Chapter 1 Introduction
The VR-3030 is a Multi-DSL router that supports both ADSL2+ and VDSL2. The
latter is a brand new standard and technology perfect for triple play (Video, Voice
and Data) applications. The VR-3030 comes with one 10/100 Base-T Ethernet
port.
The VR-3030 is a cost effective solution designed to meet the needs of ISPs and
carriers planning on deploying a single DSL device for covering end users in different
loop range areas. Deploying VR-3030 is cost effective for ISPs and carriers because
deploying a single CPE DSL device with multiple profile support minimizes the
number of required upgrades.

Chapter 2 Installation
2.1 Hardware Setup
Follow the instructions below to complete the hardware setup.
Non-stackable
This device is not stackable – do not place units on top of each other, otherwise
damage could occur.
BACK PANEL
The figure below shows the back panel of the device.
Power ON
Press the power button to the OFF position (OUT). Connect the power adapter to the
power port. Attach the power adapter to a wall outlet or other AC source. Press the
power button to the ON position (IN). If the Power LED displays as expected then
the device is ready for setup (see section 2.2 LED Indicators).
Caution 1: If the device fails to power up, or it malfunctions, first verify that the
power cords are connected securely and then power it on again. If the
problem persists, contact technical support.
Caution 2: Before servicing or disassembling this equipment, disconnect all power
cords and telephone lines from their outlets.
Reset Button
Restore the default parameters of the device by pressing the Reset button for 5
seconds. After the device has rebooted successfully, the front panel should display
as expected (see section 2.2 LED Indicators for details).
NOTE: If pressed down for more than 20 seconds, the VR-3030 will go into a
firmware update state (CFE boot mode). The firmware can then be
updated using an Internet browser pointed to the default IP address.

7
Ethernet (LAN) Port
Use a 10/100 BASE-T RJ-45 cable to connect to a network device. The ports is
auto-sensing MDI/X; so either straight-through or crossover cable can be used.
DSL Port
Connect to an ADSL2/2+ or VDSL with this RJ11 Port. This device contains a micro
filter which removes the analog phone signal. If you wish, you can connect a
regular telephone to the same line by using a POTS splitter.

8

Chapter 3 Web User Interface
This section describes how to access the device via the web user interface (WUI)
using an Internet browser such as Internet Explorer (version 5.0 and later).
3.1 Default Settings
The factory default settings of this device are summarized below.
• LAN IP address: 192.168.1.1
• LAN subnet mask: 255.255.255.0
• Administrative access (username: root, password: 12345)
• User access (username: user, password: user)
• Remote (WAN) access (username: support, password: support)
Technical Note
During power on, the device initializes all settings to default values. It will then
read the configuration profile from the permanent storage section of flash memory.
The default attributes are overwritten when identical attributes with different values
are configured. The configuration profile in permanent storage can be created via
the web user interface or telnet user interface, or other management protocols.
The factory default configuration can be restored either by pushing the reset button
for more than five seconds until the power indicates LED blinking or by clicking the
Restore Default Configuration option in the Restore Settings screen.

10
3.2 IP Configuration
DHCP MODE
When the VR-3030 powers up, the onboard DHCP server will switch on. Basically,
the DHCP server issues and reserves IP addresses for LAN devices, such as your PC.
To obtain an IP address from the DCHP server, follow the steps provided below.
NOTE: The following procedure assumes you are running Windows XP.
However, the general steps involved are similar for most operating
systems (OS). Check your OS support documentation for further details.
STEP 1: From the Network Connections window, open Local Area Connection (You
may also access this screen by double-clicking the Local Area Connection
icon on your taskbar). Click the Properties button.
STEP 2: Select Internet Protocol (TCP/IP) and click the Properties button.
STEP 3: Select Obtain an IP address automatically as shown below.
STEP 4: Click OK to submit these settings.
If you experience difficulty with DHCP mode, you can try static IP mode instead.

11
STATIC IP MODE
In static IP mode, you assign IP settings to your PC manually.
Follow these steps to configure your PC IP address to use subnet 192.168.1.x.
NOTE: The following procedure assumes you are running Windows XP.
However, the general steps involved are similar for most operating
systems (OS). Check your OS support documentation for further details.
STEP 1: From the Network Connections window, open Local Area Connection (You
may also access this screen by double-clicking the Local Area Connection
icon on your taskbar). Click the Properties button.
STEP 2: Select Internet Protocol (TCP/IP) and click the Properties button.
STEP 3: Change the IP address to the 192.168.1.x (1<x<255) subnet with subnet
mask of 255.255.255.0. The screen should now display as shown below.
STEP 4: Click OK to submit these settings.

12
3.3 Login Procedure
Perform the following steps to login to the web user interface.
NOTE: The default settings can be found in section 3.1 Default Settings.
STEP 1: Start the Internet browser and enter the default IP address for the device
in the Web address field. For example, if the default IP address is
192.168.1.1, type http://192.168.1.1.
NOTE: For local administration (i.e. LAN access), the PC running the browser
must be attached to the Ethernet, and not necessarily to the device.
For remote access (i.e. WAN), use the IP address shown on the Device
Information screen and login with remote username and password.
STEP 2: A dialog box will appear, such as the one below. Enter the default
username and password, as defined in section 3.1 Default Settings.
Click OK to continue.
NOTE: The login password can be changed later (see section 7.6.1 Passwords).

13
STEP 3: After successfully logging in for the first time, you will reach this screen.

Chapter 4 Device Information
The web user interface window is divided into two frames, the main menu (at left)
and the display screen (on the right). The main menu has several options and
selecting each of these options opens a submenu with more selections.
NOTE: The menu items shown are based upon the configured connection(s) and
user account privileges. For example, if NAT and Firewall are enabled, the
main menu will display the NAT and Security submenus. If either is
disabled, their corresponding menu(s) will also be disabled.
