Switching of bistable solitons in a recently proposed doubly and inhomogeneously doped fiber system [Phys. Rev. E 58, 5021 (1998)] is studied numerically. It is shown that both upswitching and downswitching of solitons between bistable states are realizable in the given model if the amplification of the input soliton for upswitching and the extraction of energy from it for downswitching are suitably adjusted.
