TR-069
TR-069 is an abbreviation of “Technical Reference 069”, a protocol designed to facilitate the remote
management of Customer Premise Equipment (CPE), such as the BM2022w. It can be managed
over a WAN by means of an Auto Configuration Server (ACS). TR-069 is based on sending Remote
Procedure Calls (RPCs) between the ACS and the client device. RPCs are sent in Extensible Markup
Language (XML) format over HTTP or HTTPS.
An administrator can use an ACS to remotely set up the BM2022w, modify its settings, perform
firmware upgrades, and monitor and diagnose it. In order to do so, you must enable the TR-069
feature on your BM2022w and then configure it appropriately. (The ACS server which it will use
must also be configured by its administrator.)
Figure 103 TR-069 Example
In this example, the BM2022w receives data from at least 3 sources: A SIP server for handling
voice calls, an HTTP server for handling web services, and an ACS, for configuring the BM2022w
remotely. All three servers are owned and operated by the client’s Internet Service Provider.
However, without the configuration settings from the ACS, the BM2022w cannot access the other
two servers. Once the BM2022w receives its configuration settings and implements them, it can
connect to the other servers. If the settings change, it will once again be unable to connect until it
receives its updates from the ACS.
The BM2022w can be configured to periodically check for updates from the auto-configuration
server so that the end user need not be worried about it.
