INTRODUCTION
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
PROGRAM 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
