Course Objectives

This course gives the participants detailed knowledge of the structure and functions of SIGTRAN that can be used to carry SS7 messages over IP connections. During the course, we will discuss all SIGTRAN protocols, stressing especially SCTP and M3UA, as the first is mandatory for any SIGTRAN system and the second is chosen by major GSM/UMTS equipment vendors to be implemented in their products.



The participants should have basic knowledge of SS7 and IP.


Training Structure

Two-day training divided into logical sessions.



Instructor-led training with trace analysis and exercises based on the provided traces (working with a protocol analyser), presenting both positive and negative scenarios.
