TR-069 is a technical specification defined by the Broadband Forum, which defines a
mechanism that encompasses secure auto-configuration of a CPE (Customer-Premises
Equipment), and incorporates other CPE management 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.
TR-069 is intended to support a variety of functionalities to manage a collection of CPEs,
including the following primary capabilities:
 Auto-configuration and dynamic service provisioning
 Software or firmware image management
 Status and performance monitoring
 Diagnostics
