Course Description

Signalling System No.7 is commonly known as SS7 and sometimes referred to as C7. SS7/C7 is a system used to implement signalling and protocols for telecommunications networks. SS7 supports both fixed-line and cellular networks. This course covers in-depth analysis of SS7 signalling, architecture, services, and performance monitoring issues and tools

Course Objectives

  • Overviewing public switched telephone networks (PSTNs)
  • Exploring signalling systems, associated terminology and concepts
  • Explaining the C7/SS7 protocol stack for both cellular and fixed line systems
  • Planning the integration and testing of new SS7 applications
  • Assisting in the design of new mobile network applications and services
  • Explaining how to navigate C7/SS7 standards
  • Explaining how to analyse the C7/SS7 protocols
  • Understanding and navigate service protocol standards (INAP, CAMEL and MAP)

Who Should Attend?

  • Telecommunication engineers
  • Technical development and support professionals involved in the support and implementation of networks and services
  • Those professionals involved in the design and implementation of next-generation telecommunication solutions
