The work is devoted to the research of the electrical parameters of the domestic telephone cables in the frequency range from 1 to 30 MHz. The paper presents the results of the experimental determination of the frequency characteristics of the transmission parameters and the crosstalk of the TPPep 10х2х0,4 and TPPepZ 10х2х0,4 types telephone cables produced by ODESKABEL PJSC. The conformity of the domestic production cables with the requirements for digital subscriber line cables for VDSL2 technology services is determined. According to the results of the measurements, approximation formulas for the frequency dependence of the own attenuation, near end crosstalk and equal level far end crosstalk, which are proposed to be used in the modelling of the transmission systems using VDSL2 technology on the domestic broadband access networks based on these cables, are determined.
