Course detail

High-speed Communications Systems

FEKT-CVKSAcad. year: 2017/2018

The subject deals for applicants of deeper knowledge of Synchronous Digital Hierarchy SDH, basics of Asynchronous Transfer Mode ATM and first of all of modern technology Ethernet, Fast Ethernet, Gigabit Ethernet, 10 Gbit Ethernet, 40 Gbit Ethernet, 100 Gbit Ethernet and Frame Relay. Students are also instruct about Telecommunication Management Network TMN. Students obtain practical experiences with CISCO 2821 system, stress is given to IP telephony in CISCO networks and to IP-MPLS routing. Students expressively deepen knowledge of signalling protocols VoIP, covered protocol set H.323 and Quality of Service QoS in VoIP relevance.
