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.

Learning outcomes of the course unit

Graduate of this subject is able to:
- explain specificity of Fast Ethernet, Gigabit Ethernet, 10 Gigabit Ethernet, 40 Gigabit Ethernet and 100 Gigabit Ethernet,
- demonstrate bases of Asynchronous Transfer Mode ATM,
- reproduce ITU-T SDH Recommendation,
- appraise multiplex SDH structure,
- interpret integration of contributory signals to SDH,
- demonstrate the architecture of the Czech Republic synchronization network,
- demonstrate bases of a Telecommunication Management Network TMN,
- characterize voice transmission using VoIP,
- practice signalling VoIP protocols and covered set H.323,
- operate IP-MPLS routing,
- name important transmission protocols,
- explore VoIP and QoS,
- discuss analogue and digital voice ports
- utilize plan of dialling,
- experiment with high-speed CISCO system,
- demonstrate operational system IOS.


Suitable, but not necessary skills are: - explain basic terms of digital transmission of information, - describe most important parts of converged network, - explain structure of frame and multiframe E1 by G.703 Recommendation, - interpret basis of digital hierarchy, - define Ethernet principle. There is no subject, whose graduation should be necessary requirement for registration of this one.
