TR-069 describes a bi-directional remote management protocol for customer premise equipment (CPE), intended for communication between CPE and management entity known as an Auto-Configuration Server (ACS). It is intended to support a variety of functionalities to manage CPE, including auto-configuration and dynamic service provisioning, software/firmware management, status and performance monitoring and diagnostics.
CPE WAN Management Protocol, known as TR-069, is intended to support various functionalities to manage a collection of CPE:
1. Auto-Configuration and Dynamic Service Provisioning
TR-69 allows an ACS to provision a CPE or collection of CPE based on a variety of criteria. The provisioning mechanism includes specific provisioning parameters and a mechanism for adding vendor-specific provisioning capabilities as needed.
A. Initial CPE Configuration & Re-provision at Any Subsequent Time
The provisioning mechanism allows CPE provisioning at the very first time connecting to the broadband access network and the ability to re-provision at any subsequent time. This also includes support for asynchronous ACS-initiated re-provisioning of a CPE.
B. Allow vendor-specific parameter configuration
The TR-069 identification mechanism allows CPE provisioning based either on the requirements of each specific CPE or on collective criteria such as the CPE vendor, model, software version or other criteria.
2. Software/firmware image management
A. Version Identification
TR-069 provides mechanisms for CPE firmware version identification.
B. File Download Initiation
TR-069 protocol provides tools to manage to download of CPE software/firmware image files. File download can be initiated either from ACS or CPE (optional). TR-069 Protocol also defines a digitally signed file format that may optionally be used to download either individual files or a package of files along with explicit installation instructions for the CPE to perform. This signed package format ensures the integrity of downloaded files and the associated installation instructions, allowing authentication of a file source that may be a party other than the ACS operator.
C. Notification of the success or failure of a file download
TR-069 notification mechanism feedbacks the success or failure of a file download.
3. Status and performance monitoring
Should a service provider wish to monitor the performance or service status of the CPE, TR-069 supports functionality whereby the CPE can send statistics to the ACS. TR-069 defines a broad set of operational parameters and provides a standard syntax for vendors to define additional non-standard parameters, that an ACS can monitor. It also defines a set of conditions under which a CPE should actively notify the ACS of changes.
TR-069 supports functionality for a CPE to update availability information, that the ACS may use to determine the cause of connectivity malfunctions or service degradations. TR-069 defines a common set of such parameters and a general mechanism for adding vendor-specific diagnostic capabilities. You can use this feature to focus on a single device and collect diagnostics information for further analysis.
5. Logfile and Dynamic Notification
As TR-069 defines a broad set of operational parameters, operators are able to define certain conditions, that will trigger a notification from a CPE to the ACS.
