complete software image. If a software update process should get
interrupted, e.g. power failure during the update process, there is always a
last known good firmware image to boot from.
Software updates can be performed either manually using the FTP or
HTTP(s) protocols, or automatically using TR-069 (CWMP).
9.4.1.1 Manual Software Update
Manual software updates is supported from FTP or HTTP(s) servers. The
image file can also be fetched from the local file system, which includes
whatever is mounted as USB storage.
When an update is initiated, the image file is downloaded using standard
TCP/IP protocol specified by the URL or path to a local file. Before the
update process is started, the file is checked for inconsistencies.
It is also possible to upgrade the software via a browse button in the WUI
from a local computer.
9.4.2 Remote Management using TR-069
The W3x terminals include a remote management agent supporting the
CPE WAN Management Protocol (CWMP) as specified in DSL Forum TR-
069 (short for Technical Report 069) Amendment II.
CWMP defines an application layer protocol for remote management of
end-user devices and provides the communication between a CPE and a
TR-069 capable Auto Configuration Server (ACS).
The W3x terminals are configured with parameters relating to the
association with an ACS, credentials for an ACS when making a connection
request to the W3x terminals as well as time settings for when the W3x
terminals should send CPE information to the ACS.
The W3x terminals remote management agent supports remote software
image installation, shell script execution and a set of configuration and
status parameters.
9.4.3 Backup and Restore Configuration
To preserve the running configuration, a backup copy of all accessible
values can be stored in a local file. In case of a system failure or a
corrupted configuration, the system can be restored from a backup file.
From the WUI, the end-user can backup and restore configuration files
to/from a local PC.
9.4.4 Reset to Default Configuration
A reset to default configuration can be done either from the CLI, WUI or by
using the physical Reset button on the unit.
9.4.4.1 Create own Default Configuration File
It is possible to save the running configuration as a new default
configuration file which then can be imported to the CDB.
