Abstract: An information processing system which performs a device initial setting customization method includes a CPU, a monitoring control unit, an object initial setting table, and a database of instance data. When a device is newly mounted on a predetermined slot of a shelf, the monitoring control unit newly generates instance data by referring to the object initial setting table and store the instance data in the database. When the new instance data is required to be corrected for each object, the monitoring control unit corrects the new instance data using object initial setting correction data. When the new instance data is required to be corrected for each instance, the monitoring control unit corrects the new instance data using instance initial setting correction data.

Abstract: An optical transmission device according to the present invention comprises: a Raman amplification means; a main signal light sending means which sends first main signal light; a communication interruption detection light monitoring means which sends a first signal if it cannot detect communication interruption detection light; a main signal light monitoring means which sends a second signal if it cannot detect second main signal light; a light monitoring signal analysis means which sends a result of its analysis of a light monitoring signal as a third signal in a predetermined period of time; and a control means which makes the Raman amplification means suspend the generation of the excitation light, if it cannot receive the third signal even after the elapse of the predetermined period of time in the state it has received the first signal and has not received the second signal, and stops sending of the first main signal light from the main signal light sending means when receiving the second signal further.
