The dielectric response of gallium doped Cd_{0.99}Mn_{0.01}Te and CdTe alloys possessing DX centers was studied by impedance spectroscopy. Complex modulus and impedance spectroscopic plots were analyzed. Near ideal Debye response of CdTe:Ga was observed, whereas for Cd_{0.99}Mn_{0.01}Te:Ga samples non-Debye behavior was stated. Different relaxation responses may be related to various local atomic configurations in the vicinity of the DX centers in the studied materials.
