1. An optical signal level adjustment method comprisingobtaining a fault pattern representing optical signal connection or optical signal disconnection at each wavelength block of each input of each terminal station device;

  • obtaining one or more combinations corresponding to the fault pattern, each of said combinations representing a place where adjustment of transmission dummy light is required, and including a wavelength block, and a terminal station device as items for identifying the place;

    obtaining a dummy light adjustment amount for each of said combinations, said dummy light adjustment amount corresponding to the fault pattern; and

    transmitting, to the terminal station device, which is included in each of said combinations, a control signal for adjusting the intensity of the dummy light in the wavelength block, which is included in each of said combinations, at an output by the dummy light adjustment amount for each of said combinations.
