TR-069 Device Management
TR-069 is a technical specification defined by the Broadband Forum, which defines a mechanism that encom-
passes secure auto-configuration of a CPE (Customer-Premises Equipment), and incorporates other CPE man-
agement functions into a common framework. TR-069 uses common transport mechanisms (HTTP and HTTPS) for
communication between CPE and ACS (Auto Configuration Servers). The HTTP(S) messages contain XML-RPC
methods defined in the standard for configuration and management of the CPE.
For more information on TR-069, refer to Yealink TR-069 Technote.
