Access networks can have a large number of subscribers, any failure in the service represents significant loss for the service providers. Therefore, fault surveillance and performance monitoring are important issues to ensure the correct transfer of information to the users, and a real time, non-intrusive fault surveillance system is essential to reduce construction and maintenance costs and improving service reliability. In this line, maintenance involves the whole operations required to set up and maintain, within prescribed limits, any element entering into the setting-up of a connection to guarantee the performances of the optical carrier, and locate any fault in the access network.
