Abstract

Hrvatske željeznice izgradile su vlastiti sustav za međusobno komuniciranje svojih djelatnika. U specijalističkoj radnji opisan je sustav željezničkih automatskih centrala, s pripadajućim udaljenim priključcima na području regije Jug. S obzirom kako su iste dosegnule kraj životnog ciklusa tj. nije moguća daljnja dobava opreme i dodatnih licenci, predložena je migracija na modernizirani komunikacijski sustav koji omogućava prelazak na IP rješenja.
Interkonekcija centrala i udaljenih priključaka realizirana je transportnom SDH mrežom. Dan je uvid u postojeću SDH okosnicu te prijedlog modernizacije MPLS tehnologijom.
U budućnosti, odabir komutacije telefonskog prometa i vrste ugrađenih uređaja po kolodvorima, ovisit će o prioritetu sigurnosti telekomunikacijskog prometa u odnosu na troškove održavanja.

Abstract (english)

Croatian Railways has built its own system for communication between its employees. This graduate thesis describes a system of railway automatic telephone exchanges with associated remote units in the South Region. Since they reached the phase-out; i.e. the further procurement of equipment and additional licenses is not possible, migration to a modernized communication system that allows the transition to IP solutions is suggested.
Interconnection between the exchanges and their remote units is realized by transport SDH network. This thesis describes the existing SDH backbone network and proposes its modernization with MPLS technology.
In future, the selection of switching equipment and associated devices deployed at train stations will depend on the priority of telecommunications traffic safety over maintenance costs.
