This
equipment complies with Part 68 of the FCC Rules. On the bottom
of this equipment is a label that contains the FCC Registration
Number and Ringer Equivalence Number (REN) for this equipment. You
must provide this information to the telephone company upon request.
The REN is useful to determine the quantity of devices you may connect
to the telephone line and still have all of those devices ring when
your number is called.
In most, but not all areas, the sum of the
REN of all devices connected to one line should not exceed five
(5.0). To be certain of the number of devices you may connect to
your line, as determined by the REN, you should contact your local
telephone company to determine the maximum REN for your calling
area.
If the modem causes harm to the telephone network, the telephone

Hardware installation
This section describes how to connect and configure the ADSL2+
wireless router.
Step 1. Connect the ADSL Line
Connect the router directly to the wall jack using the included ADSL
cable.
Step 2. Connect a Workstation to the Router's LAN port
There are two methods to connect the router and workstation. The one
use the crossover Ethernet cable to connect directly between them.
The other use straight Ethernet cable to connect router with hub (or
switch), then go to the workstation.
Step 3. Connect the Power Adapter to the Router
Connect the power adapter to the port labeled POWER on the rear
panel of router.
Step 4. Connect All Cables to the Network
The procedure for connecting cables differs depending on whether or
not your telephone equipment is connected to a POTS splitter.
POTS Splitter Configuration (ADSL over POTS)
A POTS splitter separates data signals from voice signals on your
telephone line. The POTS splitter works by running a separate data
line from the voice line,
so that the ADSL router has a dedicated
cable for data transmission. Figure 2-3.1 and 2-3.2 shows how to
connect all cables to the Router.

Figure 2-4.1 Router Connected through a POTS Splitter
Note:
The POTS splitter may also be installed on the outside of the house
adjacent to the telephone network interface device (NID).

Figure 2-4.2 Router Connected through several micro-filters
ISDN
Splitter Configuration (ADSL
over ISDN)
A ISDN splitter separates ADSL signals from ISDN signals on your
ISDN telephone line. The ISDN splitter works by running a separate
ADSL line from the ISDN line, so that the ADSL router has a
dedicated cable for data transmission. Figure 2-3.3 shows how to
connect all cables to the Router.

Figure 2-4.3 Router Connected through a ISDN Splitter
Note:
The
ISDN splitter may also be installed on the outside of the house
adjacent to the telephone network interface device (NID).
Chapter
3 Configuration
3.1 Determine your connection settings
Before you configure the router, you need to know the connection
information supplied by your ADSL service provider.
3.2 Connecting
the ADSL Router to your network
Unlike a simple hub or switch, the setup of the ADSL Router consists
of more than simply plugging everything together. Because the Router
acts as a DHCP server, you will have to set some values within the
Router, and also configure your networked PCs to accept the IP
Addresses the Router chooses to assign them.
Generally there are
several different operating modes for your applications. And you can
know which mode is necessary for your system from ISP.
These modes
are router, bridge, PPPoE+NAT and NAT and PPPoA+NAT.
3.3
Configuring with Web Browser
It
is advisable to change the administrator password to safeguard the
security of your network.
To
configure the router, open your browser, type 'http://192.168.16.1'
into the address bar and click 'Go' to get to the login page.
Save
this address in your Favorites for future reference.
At
the User name prompt, type 'admin'. And the Password prompt, type 'admin'. You can change these later
if you wish.
Click 'OK'.


3.3.1

WAN Configuration
Go
to Interface Setup -> Internet. The
router can be connected to your service provider in any of the
following ways.
Dynamic
IP Address: Obtain an IP address automatically from your service
provider.
Static
IP Address: Uses a static IP address. Your service provider gives a
static IP address to access Internet services.
PPPoE:
PPP over Ethernet is a common connection method used for xDSL
PPPoA:
PPP over ATM is a common connection method used for xDSL
Bridge:
Bridge mode is a common connection method used for xDSL modem.


3.5.2
WAN Status
Go
to Status -> Device Info and select the Virtual Circuit
to see the connection status.

3.5.3
DNS
Go
to Interface -> LAN to enable DHCP server. Then you can
set DNS server for the router. A Domain Name system (DNS)
server is like an index of IP addresses and Web addresses. If you
type a Web address into you browser, a DNS server will find that
name in its index and find the matching IP address.
Most ISPs provide a DNS server for speed and convenience. Since your
Service Provider many connect to the Internet with dynamic IP
settings, it is likely that the DNS server IP addresses are also
provided dynamically. However, if there is a DNS server that you
would rather use, you need to specify the IP address below.

