Berlin/Sophia Antipolis, February 2002 - Worldwide leading
companies of the telecommunication industry used for one week
at the IMTC (International Multimedia Telecommunications Consortium)
/ ETSI / TTC (Telecommunications Technology Committee ) Winter
Interoperability event in December 2001 in Kobe, Japan the
opportunity to test their products for the Internet and UMTS
signalling protocol SIP thoroughly against each others products
and against testing tools based upon the new test standard
TTCN-3.
The main focus of the event was to check interoperability
between H.323 or SIP implementations. The Japanese Standard
Organisation TTC successfully hosted for the first time such
a technical meeting regularly called by IMTC or the ETSI Plugtests
Service. ETSI, active in Voice and Multimedia over IP standardisation
works in particular through its committee EP TIPHON (ETSI Project
Telecommunications and Internet Protocol Harmonization Over
Networks). It provided some early results of its activities,
in particular through the active participation of experts,
able to execute, with a new, advanced test platform, several
conformance test cases for SIP drafted by ETSI EP TIPHON. Experts
from the ETSI PTCC (Protocol and Testing Competence Centre)
and Testing Technologies IST GmbH, Berlin provided participants
with the opportunity to make use of a conformance testing service
for SIP Proxies and User Agents. This service was based on
an initial set of test cases taken from the ETSI TIPHON SIP
test suite, which contains over 400 test purposes and detailed
tests written in the standardised testing language TTCN-3 (Testing
and Test Control Notation).
"The test event in Kobe was a big success for all participants" summarized
Mr. Philippe Cousin, manager of the ETSI Plugtests service.
In contrast to in-house single tests, test events such as these
offer companies the possibility to test their products under
realistic and practical conditions for the interoperation with
products of other vendors. SIP products could be analysed by
systematic functional tests using the SIP test tool by Testing
Technologies based on ETSI test suites. Many manufacturers
of ICT equipment are realising that including the possibility
of conformance testing at interoperability events gives real
added value to the entire process of validating products and
standards. Using TTCN-3 for the tests made them well defined,
comparable and repeatable. Mr. Wiles, manager of the PTCC said "The
newly adopted test standard TTCN-3 could demonstrate its potential.
Furthermore, for ETSI as a standards organization, it is very
important that big players in the market test their products
together in order to gain interoperability and making things
work - and by doing so to use TTCN-3 as a basis for rigorous
testing."
"The test event in Kobe showed the participants: the
use of TTCN-3 results in objective test results, which clearly
indicated conformance or non conformance of products. The test
results have been a basis to modify the products in order to
gain higher-quality, stable and robust SIP products for the
telecommunication market". Theofanis Vassiliou-Gioles,
CEO of Testing Technologies IST GmbH and active participant
in the test event takes even one step further: Questions and
ambiguities, even minor disagreements resulting from interoperability
tests between two products can be resolved by our independent,
standard-based testing tool."
The test event in Kobe was a further break-through for the
test standard TTCN-3. ETSI and Testing Technologies plan to
extend the SIP tests and to develop further tests for other
protocols, e.g. for OSP from the E-Business sector, in order
to penetrate TTCN-3 as a test standard into all segments of
the telecommunication and information technology market.
