SS7 and SIGTRAN Workshop
Course Overview
The Signaling System No.7, widely known as SS7, provides the foundation for signaling procedures in Telecommunication Networks. Originally developed to manage voice calls in fixed-line telephone networks it rapidly expanded into supporting service add-on’s, such as Call Hold, Call Waiting, Number Presentation services and many more.
Soon, Mobile Networks adopted SS7 not only for its versatility and modular design, but also to provide full compatibility with fixed-line network services.
Entering into the era of IP networks required the transport of SS7 signaling messages over IP networks. Signaling Transport (Sigtran) addresses this transition by providing new concepts, functions and adaptation.
Target Audience
Telecommunication and Mobile Operators technical staff, support engineers, software developers and professionals who are interested in signaling procedures and application.
This course will also benefit those in the wider technical community who are required to understand SS7 / Sigtran protocols, their features and capabilities.

Course Objectives
This training will provide participants with a strong foundation in both SS7 and Sigtran.
- Starting with signaling principles, we will take a closer look at the foundation of modern signaling systems and their functional definition with the help of the OSI model.
- Participants will learn the functions and architecture of each protocol.
- With the help of the relevant ITU-T technical specification papers, participants will apply the knowledge for a basic protocol analysis, using signaling procedure samples collected from live networks.
- A variety of examples and message samples will be illustrated to drive home important concepts and enhance the training experience.
