Basic CWMP functions
The ACS identifies different categories of CPEs by provision code. You can use the ACS to autoconfigure
and upgrade each category of CPEs in bulk.
Autoconfiguration
You can create configuration files for different categories of CPEs on the ACS. The ACS identifies the
configuration file for a CPE by its provision code.
The following are methods available for the ACS to issue configuration to the CPE:
• Transfers the configuration file to the CPE, and specifies the file as the next-startup configuration file.
At a reboot, the CPE starts up with the ACS-specified configuration file.
• Runs the configuration in the CPE's RAM. The configuration takes effect immediately on the CPE. For
the running configuration to survive a reboot, you must save the configuration on the CPE.
Software image management
The ACS can manage CPE software upgrade.
When the ACS finds a software version update, the ACS notifies the CPE to download the software
image file from a specific location. The location can be the URL of the ACS or an independent file server.
The CPE notifies the ACS of the download result (success or failure) when it completes a download
attempt. The CPE downloads the specified image file only when the file passes validity verification.
Data backup
The ACS can require the CPE to upload a configuration or log file to a specific location. The destination
location can be the ACS or a file server.
Status and performance monitoring
The CPE allows the ACS to monitor the status and performance objects in Table 22.
