Overview

SIST-TS TS 101 340 V1.1.1:2004 outlines the Protocol Implementation Conformance Statement (PICS) proforma for the support of supplementary services in H.323 systems, specifically addressing ITU-T H.450.1. Published by the Slovenian Institute for Standardization (SIST) and aligned with ETSI standards, this technical specification is a key reference for ensuring interoperable telecommunications and IP-based voice solutions using H.450.1-compliant supplementary services.

The PICS proforma enables suppliers to document, in a standardized format, which protocol features and options are implemented. This is essential for validating conformance, facilitating system integration, and supporting procurement and deployment decisions for solutions based on the H.323 multimedia communications standard.

Key Topics

• Protocol Implementation Conformance Statement (PICS):
  The core of the standard is a detailed, structured questionnaire allowing suppliers to report compliance with H.450.1 requirements for supplementary services in H.323 environments.

• Supplementary Services in H.323:
  H.450.1 specifies the generic functional protocol for supplementary services, such as call transfer, call hold, call waiting, and more, within packet-based multimedia communications systems.

• Role Identification:
  Proforma sections for identifying whether the implementation acts as an endpoint, gateway, gatekeeper, MCU, or performs other source/destination entity functions.

• Major and Subsidiary Capabilities:
  Clear breakdown of mandatory and optional protocol procedures, such as APDU transport, sending and receiving APDUs, handling of third-party initiated procedures, and support for multiple simultaneous APDUs.

• Protocol Data Units and Parameters:
  Coverage of specific encoding and transmission requirements for APDUs (Application Protocol Data Units), including ASN.1 encoding, manufacturer-specific information, and support for standard protocol fields.

• Supplier and Implementation Identification:
  Structured fields for uniquely identifying the implementation under test (IUT), system under test (SUT), product supplier, client details, and relevant contact persons.

• Conformance Testing Reference:
  Aligns with ISO/IEC 9646-7, globally recognized guidelines for OSI conformance testing and implementation conformance statements.

---

Applications

• Telecommunications Infrastructure:
  Vital for manufacturers and service providers to demonstrate compliance of their H.323-based IP telephony products and network elements (gateways, terminals, gatekeepers, MCUs) with the mandatory requirements for supplementary services.

• System Integration and Procurement:
  Ensures that telecommunications solutions can be assessed for interoperability, simplifying integration of multi-vendor products within enterprise and carrier IP networks.

• Product Certification and Quality Assurance:
  Used as a benchmark for product testing, certification, and quality assurance processes in VoIP and multimedia communications deployments.

• Support for Supplementary Voice Services:
  Facilitates standardized deployment of enhanced voice features such as call transfer and call hold in converged IP networks, supporting robust business communications.

Foreword
This Technical Specification (TS) has been produced by ETSI Project Telecommunications and Internet Protocol
Harmonization Over Networks (TIPHON).
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 telecommunication specification. Such a statement is called an Implementation
Conformance Statement (ICS).

ITU-T Recommendation H.450.1 [1] in compliance with the relevant requirements and in accordance with the relevant
guidance given in ISO/IEC 9646-7 [5].
The supplier of a protocol implementation which is claimed to conform to ITU-T Recommendation H.450.1 [1] is
required to complete a copy of the PICS proforma provided in annex A of the present document and is required to
provide the information necessary to identify both the supplier and the implementation.

Annex A (normative):
PICS proforma for ITU-T Recommendation H.450.1
Notwithstanding the provisions of the copyright clause related to the text of the present document, ETSI grants that users
of the present document 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 ITU-T Recommendation H.450.1 may provide information about the implementation in a
standardized manner.
The PICS proforma is subdivided into subclauses for the following categories of information:
- guidance for completing the PICS proforma;
- identification of the implementation;
- identification of the protocol;
- global statement of conformance;
-roles;
- major capabilities;
- subsidiary capabilities;
- operations;
- arguments, results and errors;
- timers.
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.
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 (for example parameters, timers, etc.). It
implicitly means "is < item description > supported by the implementation?".
ETSI
8 ETSI TS 101 340 V1.1.1 (1999-09)
Status column
The following notations, defined in ISO/IEC 9646-7, 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 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", "x" or "n/a") depends on the support of
other optional or conditional items. "i" is an integer identifying a unique conditional status
expression which is defined immediately following the table;
i irrelevant (out-of-scope) - capability outside the scope of the reference specification. No answer is
requested from the supplier.
Reference column
The reference column makes reference to ITU-T Recommendation H.450.1, except where explicitly stated otherwise.
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, 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).
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 "?" (for example ?3). This expression shall be given
in the space for comments provided at the bottom of the table. It uses predicates defined in the SCS, each of which refers
to a single profile and which takes the value T
