Abstract

Uz različite DSL−tehnologije ostvaruju se određene prijenosne brzine na korisničkim linijama u pristupnim mrežama. U pravilu, što su postignute prijenosne brzine veće to je domet DSL−tehnologije u pristupnoj mreži kraći iz razloga preslušavanja u zajedničkim linijama u kabelu. Svako povećanje broja DSL sustava u paričnoj pristupnoj mreži uzrokuje dodatno smanjenje postignutih prijenosnih brzina. Tema ovog rada je analiza paričnih pristupnih mreža s gledišta raznih usluga i ograničenosti parične pristupne mreže po kriterijima korištene DSL−tehnologije, penetracije DSL sustava i preslušavanja u kabelu. U radu je detaljno analiziran i simuliran VDSL2, zadnja inačica DSL−tehnologije, njezine mogućnosti i implementacija u postojeće DSL okruženje u pristupnim mrežama, te je dana predikcija vrste usluga i postotka korisnika kojim bi te usluge bile dostupne. Rezultati simulacija izrađeni su pomoću softvera koji je nastao na temelju rezultata mjerenja na kabelima u produkciji, te su prikazani u obliku krivulja i analizirani.

Abstract (english)

With a variety of DSL technologies certain transmission rates are achieved on subscriber lines in access networks. In general, the higher transmission rates are, the shorter is the range of DSL technology in access network due to crosstalk on shared lines in the cable. Any increase in the number of DSL systems in pair access network leads to an additional decrease in achieved transmission rates. The theme of this thesis is to analyze pair access networks in terms of various services and limited pair access network according to the criteria used in DSL technology, DSL system penetration, and cable crosstalk. This thesis examines and simulates in detail VDSL2, the last version of DSL technology, its features and implementation in the existing DSL environment in access networks, and gives predictions of types of services and the percentage of users whom these services would be available. The results of simulations were made by using software that was created based on the results of measurements on cables in the production and are presented in the form of curves and analyzed as well.
