EC4725 Advanced Telecommunication Systems Engineering

Studies the engineering of communication transport networks, presenting basic concepts in conventional telephony and traffic engineering such as blockage, availability, dimensioning and survivability. The public switched network (PSTN), mobile switched networks (MSN) and public land mobile networks (PLMN) are discussed. The Signaling System No.7 (SS7) architecture for the PSTN is presented along with a variety of transport technologies including the Synchronous Optical Network (SONET)/ Synchronous Digital Hierarchy (SDH). Dense Wavelength Division Multiplexing (DWDM) is also examined. Voice over IP (VoIP) and its associated signaling protocol, the Session Initiation Protocol (SIP), is examined. Skype is used as a case study. VoIP vulnerabilities are also discussed. Cellular telecommunications standards, including GSM/2G, GPRS, UMTS/3G, LTE/4G and 5G are studied. Security measures for different telecommunications standards are also discussed. Concludes with a discussion of Network Management Systems.
