FCAPS

FCAPS is an acronym for Fault, Configuration, Accounting, Performance, and Security.

These are the five functional areas of network management defined by the ISO Telecommunications Management Network model and framework. FCAPS is used to classify, organize, and standardize the tasks and processes involved in managing and operating a network. These include detecting and resolving errors, configuring and updating devices, monitoring and measuring traffic, and ensuring the integrity and availability of the network.

OSS stands for Operations Support System, which is a generic term for a set of software applications and tools that enable a service provider to manage and optimize its network and services. OSS can perform various functions, such as service provisioning, service assurance, service fulfillment, service inventory, etc. OSS can also interact with other systems, such as Business Support System (BSS), Element Management System (EMS), and Network Management System (NMS), to provide a comprehensive and integrated solution for network management.

FCAPS and OSS are related in the sense that FCAPS provides the conceptual framework and categories for OSS to implement and execute. OSS can use the FCAPS model to define the scope and objectives of its functions and processes, and to align them with the network management requirements and standards. For example, OSS can use the fault management function of FCAPS to detect, isolate, and correct network failures, and to notify the network operators and customers about the status and resolution of the faults. Similarly, OSS can use the configuration management function of FCAPS to control and maintain the network configuration, and to ensure the compatibility and interoperability of the network devices and systems. OSS can also use the accounting management function of FCAPS to collect and process the usage and billing data of the network and services, and to generate reports and invoices for the customers and stakeholders. Furthermore, OSS can use the performance management function of FCAPS to monitor and measure the network performance and quality of service, and to identify and resolve any issues or bottlenecks that may affect the network efficiency and reliability. Finally, OSS can use the security management function of FCAPS to protect the network and data from unauthorized access, attacks, or damage, and to enforce the network policies and regulations.
