• G.994.1 (G.hs, Multimode)
• ITU-T G.992.3 (ADSL2 G.dmt.bis)
• ITU-T G.992.4 (ADSL2 G.lite.bis)
• ITU-T G.992.5 (ADSL2+; Annex A, I, J, L & M)
• Reach Extended ADSL (RE ADSL)
Quick Setup Wizard
Support Quick Setup Wizard Web GUI to configure this Wireless ADSL2+ router easily and quickly.
Multi-connection protocol support
• Multi Protocol over AAL5 (RFC1483 / 2684)
• Classical IP over ATM (RFC 1577)
• VC and LLC Multiplexing
• PPP over Ethernet (RFC 2516)

Network Address Translation (NAT)
Network Address Translation (NAT) allows the translation of an Internet protocol address used within one network (for
example a private IP address used in a local network) to a different IP address known within another network (for ex-
ample a public IP address used on the Internet).
Universal Plug and Play (UPnP)
Universal Plug and Play is a standard that uses Internet and Web protocols to enable devices such as PCs, peripher-
als, intelligent appliances, and wireless devices to be plugged into a network and automatically know about each other.
This protocol is used to enable simple and robust connectivity among stand-alone devices and PCs.

Dynamic DNS Support
With Dynamic DNS support, you can have a static hostname alias for a dynamic IP address, allowing the host to be
more easily accessible from various locations on the Internet. You must register for this service with a Dynamic DNS
client.
DHCP Support
DHCP (Dynamic Host Configuration Protocol) allows individual clients to obtain TCP/IP configuration at start-up from a
centralized DHCP server. The ADSL router has built-in DHCP server capability enabled by default. It can assign IP ad-
dresses, an IP default gateway and DNS servers to DHCP clients. It can also act as a surrogate DHCP server (DHCP
Relay) where it relays IP address assignment from the actual real DHCP server to the clients.
Device Management
• Web-based GUI Configuration / Management
• Command-line Interpreter (CLI)
• Telnet Remote Management
• Firmware upgrade via FTP / TFTP (Web-based GUI)
• Built-in Diagnostic tool and IP Ping
SNMP (Simple Network Management Protocol) Support
It’s an easy way to remote control the router via SNMP.
10/100M Auto-negotiation Fast Ethernet switch
This auto-negotiation feature allows the router to detect the speed of incoming transmissions and adjust appropriately
without manual intervention. It allows data transfer of either 10 Mbps or 100 Mbps in either half-duplex or full-duplex
mode depending on your Ethernet network.
Multiple PVC (Permanent Virtual Circuits) Support
• Support up to 8PVCs.
• Supports OAM F4/F5 loop-back, AIS and RDI OAM cells.

WIRELESS ROUTER ADSL
Steps to navigate the Web configuration from the Site Map are summarized below.
• Click on Quick Start to begin a wizard that helps to configure your router.
• Click on Interface Setup to configure Internet and LAN functions.
• Click on Advanced Setup to configure advanced features.
• Click on Access Management to manage Internet access options.

nostic tests on the router
• Click on Status to see router device information, system logs and performance statistics.
• Click on Help to see available help topics.
5. Interface Setup
The physical connections determine whether the router ports are local area network (LAN) ports or wide area network
(WAN) ports. There are two kinds of IP networks. The local, private kind is the LAN network; the global, public kind is
the WAN network. The following illustration shows the relationship between the router and the two different networks.
A LAN is a shared communication system to which many computers are attached. A LAN is generally limited to the im-
mediate area, usually the same building or floor of a building. A WAN is an outside connection to another network or
to the Internet.
Click an Interface Setup link to set ATM VC values, ISP Encapsulation, configure multi- connection settings, and LAN
configuration.
5.1 Internet
The Internet screen allows you to set up how your router connects to the Internet. If you already ran the Quick Start wiz-
ard, the information you provided to the wizard should be entered into the fields already. After you finish the changes,
click on the SAVE button to save your changes.

WIRELESS ROUTER ADSL
5.1.1 ATM VC & QoS
ATM settings are used to connect to your ISP. Your ISP provides VPI, VCI, settings to you. In this Device, you can totally
setup 8 PVCs on different encapsulations if you apply 8 different virtual circuits from your ISP. You need to activate the
VC to take effect. For PVCs management, you can use ATM QOS to setup each PVC traffic line’s priority. Virtual Circuit:
Select the VC number you want to setup. VPI: Virtual Path Identifier. The valid range for the VPI is 0 to 255. VCI: Virtual
Channel Identifier. The valid range for the VCI is 1 to 65635 (0 to 31 is reserved for local management of ATM traffic).
ATM QoS: Select the Quality of Service types for this Virtual Circuit. The ATM QoS types include CBR(Constant Bit Rate),
VBR(Variable Bit Rate) and UBR (Unspecified Bit Rate). These QoS types are all controlled by the parameters specified
below, including PCR, SCR, and MBS. PCR: Peak Cell Rate (PCR) is the maximum rate at which the sender can send
cells. This parameter may be lower (but not higher) than the maximum line speed. 1 ATM cell is 53 bytes (424 bits), so a
maximum speed of 832 Kbps gives a maximum PCR of 1962 cells/sec. This rate is not guaranteed because it is depen-
dent on the line speed. SCR: Sustained Cell Rate (SCR) is the mean cell rate of a bursty, on-off traffic source that can be
sent at the peak rate, and a parameter for burst-type traffic. SCR may not be greater than the PCR; the system default is
0 cells/sec. MBS: Maximum Burst Size (MBS) is the maximum number of cells that can be sent at the PCR.
After MBS is reached, cell rates fall below SCR until cell rate averages to the SCR again. At thistime, more cells (up to
the MBS) can be sent at the PCR again. CBR is for connections that support constant rates of data transfer. The only
parameter you need to worry about in CBR is PCR. UBR is for connections that have variable traffic. The only param-
eter you need to worry about in UBR is PCR.rtVBR is for connections that, while having variable traffic, require precise
timing between trafficsource and destination. PCR, SCR and MBS must all be set for rtVBR. nrtVBR is for connections
that have variable traffic, do not require precise timing, but still require a set bandwidth availability. PCR, SCR and MBS
must all be set for nrtVBR.
5.1.2 Encapsulation
Select the encapsulation protocol your ISP uses. The following section will vary depending on which encapsulation
protocol you select.

mand is dependent on the traffic. If there is no traffic (or Idle) for a pre-specified period of time, the connection will tear
down automatically. And once there is traffic send or receive, the connection will be automatically on.
IP Address: For PPPoE/PPPoA connection, you need to specify the public IP address for this ADSL Router. The IP ad-
dress can be either dynamically (via DHCP) or given IP address provide by your ISP. For Static IP, you need to specify
the IP address, Subnet Mask and Gateway IP address.

the ADSL Router will periodically send routing information and accept routing information then incorporate into routing
table. IN only means the ADSL router will only accept but will not send RIP packet. OUT only means the ADSL router will
only sent but will not accept RIP packet.
[Multicast]
IGMP (Internet Group Multicast Protocol): It is a session-layer protocol used to establish membership in a multicast
group. The ADSL supports both IGMP version IGMP-v1 & IGMP-v2. Select None to disable it.
