1Introduction
Based on the very latest ADSL2+, WiFi and 3G HSPA+ technology, Virtual Access
GW6600 Series routers address the needs of today’s businesses for managed resilient
broadband connectivity. Point of Sale (POS), retail branch office, security monitoring and
other key business applications demand managed connectivity that is cost-effective, high
performance and resilient to network outage or last mile circuit failure.
Designed for managed network providers, GW6600 Series routers provide secure WAN
connectivity for internet and private networking environments over both ADSL2+ and 3G
broadband paths and incorporate optional 802.11n WiFi connectivity.
1.1 Document scope
This document covers the following GW6600 Series models.

1.2 Using this documentation
You can configure your router using either the router’s web interface or via the command
line using UCI commands. Each chapter explains first the web interface settings,
followed by how to configure the router using UCI. The web interface screens are shown
along with a path to the screen for example, ‘In the top menu, select Service ->
SNMP.’ followed by a screen grab.
After the screen grab there is an information table that describes each of the screen’s
fields.

1.2.1 Information tables
We use information tables to show the different ways to configure the router using the
router’s web and command line. The left-hand column shows three options:
•Web: refers the command on the router’s web page,
•UCI:shows the specific UCI command, and
•Opt: shows the package option.
The right-hand column shows a description field that describes the feature’s field or
command and shows any options for that feature.
Some features have a drop-down menu and the options are described in a table within
the description column. The default value is shown in a grey cell.
Values for enabling and disabling a feature are varied throughout the web interface, for
example, 1/0; Yes/No; True/False; check/uncheck a radio button. In the table
descriptions, we use 0to denote Disable and 1to denote Enable.
Some configuration sections can be defined more than once. An example of this is the
routing table where multiple routes can exist and all are named ‘route’. For these
sections, the UCI command will have a code value [0] or [x] (where x is the section
number) to identify the section.
Web Field/UCI/Package Option
Description
Web: Metric
UCI: network.@route[0].metric
Opt: metric
Specifies the route metric to use.
Note: these sections can be given a label for identification when using UCI or package
options.
network.@route[0]=route
network.@route[0].metric=0
can be witten as:
network.routename=route
network.routename.metric=0
However the documentation usually assumes that a section label is not configured.
The following table shows fields from a variety of chapters to illustrate the explanations
above.

Table 1: Example of an information table
1.2.2 Definitions
Throughout the document, we use the host name ‘VA_router’ to cover all router models.
UCI commands and package option examples are shown in the following format:
root@VA_router:~# vacmd show current config
1.2.3 Diagnostics
Diagnostics are explained at the end of each feature’s chapter.
1.2.4 UCI commands
For detailed information on using UCI commands, read chapters ‘Router File Structure’
and ‘Using Command Line Interface’.

2.8 Antenna
The GW6600 Series and GW6600V Series routers have four SMA connectors for
connection of up to four antennas for antenna diversity. Antenna diversity helps improve
the quality of a wireless link by mitigating problems associated with multipath
interference.
2.9 Components
To enable and configure connections on your router, it must be correctly installed.
The GW6600 Series router contains an internal web server that you use for
configurations. Before you can access the internal web server and start the
configuration, ensure the components are correctly connected and that your PC has the
correct networking setup.
All GW6600 Series routers come with the following components as standard:
1 x GW6600 Series router (models vary)
1 x Ethernet cable RJ45 to RJ45 (yellow).
1 x ADSL cable: RJ11 to RJ11 (purple)
1 x 12V power supply unit (2 parts).

2.15 Powering up
Plug the power cable into an electrical socket suitable for the power supply.
The GW6600 takes approximately 2 minutes to boot up. During this time, the power LED
flashes.
Other LEDs display different diagnostic patterns during boot up.
Booting is complete when the power LED stops flashing and stays on steady.
2.16 Reset button
The reset button is used to request a system reset.
When you press the reset button all LEDs turn on simultaneously. The length of time you
hold the reset button will determine its behaviour.
Press Duration
Behaviour
Less than 2 seconds
Normal reset.
Between 2 and 15 seconds The router resets to factory configuration.
Between 20 seconds and 30 seconds
Recovery mode.
Over 30 seconds
Normal reset.
2.16.1 Recovery mode
Recovery mode is a fail-safe mode where the router can load a default configuration
from the routers firmware. If your router goes into recovery mode, all config files are
kept intact. After the next reboot, the router will revert to the previous config file.
You can use recovery mode to manipulate the config files, but should only be used if all
other configs files are corrupt. If your router has entered recovery mode, contact your
local reseller for access information.

4Factory configuration extraction from SIM card
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.
