The 9502 includes an FTP client. The operator can send SMS messages or AT
commands to command the 9502 to send or retrieve files from an FTP server in the
network or Internet. This allows the 9502 to be upgraded, reconfigured and also
allows log files to be sent back to the server. The FTP server can be in the Inmarsat
network, e.g. accessible via a free APN for upgrades; or can be outside the Inmarsat
network, e.g. accessible via a normal APN for debugging and configuration changes.
The remote upgrade process uses download firmware and firmware upgrade
commands (see "Hughes 9502 SMS Remote Control Feature User Guide").
The Web UI includes an admin feature that can be activated from the security page
to prevent unauthorized access to the Web UI. Additionally the AT command port is
locked by default and the command: AT_ICLCK="AD",0,"<admin password>" must
be used to unlock it before AT commands can be used. Both mechanisms use the
same password but the AT commands port and each Web UI session use a separate
lock and must be individually unlocked.
Support for SMS Remote control is configured from the SMS settings page. Each
Remote Control SMS must include the correct password. Remote control SMS
containing AT commands will be processed regardless of the Admin setting (they
require the feature to be active and the correct SMS password.)
USIM personalization (or "Phone to SIM lock") can be used to lock the UT to a
particular SIM.
MAC address filtering on the Ethernet port page allows the user to define the MAC
address of TEs authorized to communicate via the Ethernet port. Note: The USB
port is not included in the MAC filtering and can be used if the proper USB driver is
installed on the TE.
The UT includes a special low power mode called Wake on LAN (any packet). From
the Web UI you can configure the UT to power down into this mode after a
configurable idle timer or time of day.
Wake on LAN operation is configured from the Ethernet Settings page
page 32) under the Settings tab. It includes a configurable idle timer to control
when the UT shuts down into the Wake on LAN mode. The UT declares the link idle
if no packets are received on the Ethernet port within the idle time.
Additionally, the UT can be configured to power down at a configurable time of day.
Enter UTC time as 0001 to 2400. Set to 0 to deactivate the time of day feature. Note
that the UT waits 5 minutes after startup before it checks the time of day to see if it
has to power off.
When the UT powers down into this mode it will disconnect from the BGAN
network and monitor the local Ethernet port and power up again if it sees any
Ethernet packet (ARP, DHCP, data packet, etc.). In this mode the power
