Course detail

Access and Transport Networks

FEKT-BPC-PTSAcad. year: 2025/2026

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.

- 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.

Rules for evaluation and completion of the course

0-15 points for activity in laboratories.
0-15 points for a laboratory test,
0-70 points written exam with the support of e-learning, compulsory part for passing the course, optionally oral exam with written preparation.
The exam is focused on verifying the orientation in the issues of access and transport networks. 
Attendance at laboratories and individual project are compulsory, justified absence from laboratory exercises can be made up after prior arrangement with the instructor.

Aims

Giving a comprehensive overview of all most important parts of the converged network, which is here comprehended as a tool for transmitting information to a required recipient in required quality. Access network solutions, means of traffic concentration, integration of services, multiple utilization of transmission media. Principles of the computer network in relation to the classical telecommunication network.
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
