An operational support system (OSS) is a collection of computer programs or information technology (IT) system used by communications service providers to monitor, control, analyze, and manage a computer or telephone network system.
OSS software is designed specifically for telecommunications service providers and is primarily used to support network processes such as network inventory management, network component configuration, service provisioning, and fault management.
With the proliferation of new broadband and Voice over Internet Protocol (VoIP) systems, OSS and network management are increasingly being applied to home networks.
An OSS is also referred to as a business support system (BSS).