3.5.4
DDNS
Go
to Access Management -> DDNS to setup your DDNS
parameters. Dynamic
DNS allows you to update your dynamic IP address with one or many
dynamic DNS services. So anyone can access your FTP or Web service
on your computer using DNS-like address.

3.6.1
LAN Configuration
Go
to Interface Setup -> LAN. The 'LAN Settings' option enables you to
configure the LAN port.
If
the DHCP Relay is selected, the DHCP requests from local PCs are forward to
the DHCP server runs on WAN side. To have this function working properly, disable
the NAT to run on router mode only, disable the DHCP server on the LAN port,
and make sure the routing table has the correct routing entry.

3.7.1
Wireless Settings
Go to Interface -> Wireless to setup the wireless
parameters.
SSID
The
identifier for the network. You can change the SSID. Only devices
with the same SSID can interconnect.
Channel
ID
The
channel number is used for wireless networking. The channel setting of the
wireless devices within a network should be the same.

3.7.2
Wireless Security
Go
to Interface -> Wireless to setup the wireless security.
The
Authentication type supports “shared key WEP 64bits", "shared key
WEP 128bits? “WPA-PSK?

3.8.1
NAT Setting
Go
to Advanced Setup->NAT to setup the NAT features. Network Address
Translation (NAT) allows multiple users at your local site to access
the Internet through a single public IP address or multiple public
IP addresses. NAT can also prevent hacker attacks by mapping local
addresses to public addresses for key services such as the Web or
FTP..

3.9.1
NAT Setting
Go
to Advanced Setup->NAT to setup the NAT features. Network Address
Translation (NAT) allows multiple users at your local site to access
the Internet through a single public IP address or multiple public
IP addresses. NAT can also prevent hacker attacks by mapping local
addresses to public addresses for key services such as the Web or
FTP.

3.9.2
Virtual Server
Go
to Advanced Setup ->NAT -> Virtual Server to set
virtual server as you need.(known as Port Mapping).
You can configure the
router as a virtual server so that remote users accessing services
such as the Web or FTP at your local site via public IP addresses
can
be automatically redirected to local servers configured with
private IP addresses. In other words, depending on the requested
service (TCP/UDP port numbers), the router redirects the external
service request to the appropriate server (located at another
internal IP address). For some applications,
you need to assign a set or a range of ports (example 4000-5000) to
a specified local machine to route the packets. The router allows
the user to configure the needed port mappings to suit such
applications.

3.9.3
DMZ Setting
Go
to Advanced Setup ->NAT -> DMZ to set DMZ
parameters.
If
you have a local client PC that cannot run an Internet application
properly from behind the NAT firewall, you can open the client up to
unrestricted two-way Internet access by defining a virtual DMZ Host.

3.9.4
ADSL type Setting
Go
to Advanced Setup ->ADSL to set different ADSL
connection.
If
you meet a ADSL connection problem, you can select a different ADSL
connection type to get more fast connection.

3.10.1
Static Routing
Go
to Advance Setup -> Routing ->Add to setup static route
features.
The
static routing function determines the path that router follows over
your network before and after it passes through your router. You can
use static routing to allow different IP domain users to access the
Internet through this device.

3.10.2
Dynamic Routing
Go
to Interface Setup -> Internet to select Dynamic Route as
you need.
The
dynamic routing feature of the router can be used to allow the
router to automatically adjust to physical changes in the network's
layout. The router uses the dynamic RIP protocol. It determines the
route that the network packets take based on the fewest number of
hops between the source and the destination. The RIP protocol
regularly broadcasts routing information to other routers on the
network.

