A.c. conductivity $σ $($ω $) and dielectric parameters ($ε $ and tg $δ $) of Ge-As(Sb)-S-I system glasses are investigated in the frequency range of 10$^{4}$-10$^{10}$ Hz and temperature interval from room to glassforming $T_{g}$. Combined hopping mechanism of bipolarons and single-polaron charge transfer defined the temperature and frequency dependences of $σ $($ω $). Dielectric properties of glasses are explained on the basis of model charge defects.
