Abstract:<br />
The course in switching technologies focuses on the nature of commutations, their practical models, their<br />
measurements and simulations. The field of study is digital switching, processor management and common<br />
channels for signals.<br />
Course content:<br />
The course contains topics on the application of switching technologies in telecommunications. The<br />
Commutation course covers the use of tools and basic knowledge to provide reliable telecommunication.<br />
Teaching and assessment:<br />
Lectures clarify the theoretic aspects of the topics and provide a sufficient number of examples. This enables the<br />
students to prepare in advance for the practice sessions and to work independently during the classes.<br />
Workshops are held in computer labs. Students do practical work based on developing, testing and debugging<br />
computer networks.<br />

Abstract:<br />
The aim of the subject is to provide students with basic knowledge in the area of cable engineering: terminology,<br />
classifications, parameters, methods, elements, technical solutions, protection, contents of projects, mounting and<br />
exploitation documentation, measures and calibrations.<br />
Course content:<br />
Main principles in communications cable engineering. Classification systems. Construction of communication<br />
cables. Insulation and twisting of conductors of symmetrical cables. Formation of cabling sheaves. Symmetrical<br />
cables. Construction, area of application, choice. Construction and characteristics of coaxial cables. Homogeneity<br />
lines. Model, definitions, primary and secondary parameters. Calculation of secondary parameters of homogeneity<br />
lines. Working parameters of homogeneity lines. Bending of signals transmitted on homogeneity lines. Shielding of<br />
symmetrical cables. Active resistance and inductivity of transmission lines. Capacitance and conductivity of<br />
transmission lines. Electromagnetic processes in coaxial cables. Mutual influences between communication lines.<br />
Essence and primary parameters. Secondary parameters on mutuality influences between communication lines.<br />
Symmetried cable lines. Essence, methods for symmetring on cable symmetric lines. Protection of cable lines<br />
from breaking influences. Earth protection and equalization installations. Design of cities communication cable<br />
networks. Communication management in buildings. Design of structural cable installations. Repair and<br />
maintenance of communications cable lines.<br />
Teaching and assessment:<br />
The lectures are carried out according to a preliminary timetable and supported by visual aids. Company<br />
information and materials are given to the students. During the practice sessions discussions with the students<br />
and periodical checking of their knowledge is carried out. Every student has to develop a course paper by himself<br />
or herself and present it by the end of the term. Students can ask questions concerning lecture material, practice<br />
sessions and course paper during consultation hours.<br />
