TR-181 is a technical specification developed by the Broadband Forum that defines a data model for managing and monitoring broadband devices. It provides a standardized way for service providers to access and control various aspects of customer premises equipment (CPE), such as routers and gateways. The specification is designed to facilitate interoperability between different devices and systems, ensuring that they can communicate effectively. By using TR-181, service providers can improve their operational efficiency and enhance the customer experience through better management of network resources and services.
