Methodology for the identification of latent problems on functioning equipment

The conversion equipment acquired by Telecom Italia is the object of a series of controls and checks carried out to maintain unaltered in time the quality of the services furnished. The reports of the maintenance activities constitute a valuable part of the data whose examination allows the opportune identification of the latent critical difficulties of the equipment. Next to this "traditional method", Telecom Italia has elaborated, together with manufacturers, a methodology which allows the identification of latent critical difficulties before they may present themselves in the form of breakdown. As a kind of example, a real case of system check-up, undertaken by the provider Installazioni Impianti is discussed.
