The possibilities of SS7 signalling transport over IP network using YATE switch
Al-Anqari, Mhannad ; Novotný, Vít (referee) ; Šilhavý, Pavel (advisor)
This study examines the use of SS7 signaling system over IP networks by using the open source PBX YATE. At first it starts with describing the SS7 followed by an explanation of the function of each of its levels and the messages that are used within the SS7 network. The study then sheds some light on the ways of using SS7 inside IP network with the use of some protocols. It also discusses the architecture of YATE and its files, and how it is installed in Linux operating system. Finally, it describes the important files for delivering this task. The study was commenced by using two virtual machines that have two different open source PBX's which are YATE and Asterisk, and after acquiring some results by establishing communication between them via the means of SIP trunk, furthermore the study was extended to the laboratory in order to test it over real servers that have TDM cards, in order to apply the study by the means of SS7 protocols, SIGTRAN, MGCP gateway and SIP-T. The experiments have almost delivered successful communications after conducting a configuration for the files on multiple sides.

Návrh optimalizace daňového zatížení příjmů studentů České a Slovenské republiky
Tkáčová, Janka
The bachelor thesis deals with tax burden optimization of incomes Czech and Slovak students. In the theoretical part, the basic terminology of tax system and labour law is described. These terms are consequently used for calculation of tax burden optimization of students. Model examples of students incomes have been formed on the basis of a questionnaire, which is analysed at the beginning of the practical part of the thesis. The goal of the thesis is to propose the best possible option for optimization of tax burden for students.
