Specific course objectives

Understanding of the basic concepts of telecom networks. Ability to understand the reasons behing the selection of specific techniques given the type of services, transmission media and network topology.

Course programme

Structure of a network
Source, signaling, transport, switching. Protocols and interfaces, services characteristics. Circuit and packet switching.

Characterization of transmission media and techniques
General description of the properties of radio, cables and fibers. Effects on transmission. Analog and digital transmission techniques and sources: line codes, A/D conversion, modulation. Advantages of digital communications, introduction to error control.

Basic concepts of traffic theory
Markov systems,, birth-death processes Offered traffic and throughput, Little’s result, Kendall’s notation, samples of M/M/*/*/* systems, Erlang formula and tables.

Multiplexing and transport
FDMA. TDMA: frame, alignement, justification. Spread spectrum: CDMA, Frequency hopping. Examples: FDM telephone mux, PDH hierarchy. SDH. Distributed access: Aloha, CSMA, token

Data networks
Datagram and virtual circuit. The OSI model. HDLC

Switching, signaling and routing
Blocking, non-blocking and rearrangeable networks. Space and time switching. Multistage networks. Signalling: in-band vs. out-band, associated vs. common channel, CCSS7. Routing: definition and propeties, Djikstra and Bellman-Ford algorithms

Samples of systems
Modems; ADSL; local area networks; ATM; TCP/IP; cellular networks. Description will be limited to outline how general concepts are actually implemented.
