ET685 Administrator and Provisioning Manual
Description:
This setting enables a software update to be done using a USB storage. If
the setting is on and a USB storage is plugged in which hold a VTech
firmware in the root directory, the phone will indicate that a software update
is available and the user can chose to install it. If the USB storage holds
more that one firmware for the phone type, the first one will be picked and
no selection will be shown. The setting requires administrator mode. The
feature is available on VTech phones with a USB port.
Values:
on, off
Default:
off
Setting:
usb_storage_syslog
Description:
This setting enables a log trace of the phone to be logged on a USB
storage. This is an administrator feature which allows you to track all kind
of issues connected with the phone or the network traffic or SIP signalling.
The file holds the regular log which can also be seen on the web interface.
But the log on the USB storage is only limited by the size of the storage.
The log is continuous. So it is possible to capture events which happen
rarely. In order to start the logging the USB storage should hold the file
syslog.flg in the root directory. So a log is not automatically saved to every
USB storage that is plugged in. The setting must be on and a USB storage
with the flag file syslog.flg must be inserted to start the log. We recommend
that the file on the USB storage is encrypted by also setting
usb_storage_passphrase. Encrypting the file is highly recommended,
otherwise anyone could unplug the USB storage an analyse the data. The
feature is available on VTech phones with a USB port.
Starting from firmware version 8.7.5.22, the loglevel can be set via an
additional file syslog.lvl. It should contain a single byte with the ascii code
of the desired loglevel.
Values:

additionally possible to adjust the intensity of the backlight in active and
idle mode.
