  It is shown that the nontrivial energy dependencies of $D\bar{D}$,
$D\bar{D}^{*}$, and $D^{*}\bar{D}^{*}$ pair production cross sections in
$e^{+}e^{- }$ annihilation are well described within the approach based on
account for the final-state interaction of produced particles. This statement
is valid for production of charged and neutral particles. Interaction of
$D^{(*)}$ and $\bar{D}^{(*)}$ is taken into account using the effective
potential method. Its applicability is based on the fact that for
near-threshold resonance the characteristic width of peak in the wave function
is much larger than the interaction radius. The transition amplitudes between
all three channels play an important role in the description of cross sections.
These transitions are possible since all channels have the same quantum numbers
$J^{PC}=1^{--}$.
