1. A method, performed by equipment operative in a network, of performing a Network Resource Management (NRM) Fault Management (FM) procedure, the method comprising:
maintaining a NRM Information Object Class (IOC) ManagedElement object comprising one or more NRM IOC ManagedFunction objects, each ManagedFunction object configured to detect, report, and log faults;
maintaining for each ManagedFunction object:
a NRM IOC FMControl object comprising attributes indicating:
an administrative state of the FMControl object configured to be set and reset to start and stop, respectively, fault detection, reporting, and logging;
an operational state of the FMControl object; and
a fault report target identifying one or more addresses where the ManagedFunction object is to send fault reports;
one or more NRM faultTypeList objects, each faultTypeList object comprising attributes specifying types of faults that can be detected and reported by the ManagedFunction object; and
a NRM currentFaultList object comprising current fault information;
verifying the types of faults the ManagedFunction object is capable of detecting, reporting, and logging, and setting the administrative state attribute of the FMControl object to control the ManagedFunction object to detect faults and send the fault reports;
responsive to a network Management System setting the administrative state attribute of the FMControl object, and if the operational state attribute of the FMControl object is set, detecting, reporting, and logging the faults; and
sending the fault reports to the one or more addresses specified in the fault report target attribute of the FMControl object.
