ABSTRACT:
A method and apparatus for detecting traffic-affecting failures in a telecommunications network; by inferring the most probable location of each such failure, given multiple alarm indicators along a network circuit; correlating circuit alarms to trunk failures, or inferring trunk failures from circuit alarms; inferring the location of major network outages by topologically correlating multiple trunk failures; and filtering alarm reporting to the Fault Management System users such that only the most significant derived or inferred conditions are automatically displayed.
