conformance
Statement (PICS) proforma for the inband signalling aspects of an ISDN Videotelephony terminal which
uses one or two B channels, and which implements the frame structure and associated syntax as
specified in ETS 300 144 [2] and the inband signalling procedures as specified in ETS 300 143 [1], in
accordance with the relevant guidance given in ISO/IEC 9646-7 [6].
The supplier of an implementation of a Videophone that is claimed to conform to ETS 300 143 [1] and
ETS 300 144 [2] is required to complete a copy of the I-ETS Protocol ICS proforma provided in annex A.

capability set, cap set: A sequence of capability codes started by the capability marker code.
ECS channel: Optional 800 kbit/s channel for use in encryption.
ICS proforma: A document, in the form of a questionnaire, which when completed for an implementation
or system becomes an ICS.
initial channel: The first channel established in a videophone call.
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, information object ICS, etc.
mode 0F: Transmission mode in which the initial channel contains framing, and 7-bit
CCITT Recommendation G.711 [7] audio signal is being transmitted.
mode 0U: Transmission mode in which the initial channel does not contain framing, and 8-bit
CCITT Recommendation G.711 [7] audio is being transmitted.
Multipoint Command Visualization-Forcing (MCV): Transmitted by a terminal to force an associated
MCU to broadcast its video signal. (Used to transmit the picture of a chairman or VIP, alternatively to hold
a picture source during the transmission of graphics).
Multipoint Indication Visualization (MIV): Transmitted by an MCU to indicate to a terminal that its video
signal is being seen by other terminals (otherwise known as "On-air" indication).
Multipoint Command Conference (MCC): Transmitted by an MCU to a terminal. The terminal receiving
MCC shall make its outgoing transfer rate equal to its incoming transfer rate, and its outgoing audio rate
equal to its incoming audio rate.
Multipoint Command Symmetrical (MCS) data-transmission: Transmitted by an MCU when setting up
data broadcasting. On receipt, a terminal shall prepare itself for data reception and ensure, by mode
change if necessary, that its outgoing data channel occupies the same capacity as its incoming data
channel. A terminal in receipt of MCS cannot initiate data broadcasting
Multipoint Indication Secondary-Status (MIS): Transmitted by an MCU to a terminal for information,
with the meaning that since other terminals of higher capability are participating in the conference-call, this
terminal does not necessarily receive all the signals that are sent to those other terminals (see annex B).

specification.
remote terminal: The terminal with which the IUT is communicating, i.e. the test tool.
Video Indicate Suppressed (VIS): This symbol is used to indicate that the content of the video channel
does not represent a normal camera image. The video encoder may be without video input or an
electronically-generated pattern may have been substituted.
Video Indicate Active (VIA): Complementary to VIS. The video source is the only one, or, in the case that
more video sources are to be distinguished, it is that designated "video No. 1".
VIA2: Equivalent to VIA, but designating "video No. 2" as the source.
VIA3: Equivalent to VIA, but designating "video No. 3" as the source.
Video Indicate Ready-To-Activate (VIR): This symbol is transmitted by a terminal whose user has
decided not to send video unless video from the other end will also be received.

Annex A (normative): PICS proforma for ISDN 1B or 2B Videotelephony in-
band signalling
Notwithstanding the provisions of the copyright clause related to the text of this I-ETS, ETSI grants that
users of this I-ETS may freely reproduce the PICS proforma in this annex so that it can be used for its
intended purpose and may further publish the completed PICS.
A.1 Instructions for completing the PICS proforma
The supplier of the implementation shall complete the PICS proforma in each of the spaces provided.
If necessary, the supplier may provide additional comments separately.
A.1.1 Purposes and structure
The purpose of this PICS proforma is to provide a mechanism whereby a supplier of a terminal
implementing the requirements defined in ETS 300 143 [1] and ETS 300 144 [2] 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 ISDN 1B or 2B Videotelephone;
- ICS proforma tables (containing the global statement of conformance).
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 [6].
Item column
Contains a number which identifies the item in the table.
Item description column
Describes each respective item (e.g. parameters, timers, etc.).
Reference column
Gives reference to ETS 300 143 [1] and ETS 300 144 [2], except where explicitly stated otherwise.
Status column
The following notations, defined in ISO/IEC 9646-7 [6], are used for the status column:
- 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 or may not be supported;
- o.i: qualified optional - for mutually exclusive or selectable options from a set. "i" is an integer which
identifies a 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" 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. For nested conditional expressions, the syntax

---------------------- Page: 13 ----------------------

SIST I-ETS 300 763-3 E1:2003
Page 12
I-ETS 300 763-3: November 1997
"IF . THEN (IF . THEN . ELSE.) ELSE ." shall be used to avoid ambiguities. If an ELSE clause
is omitted, "ELSE n/a" shall be implied.
NOTE: Support of a capability means that the capability is implemented in conformance to
ETS 300 143 [1] and ETS 300 144 [2].
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 [6], are used for the support column:
- Y or y: supported by the implementation;
- N or n: not supported by the implementation;
- N/A or —: no answer required (allowed only if the status is N/A, directly or after evaluation of a
conditional status).
References to items
For each possible item answer (answer in the support column) within the PICS proforma there exists a
unique reference. This is defined as the table identifier, followed by a solidus character "/", followed by the
item number in the table. If there is more than one support column in a table, the columns shall be
discriminated by letters (a, b, etc.), respectively.
EXAMPLE 1: A.5/4 is the reference to the answer of item 4 in table 5 of annex A.
EXAMPLE 2: A.6/3b is the reference to the second answer (i.e. in the second support column)
of item 3 in table 6 of annex A.
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 ICS should be named as the
contact person.
