Abstract:
1. A machine-implemented method of logging detected protection system related events which affect a protection system in communication equipment, the method comprising: determining whether a detected event itself or in combination with a previous detected event provides information relating to a protection switching operation and a cause of the protection switching operation; determining whether the information relating to a protection switching operation indicates that the protection switching operation has occurred, where a detected event itself or in combination with a previous detected event provides information relating to a protection switching operation and a cause of the protection switching operation; recording in an event log a log entry associated with the protection switching operation including at least a portion of the information relating to the cause of the protection switching operation where the detected event itself or in combination with a previous detected event provides information relating to a protection switching operation and a cause of the protection switching operation and the information relating to the protection switching operation indicates that a protection switching operation has occurred; and clearing a log entry for the previous detected event where the detected event in combination with the previous detected event provides information relating to a protection switching operation and a cause of the protection switching operation and the information relating to the protection switching operation indicates that a protection switching operation has not occurred.
