A method and related system dynamically determines the location of a network outage in a telecommunications network. A plurality of alarm generating network equipments are located at spaced sites along the network. Alarms are generated upon the detection of problems with a signal passing through continuous signal trunks connected between the alarm generating network equipments. The alarm data from the alarm generating network equipments is connected at a single point. Network topology data is stored in a database, defining the relative locations of the alarm generating network equipments in the network and their respectively connected trunks. The alarmed equipment ports are correlated with respective connected alarmed trunks from data obtained in the database as well as collected alarm data. The alarmed trunks are analyzed for identifying the corresponding minimum number of alarm generating network equipments that exist between the alarmed trunks thereby defining effected inter-equipment trunks. The alarmed trunks passing through a particular inter-equipment trunk are analyzed. The analysis then establishes a minimum common span of all alarmed trunks that pass through the inter-equipment trunk, and along which the outage occurs.
