Testing Technologies SIP test environment used for IMS testing

Berlin, June 2005 - Testing Technologies announces today that it will take the lead in developing testing solutions for the emerging standardization of IP Multimedia
Subsystem (IMS) in cooperation with Fraunhofer FOKUS. Testing Technologies SIP test
environment can be used to create new test cases for IMS based testing.

IMS defines a generic architecture for offering Voice over IP (VoIP) and multimedia
services. IMS-based services enable person-to-person and person-to-content
communications in a variety of modes - including voice, text, pictures and video, or any combination of these - in a highly personalized and controlled way.

Due to the different standards and technologies being used when deploying IMS
software and services the testing of services like IMS is too complex for traditional
hardware based testing platforms. Manufacturers and carriers alike have realized the
ease in applying and adopting already existing TTCN-3 based conformance testing
solutions like SIP and UMTS to emerging technologies like IMS.

Manufacturers already working with tools from Testing Technologies are ie. Alcatel and
Motorola, even carriers and others getting there networks and backbone ready and
tested for the rapid deployment of IMS.

IMS testing is yet another proof of concept for the flexibility of TTCN-3, a standard for next generation testing, that is the base of Testing Technologies success in testing devices and applications in markets as diverse as automotive, telecoms and datacoms.
" The rapid test development and deployment allow our clients to stay on the cutting
edge of technology without being forced to continuously invest in new proprietary
hardware based testing platforms" says Testing Technologies CEO Theofanis Vassiliou-
Gioles.

The software based SIP testing environment from Testing Technolgies is a validated and customer proven functional test suite containing 534 test cases for SIP. It comes in two packages, TTsuite-SIP Executable to execute the test cases and analyze the test result and TTsuite-SIP Developers in which the SIP ATS sources can be modified for IMS purposes in the standardized test language TTCN-3. After modification new added or changed test cases can be compiled and executed on the fly.
