Communications Software Specification and Software Development

Telelogic SDL Suite™ is a real-time, software development solution that provides specification and development capabilities for complex, event-driven communications systems and protocol software.  SDL Suite supports the ITU-T Specification and Description Language (SDL) standard, providing visual design and automatic software generation to increase quality and productivity.

SDL Suite benefits developers by:

  • Ensuring application quality through continuous model checking, co-simulation, and debugging
  • Protecting investments using existing C/C++ legacy code in new protocol designs
  • Understanding application behavior early by simulating design and functionality – without writing a single line of code, even in incomplete and target-independent models

Compliance Testing of Communication Systems Using TTCN-2

Telelogic TTCN Suite™, the de facto standard environment for compliance testing of communicating systems, is used worldwide to test telecommunications and data communications equipment ranging from built-in silicon to huge switches and intelligent network services. TTCN Suite combines with Telelogic SDL Suite to provide a tightly-integrated development and test environment.

TTCN Suite benefits testers by:

  • Improving product quality through seamless design and testing integration
  • Increasing productivity through a versatile, standards-based test definition language that supports manual and automatic test script generation and execution
  • Lowers costs via a modular process whose structure allows creation of reusable libraries across different system versions and hardware platforms

Butler Group – Telelogic Lifecycle Solutions Technology Audit

Telelogic Lifecycle Solutions is a new grouping of the company’s existing portfolio into a suite that embraces most of the application development lifecycle. This lifecycle is an increasingly collaborative function, and the standalone tools of the past need to be better integrated to streamline the application development process, in order to support the rapid and accurate development of applications that genuinely support the organizations they are deployed in. Read the full Butler Group Technology Audit and find out why they name Telelogic as a leader in advancing ALM tools.

White Paper: Bluetooth Development with SDL and TTCN-2

The Bluetooth Specification was issued by the Bluetooth Special Interest Group (SIG) in August, 1999. As originally released, the specification is quite complex, spanning over 1068 pages. Since then, as the standard has evolved, it has grown considerably. Many devices employing Bluetooth are aimed at the consumer, which means that device developers must work quickly to get their products to market – usually within months. This document describes how a development project can benefit from the graphical real-time design language SDL (Specification and Description Language) and the testing language TTCN-2.

On-Demand Webcast: Developing Next Generation Protocol Stacks: Beyond 3G

New Generation protocols such as 802.16 (WiMAX), IPv6, and many more, benefit greatly from Model Driven Development (MDD); all the underlying protocols can not only be specified and designed, they can also be iteratively implemented and executed throughout the development process. Test cases can be designed and run against this model. This ability to simulate and test in both the development environment and on the target device itself results in unparalleled productivity. Telelogic will demonstrate how this is accomplished using the industry’s de facto standards in protocol stack development and testing, SDL Suite and TTCN Suite. In this on-demand Webcast, we will describe some of the issues software developers face when developing next generation protocol software and how MDD can assist the development process.

Case Study: Taking off with TTCN

The world of aviation communications is changing quickly. With Telelogic's help, ARINC - the leading supplier of communications for the aerospace sector - is ensuring that as new aviation communications products are created, there is a testing capability that will be able to evolve with them.

Case Study: Automated Testing Saves Ericsson Valuable Time

Testing became especially important when Ericsson wanted to automate their process to deliver high quality applications to their customers.

Case Study: A Faster “Last Mile” – Using SDL to Develop ADSL Products

Siemens successfully used the Telelogic TAU SDL Suite to develop their new ADSL product, XpressLink. Valued features were the possibility to simulate and the automatic code generation, which both accelerated the development process. SDL is the “ideal description language for telecommunications use,” concludes the project manager.

Case Study: Telcordia Technologies Develops Commercial SDL-Model of IP-Telephony Standard

At Telcordia Technologies (formerly Bellcore) in New Jersey, a project group in the research department has created an SDL model of the latest IP telephony standard MGCP (Media Gateway Control Protocol). Originally used as a blueprint in a consulting project, the model has now been converted into a product and is commercially available from Telcordia Technologies.