3.10.3
Routing Table
Go
to Advance Management -> Routing to see the Routing Table.
The
Routing table allows you to see how many routings on your routing
table and interface information

3.11.1 System Status
Go to Status -> Device Info to see the router's
information. The System Status page shows the WAN, LAN and the router's firmware
version.

as the Router. A dynamic IP address may change every time your
computer connects to the network.
Encapsulation
The technique used by layered protocols in which a layer adds header
information to the protocol data unit (PDU) from the layer above. As

Internet address
An IP address is assigned in blocks of numbers to user organizations
accessing the Internet. These addresses are established by the
United States Department of Defense's Network Information Center.
Duplicate addresses can cause major problems on the network, but the
NIC trusts organizations to use individual addresses responsibly.

distant location.
RFC
Request for Comments - Refers to documents published by the Internet
Engineering Task Force (IETF) proposing standard protocols and
procedures for the Internet. RFCs can be found at www.ietf.org..
Route
The path that network traffic takes from its source to its
destination. The route a datagram may follow can include many
gateways and many physical networks.
In the Internet, each datagram
is routed separately.
Router
A system responsible for making decisions about which of several
paths network (or Internet) traffic will follow. To do this, it uses
a routing protocol to gain information about the network and
algorithms to choose the best route based on several criteria known
as "routing metrics".
routing table
Information stored within a router that contains network path and
status information. It is used to select the most appropriate route
to forward information along.
Routing Information Protocol
Routers periodically exchange information with one another so that
they can determine minimum distance paths between sources and
destinations.
SNMP

of choice for TCP/IP-based Internet.
SOCKET
(1) The Berkeley UNIX mechanism for creating a virtual connection
between processes.
(2) IBM term for software interfaces that allow two UNIX application
programs to talk via TCP/IP protocols.
Spanning-Tree Bridge Protocol (STP)
Spanning-Tree Bridge Protocol (STP) - Part of an IEEE standard. A
mechanism for detecting and preventing loops from occurring in a
multi-bridged environment.
When three or more LAN's segments are
connected via bridges, a loop can occur. Because a bridge forwards
all packets that are not recognized as being local, some packets can
circulate for long periods of time, eventually degrading system
performance. This algorithm ensures only one path connects any pair
of stations, selecting one bridge as the 'root' bridge, with the
highest priority one as identifier, from which all paths should
radiate.
Spoofing
A method of fooling network end stations into believing that keep
alive signals have come from and returned to the host. Polls are
received and returned locally at either end
Static IP Addresses
A static IP address is an IP address permanently assigned to
computer in a TCP/IP network. Static IP addresses are usually
assigned to networked devices that are consistently accessed by
multiple users, such as Server PCs, or printers. If you are using
your Router to share your cable or DSL Internet connection, contact your ISP to see if they have assigned your home a static IP address.
You will need that address during your Router's configuration.
Subnet
For routing purposes, IP networks can be divided into logical
subnets by using a subnet mask. Values below those of the mask are
valid addresses on the subnet.
TCP
Transmission Control Protocol - The major transport protocol in the
Internet suite of protocols provides reliable, connection-oriented
full-duplex streams.
TFTP
Trivial File Transfer Protocol - A simple file transfer protocol (a
simplified version of FTP) that is often used to boot diskless
workstations and other network devices such as routers over a
network (typically a LAN).
Telnet
The virtual terminal protocol in the Internet suite of protocols -
Allows users of one host to log into a remote host and act as normal
terminal users of that host.
Transparent bridging
So named because the intelligence necessary to make relaying
decisions exists in the bridge itself and is thus transparent to the
communicating workstations. It involves frame forwarding, learning
workstation addresses and ensuring no topology loops exist (in
conjunction with the Spanning-Tree algorithm).
UDP
User Datagram Protocol - A connectionless transport protocol that
runs on top of TCP/IP's IP. UDP, like TCP, uses IP for delivery;
however, unlike TCP, UDP provides for exchange of datagrams without
acknowledgments or guaranteed delivery. Best suited for small,
independent requests, such as requesting a MIB value from an SNMP
agent, in which first setting up a connection would take more time
than sending the data.
UNI signaling
User Network Interface signaling for ATM communications.
Virtual Connection (VC)
A link that seems and behaves like a dedicated point-to-point line
or a system that delivers packets in sequence, as happens on an
actual point-to-point network. In reality, the data is delivered
across a network via the most appropriate route. The sending and
receiving devices do not have to be aware of the options and the
route is chosen only when a message is sent. There is no
pre-arrangement, so each virtual connection exists only for the
duration of that one transmission.
WAN
Wide area network - A data communications network that spans any
distance and is usually provided by a public carrier (such as a
telephone company or service provider).
