Course detail

Access and Transport Networks

FEKT-BPC-PTSAcad. year: 2019/2020

The subject deals with the evolution of telecommunication networks and their convergence with computer networks. The stress is placed on modern analysis of access and transport networks while considering their diversity and also concurrent features together with the application of analogue and digital modulations. Primary attention is given to the complex usage of an E1 frame by ITU G.703 recommendation. Students obtain a view of the private and public telephony exchanges, they understand the principles of digital switches, of the current signalling system SS7 and of the SIP internet exchange. Out of print will specificity of measuring in converged networks. Basic attention will devoted to higher order digital systems, to protection of transport networks and to quality evaluation.

Learning outcomes of the course unit

Upon course completion, students will be able to:
- differentiate between the relationship of access and transport networks and their facilities solution,
- apply analogue and digital modulations,
- explain the terms sampling, quantization and coding,
- discuss sampling theorem,
- explain the E1frame,
- express the spectrum of sampling signal,
- measure active network elements,
- set SIP exchange and digital transmission equipment,
- take one's bearings in higher order systems
- evaluate the development of converged networks

Prerequisites

The course is obligatory, students should be able to: - demonstrate the principles of circuit switching, - interpret the principles of packet switching, - enumerate the possibilities of separating communication channels, - express the idea of A/D and D/A conversion, - discuss elemental terms of the signal processing area, - apply the basic principles and protocols of the Ethernet network. Students should have the basic knowledge of communication systems, which they obtained in the obligatory courses in their previous study.
