TR-069

From Wikipedia, the free encyclopedia

TR-069 (short for Technical Report 069) is a DSL Forum technical specification entitled CPE WAN Management Protocol (CWMP). It defines an internet protocol for remote management of home network devices and terminals.

As a bidirectional SOAP/HTTP based protocol it provides the communication between CPE and Auto Configuration Servers (ACS). It includes both a safe auto configuration and the control of other CPE management functions within an integrated framework. In the course of the boom of the broadband market, the number of different Internet access possibilities grew as well (e.g. modems, routers, gateways, Set-top box, paddles, VoIP-phones). At the same time the configuration of this equipment became more complicated -- too complicated for the end-users. For this reason the TR-069 standard was developed. It provides the possibility of auto configuration of these access types. The technical specifications are managed and published by the DSL Forum. Using TR-069 the terminals can get in contact with the Auto Configuration Servers (ACS) and establish the configuration automatically. Accordingly other service functions can be provided. TR-069 is the current standard for activation of terminals in the range of DSL broadband market. Other fora, such as Home Gateway Initiative (HGI) and DVB, are endorsing CWMP as the protocol for remote management of home network devices (e.g. the HGI gateway) and terminals (e.g. the DVB IPTV STB).

In the future TR-069 will control many additional options of the CPEs additionally to the pure standards for activation:

  • enquiry of the equipment functions
  • enquiry of information, diagnostics, status and capacity
  • firmware management
  • automatic process-controlled alarm
  • irrespective gateway data model, in access with TR-064 it is upgradeable with secondary equipment and functions

TR-069 ACS provides Element Management functionalities as the entry point for the Operational Support Systems architectures.
