Learning objectives:
  Giving a comprehensive overview of all most important parts of the telecommunication network,which is here comprehended as a tool for transmitting information to a required recipient in required quality. It concerns terminal equipment, access network solutions, means of traffic contentration, integration of services, multiple utilization of transmission media, effective utilization of these tools, shortening of idle times, optimal solution of transport network configuration.
  Methods of connecting network terminals (telephone sets, fax machines, computers, etc.) by fixed and mobile access networks to terminal switching nodes of transport network. Digital telephone exchanges as part of access or transport networks. Multiple utilization of transport paths. Digital transmission systems. Frame E1. Plesiochronous digital hierarchy. Introduction to Synchronous digital hierarchy.
Knowledge and skills required for the course:
  Basic knowledge from electrical and electronic engineering, and electrical signal transmission .
Learning outcomes and competencies:
  Complex overview with all the related aspects of solving access and transport networks and their devices, especially with reference to prospective solutions of integrating networks and services. Network viewed as the largest cybernetic machine in the world and controlled from the terminal equipment. Processes of this control, as well as its organization, make it possible to get to the roots of control. Applying this knowledge, especially of control organization, also to other areas of economic and social life.
