Telecommunication Systems

Lecturer:

Jaromír Hrad (gar.), Ivan Pravda

Tutor:

Jaromír Hrad (gar.), Ivan Pravda

Supervisor:

Department of Telecommunications Engineering

Synopsis:

The subject discusses principles of the telecommunication systems - both digital transmission systems and digital switching systems. The subject will allow students to obtain the overview in the entire telecommunication domain, so that they will be able to solve partial problems related to network traffic. Furthermore, students will also obtain knowledge in VoIP technology, QoS and signaling systems that are used in modern wired and wireless networks.

Requirements:

In order to obtain the credits, students have to meet the following conditions:

1) Be successful in the test.

2) Succesfully deliver 1 assigned report.

3) Participate in all practical exercises.

The examination is based on a test and possible subsequent discussion.

Syllabus of lectures:

1. Telephone channel, voice signal processing, Frame E1.

2. Backbone transmission systems and networks.

3. PDH, SDH, OTH transmission systems.

4. Architecture of digital switching systems, subscribers lines, ISDN. 5. Switching networks type S and T, signaling. 6. Synchronisation in networks, distribution of clocks in networks, creation of slips.

7. Next generation network (NGN).

8. Asynchronous Transfer Mode (ATM), TCP/IP networks.

9. Technology VoIP. Session Initiation Protocol (SIP). Quality of service (QoS).

10. Generation of mobile networks.

11. Basic principles of communication and signaling in mobile networks.

12. Access networks, types and features.
