Successful Implementation of Telelogic Tau in IN Development at Lucent

Successful Implementation of Telelogic Tau in Intelligent Network Development at Lucent Technologies MALMÖ, Sweden, June 13, 2000 - Telelogic AB (Stockholm Stock Exchange: TLOG), a leading supplier of software development solutions for the real- time communications industry, announced that the Advanced Software Construction Center (ASCC) of Lucent Technologies recently selected Telelogic's state-of-the-art Telelogic Tau SDL and TTCN Suites to be utilized in the development process of their Intelligent Network (IN) services. The ASCC initiated implementation of Telelogic Tau's SDL and TTCN Suites during quarter one, and are planning to deploy the tools during the year. Telelogic Tau provides an integrated solution that allows systems engineers to create graphical, platform-independent Message Sequence Chart (MSC) requirements and SDL reference models. Utilizing SDL's formal syntax, Telelogic Tau will allow Lucent's ASCC engineers to prototype the real-time behavior of an IN service at a very early phase of the development cycle through simulation and validation. In addition, Telelogic Tau will automate the IN feature testing process by taking advantage of Telelogic Tau's automatic TTCN test-case generation feature. "We found Telelogic Tau to be the only tool suite to offer a single, integrated solution to speed-up our IN service development and testing process," said Mark Atwater, director of Lucent Technologies, ASCC. "The capabilities for automatic test suite generation and test coverage reports are the most important aspects of this tool for our development process," said Swapna Gangopadhyay, technical manager of Lucent Technologies, ASCC. "Telelogic is delighted that the process stability and efficiencies Lucent's ASCC has gained from using Telelogic Tau in Europe, is now being deployed at Lucent sites in the U.S. We are pleased to add Lucent's ASCC to our growing list of U.S. customers," commented Lawrence Moss, Telelogic global account manger for Lucent.
