The invention provides an autonomous geo-referenced fault data detection, storage and management system and method for transmission line network such as cable distribution networks, based on an application server architecture, wherein autonomous means automatic and without the need of human intervention. The system comprises a server having a database and a network interface adapted to be linked to a communication network, the network interface for receiving and relaying data to the server, the data comprising at least one of fault data and management data, the fault data comprising at least one of geo-referenced ingress data and geo-referenced egress data and the management data comprising at least one of user data, administrator data and fault status data, the server autonomously updating the database by incorporating the relayed data in the database to provide a stored data.
