Supervisor:

Department of Telecommunications Engineering

Synopsis:

The course is oriented to audio or video issues in telecommunication networks, both fixed and mobile. Students will learn principles of switching systems and their management as well as the course will provide them with an overview of signaling systems in central exchanges and networks. The focus is on digital switching systems as circuit as packet switch oriented, i.e. so-called next generation network (NGN) and voice communication in 4G networks. (VoLTE).

Requirements:

General overview of telecommunications and ICT

Syllabus of lectures:

1. Telecommunication network. Switching system. Control system and switching elements. Principle of control of a switching system. Generation switching systems. Softswitch.

2. Numbering plans for telecommunication networks. Number portability and other services in liberalized telecommunications.

3. Signaling in switching systems. Analog systems, CAS and CCS. Overview of analog signaling U, P, K / MFC, E & M and etc.

4. Signaling CCS. Signaling systems, DSS1, Q-sig, DPNSS.

5. Signaling SS7 - part MTP L2 and L3, protocols ISUP, SCCP, TCAP, and INAP.

6. IP telephony, principles, scenarios. Quality of IP services, provision and evaluation.

7. Overview of VoIP protocols. SIP protocol, Part 1.

8. Protocol SIP, Part 2.

9. Intelligent Network (IN). Definition, implementation, trigger points and their specifications.

10. Next generation network (NGN). IMS. Definitions, features, principles, application. Convergence with existing networks.
