Abstract
A system and method for managing faults in a data transmission system that includes a data path for transmitting signals containing data, and a plurality of application cards located along the data path for processing the signals. The method includes the steps of detecting the occurrence of a fault of a particular type at one of a plurality of points along the data transmission path; in response, the application card generating a fault report for the purpose of identifying the cause of the detected fault; and, preventing the generation by the application card of subsequent fault reports relating to that particular type of fault until receiving a signal indicating that fault report generation may be reenabled. In the fault management system, the data transmission system also includes at least one unit controller for controlling the application cards, and at least one system manager for controlling the at least one unit controller. The system further includes application card software residing on the plurality of application cards, unit controller software residing on the at least one unit controller, and system manager software residing on the at least one system manager. The applic…
