1 Introduction
This user manual describes the features and how to configure a Virtual Access
GW2020 Series router.
The Virtual Access GW2020 Series router is a versatile 3G/4G LTE/CDMA450
wireless router suitable for a variety of business and industrial deployments. The
compact and rugged structure makes it a suitable product for deployments in
M2M applications such as CCTV, ATM, telemetry, SCADA, retail (POS), digital
signage, and intelligent traffi c systems. The product line supports the following
radio access technologies: HSPA+, HSPA, UMTS, EDGE, CDMA450, GPRS and
GSM.
3G is the third generation of mobile phone standards and technology. It is based
on the International Telecommunication Union (ITU) family of standards under
the International Mobile Telecommunications programme, IMT-2000.
4G is a mobile communications standard intended to replace 3G, allowing
wireless internet access at a much higher speed.
3G and 4G technologies enable network operators to offer users a wider range of
more advanced services, while achieving greater network capacity through
improved spectral effiecieny. Services include wide-area wireless voice
telephony, video calls, and broadband wireless data, all in a mobile environment.
1.1 Document scope

_______________________________________________________________________________________________________
6 Factory configuration extract ion from SIM c ar d
Virtual Access routers have a feature to update the factory configuration from a
SIM card. This allows you to change the factory configuration of a router when
installing the SIM.
1. Make sure the SIM card you are inserting has the required configuration written on it.
2. Ensure the router is powered off.
3. Hold the SIM 1 card with the chip side facing down and the cut corner front left.
4. Gently push the SIM card into SIM slot 1 until it clicks in.
5. Power up the router.
Depending on the model, the power LED and/or the configuration LED flash as
usual.
The SIM LED starts flashing. This indicates the application responsible for 3G and
configuration extraction management is running. It also means the update of the
configuration is happening.
When the update is finished, depending on the model, the power LED and/or the
configuration LED blink alternatively and very fast for 20 seconds.

8.2 Upgrading fir mware using CLI
To upgrade firmware using CLI, you will need a TFTP server on a connected PC.
Open up an SSH or Teln et sess ion to the router.
Enter in the relevant username and password.
To change into the temp folder, enter:
cd /tmp
To connect to your TFTP s er ver, enter:
atftp x.x.x.x
(where x.x.x.x is the IP of your PC).
Press Enter.
While in the TFTP application, to get the image, enter:
get GIG-15.00.38.image
Note: this is an example, substitute the correct file name.
When the image has downloaded, to leave TFPT and get back into the command
line, enter:
quit
To write the image into the alternative image, enter:
mtd write GIG-15.00.38.image altimage
Note: this is an example, substitute the correct file name.

9 File system
9.1 Configurations
Configurations are stored in folders at:
/etc/conf/factconf,
/etc/conf/config1
and
/etc/conf/config2
Multiple configuration files exist in each folder. Each file contains configuration
parameters for different areas of functionality in the system.
A symbolic link exists at:
/etc/conf/config, which always points to one of factconf, config1 or config2.
Files that appear to be in /etc/conf/config are actually in
/etc/conf/factconf|config1|config2 depending on which configuratio n is
active.
If /etc/conf is missing on start-up, for example on first boot, the links and
directories are created with configuration files copied from
/overlay/etc/config/.
At any given time, only one of the configurations is the active configuration.
To show the active configuration file, enter:
root@VA_router:~# vacmd show current config
To set the boot configuration to run on next reboot, enter:
root@VA_router:~# vacmd set next config [factconf|config1|config2]
9.1.1 High level configuration commands
To show the configuration currently running, enter:
