existing 802.11b, 802.11g, and 802.11n PCI, USB and Cardbus adapters.
DHCP Support - Dynamic Host Configuration Protocol automatically and dynamically assigns all LAN IP settings to each host on your network. This eliminates the need
to reconfigure every host whenever changes in network topology occur.
Network Address Translation (NAT) - For small office environments, the router allows multiple users on the LAN to access the Internet concurrently through a single
Internet account. This provides Internet access to everyone in the office for the price of a single user. NAT improves network security in effect by hiding the private
network behind one global and visible IP address. NAT address mapping can also be used to link two IP domains via a LAN-to-LAN connection.
Precise ATM Traffic Shaping - Traffic shaping is a method of controlling the flow rate of ATM data cells. This function helps to establish the Quality of Service for ATM
data transfer.
High Performance - Very high rates of data transfer are possible with the router. Up to 100Mbps downstream bit rate using the G.dmt standard. (For VDSL2+)
Full Network Management - The router incorporates SNMP (Simple Network Management Protocol) support for web-based management and text-based network
management via a Telnet connection.
Easy Installation - The router uses a web-based graphical user interface program for convenient management access and easy set up. Any common web browsing
software can be used to manage this router.
USB Support- The router provides a 3.0 USB port to easily share files and printers. The router supports a USB storage option that shares files through a SAMBA file
server and in addition also supports sharing USB printers to network members. Please note that the USB storage device is not included in this package and must be
bought separately.
Maximum wireless signal rate derived from IEEE standard 802.11n specifications. Actual data throughput will vary. Network conditions and environmental factors, including volume of network traffic, building

Basic Installation
Page 8
Basic Installation
This section will walk you through the installation process. Placement of the router is very important. Do not place the router in an enclosed area such as a closet, cabinet, or
in the attic or garage.
Before You Begin
Please read and make sure you understand all the prerequisites for proper installation of your new router. Have all the necessary information and equipment on hand before
beginning the installation.
Installation Notes
In order to establish a connection to the Internet it will be necessary to provide information to the router that will be stored in its memory. For some users, only their account
information (Username and Password) is required. For others, various parameters that control and define the Internet connection will be required.
Low Pass Filters
Since VDSL and telephone services share the same copper wiring to carry their respective signals, a filtering mechanism may be necessary to avoid mutual interference. A
low pass filter device can be installed for each telephone that shares the line with the VDSL line. These filters are easy to install passive devices that connect to the VDSL
device and/or telephone using standard telephone cable. Ask your service provider for more information about the use of low pass filters with your installation.
Operating Systems
The router uses an HTML-based web interface for setup and management. The Web configuration manager may be accessed using any operating system capable of running
web browser software, including Windows®, Macintosh, and Linux-based Operating Systems.
Web Browser
Any common Web browser can be used to configure the router using the Web configuration management software. The program is designed to work best with more recently
released browsers such as Internet Explorer 7 or higher, Firefox 3.5 or higher, Safari 4 or higher, or Chrome 8 or higher.. The Web browser must have JavaScript enabled.
JavaScript is enabled by default on many browsers. Make sure JavaScript has not been disabled by other software (such as virus protection or web user security packages)
that may be running on your computer.
Ethernet Port (NIC Adapter)
Any computer that uses the router must be able to connect to it through one of the Ethernet ports on the router. This connection is an Ethernet connection and therefore
requires that your computer be equipped with an Ethernet port as well. Most notebook computers are now sold with an Ethernet port already installed. Likewise, most fully
assembled desktop computers come with an Ethernet adapter as standard equipment. If your computer does not have an Ethernet port, you must install an Ethernet NIC
adapter before you can use the router. If you must install an adapter, follow the installation instructions that come with the Ethernet NIC adapter.

Additional Software
It may be necessary to install software on your computer that enables the computer to access the Internet. Additional software must be installed if you are using the device a
simple bridge. For a bridged connection, the information needed to make and maintain the Internet connection is stored on another computer or gateway device, not in the
router itself.
If your VDSL service is delivered through a PPPoE or PPPoA connection, the information needed to establish and maintain the Internet connection can be stored in the
router. In this case, it is not necessary to install software on your computer. It may however be necessary to change some settings in the device, including account information
used to identify and verify the connection.
All connections to the Internet require a unique global IP address. For bridged connections, the global IP settings must reside in a TCP/IP enabled device on the LAN side of
the bridge, such as a PC, a server, a gateway device such as a router or similar firewall hardware. The IP address can be assigned in a number of ways. Your network
service provider will give you instructions about any additional connection software or NIC configuration that may be required.

Information you will need from your VDSL service provider
Username
This is the Username used to log on to your VDSL service provider’s network. Your VDSL service provider uses this to identify your account.
Password
This is the Password used, in conjunction with the Username above, to log on to your VDSL service provider’s network. This is used to verify the identity of your account.
WAN Setting / Connection Type
These settings describe the method your VDSL service provider uses to transport data between the Internet and your computer. Most users will use the default settings. You
may need to specify one of the following WAN Setting and Connection Type configurations (Connection Type settings listed in parenthesis):
PPPoE/PPPoA (PPPoE LLC, PPPoE VC-Mux, PPPoA LLC or PPPoA VC-Mux)
Static IP Address (1483 Routed IP LLC or 1483 Routed IP VC-Mux)
Bridge Mode (1483 Bridged IP LLC or 1483 Bridged IP VC Mux)
Modulation Type
VDSL uses various standardized modulation techniques to transmit data over the allotted signal frequencies. Some users may need to change the type of modulation used for
their service. The default DSL modulation (Autosense) used for the router automatically detects all types of VDSL, VDSL2, and VDSL2+ modulation.
Security Protocol
This is the method your VDSL service provider will use to verify your Username and Password when you log on to their network. Your router supports the PAP and CHAP
protocols.
VPI
Most users will not be required to change this setting. The Virtual Path Identifier (VPI) is used in conjunction with the Virtual Channel Identifier (VCI) to identify the data path
between your VDSL service provider’s network and your computer. If you are setting up the router for multiple virtual connections, you will need to configure the VPI and VCI
as instructed by your VDSL service provider for the additional connections. This setting can be changed in the WAN Settings window of the web management interface.
VCI
Most users will not be required to change this setting. The Virtual Channel Identifier (VCI) used in conjunction with the VPI to identify the data path between your VDSL
service provider’s network and your computer. If you are setting up the router for multiple virtual connections, you will need to configure the VPI and VCI as instructed by your
VDSL service provider for the additional connections. This setting can be changed in the WAN Settings window of the web management interface.

this username. The default username for the router is “Admin”. Alternatively, you can also try “user”
Password
This is the password you will be prompted to enter when you access the router’s web management interface. The default password is “Admin”. Alternatively, you can also try
“user”
LAN IP Addresses for the Router
This is the IP address you will enter into the Address field of your web browser to access the router’s configuration Graphical User Interface (GUI) using a web browser. The
default IP address is 10.0.0.138. This may be changed to suit any IP address scheme the user desires. This address will be the base IP address used for DHCP service on
the LAN when DHCP is enabled.
LAN Subnet Mask for the Router
This is the subnet mask used by the Router, and will be used throughout your LAN. The default subnet mask is 255.255.255.0. This can be changed later.
Information you will need about your LAN or computer
Ethernet NIC
If your computer has an Ethernet NIC, you can connect the router to this Ethernet port using an Ethernet cable. You can also use the Ethernet ports on the router to connect
to other computer or Ethernet devices.
DHCP Client status
Your VDSL router is configured, by default, to be a DHCP server. This means that it can assign an IP address, subnet mask, and a default gateway address to computers on
your LAN. The default range of IP addresses the unit will assign are from 10.0.0.139 to 10.0.0.254. Your computer (or computers) needs to be configured to obtain an IP
address automatically (that is, they need to be configured as DHCP clients.)
Once you have the above information, you are ready to setup and configure your VDSL router.

Device Installation
The router connects two separate physical interfaces, a VDSL (WAN) and an Ethernet (LAN) interface. Place the router in a location where it can be connected to the various
devices as well as to a power source. The router should not be located where it will be exposed to moisture or excessive heat. Make sure the cables and power cord are
placed safely out of the way so they do not create a tripping hazard. As with any electrical appliance, observe common sense safety procedures.
The router can be placed on a shelf or desktop, ideally you should be able to see the LED indicators on the front if you need to view them for troubleshooting.
Power on Router
The router must be used with the power adapter included with the device.
1. Insert the AC Power Adapter cord into the power receptacle located on the rear panel of the router and plug the adapter into a suitable nearby power source.
2. Press the Power button into the on position. You should see the Power LED indicator light up and remain lit.
3. If the Ethernet port is connected to a working device, check the Ethernet LED indicators to make sure the connection is valid. The router will attempt to establish the
VDSL connection, if the VDSL line is connected and the router is properly configured this should light up after several seconds. If this is the first time installing the
device, some settings may need to be changed before the router can establish a connection.
Factory Reset Button
The router may be reset to the original factory default settings by using a ballpoint pen or paperclip to gently push down the reset button in the following sequence:
1. Press and hold the reset button while the device is powered on for 10-15 seconds.
2. Release the reset button.
Remember that this will wipe out any settings stored in flash memory including user account information and LAN IP settings. The device settings will be restored to the
factory default IP address 10.0.0.138 and the subnet mask is 255.255.255.0. The default management username is “user” and the default password is “user”.

Network Connections
Connect VDSL Line
Use the VDSL cable included with the router to connect it to a telephone wall socket or receptacle. Plug one end of the cable into the VDSL port (RJ-11 receptacle) on the
rear panel of the router and insert the other end into the RJ-11 wall socket. If you are using a low pass filter device, follow the instructions included with the device or given to
you by your service provider. The VDSL connection represents the WAN interface, the connection to the Internet. It is the physical link to the service provider’s network
backbone and ultimately to the Internet.
Connect Router to Ethernet
The router may be connected to a single computer or Ethernet device through the Ethernet ports on the rear panel. Any connection to an Ethernet concentrating device such
as a switch or hub must operate at a speed of 10/100Mbps. When connecting the router to any Ethernet device that is capable of operating at speeds higher than 10Mbps, be
sure that the device has auto-negotiation (NWay) enabled for the connecting port. Use standard twisted-pair cable with RJ-45 connectors. The RJ-45 ports on the router are a
crossed port (MDI-X). Follow standard Ethernet guidelines when deciding what type of cable to use to make this connection. When connecting the router directly to a PC or
server use a normal straight-through cable. You should use a crossed cable when connecting the router to a normal (MDI-X) port on a switch or hub. Use a normal straight-
through cable when connecting it to an uplink (MDI-II) port on a hub or switch. The rules governing Ethernet cable lengths apply to the LAN to router connection. Be sure that
the cable connecting the LAN to the router does not exceed 100 meters.
Hub or Switch to Router Connection
Connect the router to an uplink port (MDI-II) on an Ethernet hub or switch with a straight-through cable. If you wish to reserve the uplink port on the switch or hub for another
device, connect to any on the other MDI-X ports (1x, 2x, etc.) with a crossed cable.
Computer to Router Connection
You can connect the router directly to an Ethernet adapter card (NIC) installed on a PC using the Ethernet cable provided.
