TR-069 (Technical Report 069) is a technical standard developed by the Broadband Forum that defines a communication protocol for remote management of customer-premises equipment (CPE) in a broadband network. TR-069 is designed to allow an Internet Service Provider (ISP) to remotely manage and configure CPEs such as modems, routers, and other devices connected to a broadband network.
Here is a step-by-step description of how TR-069 works:
- The CPE establishes a connection to the ISP's Auto Configuration Server (ACS) using the TR-069 protocol. This connection is typically initiated when the CPE is powered on or when the CPE's IP address changes.
- The CPE sends a request to the ACS to start a session. This request includes information about the CPE's manufacturer, model, and firmware version, as well as its current configuration.
- The ACS responds to the request by sending a request to the CPE to download and install any available software or firmware updates. The ACS may also send other requests to the CPE to configure or modify its settings.
- The CPE responds to the ACS's requests by downloading and installing the updates or modifying its settings as directed.
- The ACS and CPE continue to communicate throughout the session, exchanging information and requests as needed.
- When the session is complete, the CPE sends a request to the ACS to end the session. The ACS responds by acknowledging the request and closing the session.
Overall, TR-069 allows ISPs to remotely manage and configure CPEs connected to their network, enabling them to easily maintain and update these devices without requiring on-site visits or manual intervention. This can help ISPs improve the reliability and performance of their networks and reduce operational costs.
