A network element state model facilitates cross domain network management and promotes a multi-vendor environment. The standard definitions and mappings allow operations systems to gather state information from NEs and integrate it into a consistent representation of the status of the entire managed network and each of the services that it supports.
FCAPS is the ISO Telecommunications Management Network model and framework for network management. FCAPS is an acronym for fault, configuration, accounting, performance, security, the management categories into which the ISO model defines network management tasks.
