13.8 CWMP-TR069
CWMP-TR069 is an abbreviation of “ CPE WAN Management Protocol - Technical
Reference 069 ” , a protocol designed to facilitate the remote management of
Customer Premise Equipement (CPE), such as the OX253P. It can be managed
over a WAN by means of an Auto Configuration Server (ACS). CWMP-TR069 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 OX253P, modify its
settings, perform firmware upgrades, and monitor and diagnose it. In order to do
so, you must enable the CWMP-TR069 feature on your OX253P and then configure
it appropriately. (The ACS server which it will use must also be configured by its
administrator.)
Figure 63 CWMP-TR069 Example
In this example, the OX253P 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 OX253P remotely. All three servers are owned and operated by the
client
’ s Internet Service Provider. However, without the configuration settings from
the ACS, the OX253P cannot access the other two servers. Once the OX253P
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 OX253P can be configured to periodically check for updates from the auto-
configuration server so that the end user need not be worried about it.
