Chapter 1.Introduction

Thank you for choosing the TD-W8901N 150Mbps Wireless N ADSL2+ Modem Router.

1.1Product Overview

The device is designed to provide a simple and cost-effective ADSL Internet connection for a private Ethernet or IEEE 802.11n/ IEEE 802.11g/ IEEE 802.11b wireless network.

The TD-W8901N connects to an Ethernet LAN or computers via standard Ethernet ports. The ADSL connection is made using ordinary telephone line with standard connectors. Multiple workstations can be networked and connected to the Internet using a single Wide Area Network (WAN) interface and single global IP address. The advanced security enhancements, IP/MAC Filter, Application Filter and URL Filter can help to protect your network from potentially devastating intrusions by malicious agents from the outside of your network.

Quick Start of the Web-based Utility is supplied and friendly help messages are provided for the configuration. Network and Router management is done through the Web-based Utility which can be accessed through local Ethernet using any web browser.

The TD-W8901N supports full-rate ADSL2+ connectivity conforming to the ITU and ANSI specifications. In addition to the basic DMT physical layer functions, the ADSL2+ PHY supports dual latency ADSL2+ framing (fast and interleaved) and the I.432 ATM Physical Layer.

In the most attentive wireless security, the modem router provides multiple protection measures. It can be set to turn off the wireless network name (SSID) broadcast so that only stations that have the SSID can be connected. The modem router provides wireless LAN 64/128-bit WEP encryption security, WPA-PSK/WPA2-PSK authentication, as well as TKIP/AES encryption security.

ATM VC: ATM settings are used to connect to your ISP. Your ISP provides VPI (Virtual Path Identifier), VCI (Virtual Channel Identifier) settings to you. In this Device, you can totally setup 8 VCs on different encapsulations, if you apply 8 different virtual circuits from your ISP. You

18

TD-W8901N 150Mbps Wireless N ADSL2+ Modem Router User Guide

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, PVC0~PVC7.

PVCs Summary: Click the button, and you can view the summary information about the PVCs.

Status: If you want to use a designed VC, you should activate it.

VPI: Identifies the virtual path between endpoints in an ATM network. The valid range is from 0 to 255. Please input the value provided by your ISP.

VCI: Identifies the virtual channel endpoints in an ATM network. The valid range is from 32 to 65535 (1 to 31 is reserved for well-known protocols). Please input the value provided by your ISP.

QoS: Select the Quality of Service types for this Virtual Circuit, including CBR (Constant Bit Rate), UBR (Unspecified Bit Rate) and VBR (Variable Bit Rate). These QoS types are all controlled by the parameters specified below, including PCR (Peak Cell Rate), SCR (Sustained Cell Rate) and MBS (Maximum Burst Size), please configure them according to your needs.

4.3.1.1 IPv4

There are two IP versions: IPv4 and IPv6. If you select IPv4 as IP version, please follow the configuration below to configure the parameters for WAN ports.

Encapsulation: There are four connection types: Dynamic IP Address, Static IP Address, PPPoA/PPPoE and Bridge Mode. Please choose the designed type that you want to use. After that, you should follow the configuration below to proceed.

1)Dynamic IP Address

Select this option if your ISP provides you an IP address automatically. This option is typically used for Cable services. Please enter the Dynamic IP information accordingly.

19

TD-W8901N 150Mbps Wireless N ADSL2+ Modem Router User Guide

Figure 4-7

Encapsulation: Select the encapsulation mode for the Dynamic IP Address, you can leave it default.

Bridge Interface: Activate the option, the modem router can also work in Bridge mode.

Default Route: If enable this function, the current PVC will be considered as the default gateway to Internet from this device.

TCP MTU Option: Enter the TCP MTU as your desire. The default value is 1500.

IPv4 Address: If you select IPv4 as IP version, you should configure the following.

NAT: Select this option to Enable/Disable the NAT (Network Address Translation) function for this VC. The NAT function can be activated or deactivated per PVC basis.

Dynamic Route: Select this option to specify the RIP (Routing Information protocol) version for WAN interface, including RIP1, RIP2-B and RIP2-M. RIP2-B and RIP2-M are both sent in RIP2 format, the difference is that RIP2-M using Multicast, while RIP2-B using Broadcast format.

Direction: Select this option to specify the RIP direction. None is for disabling the RIP function. Both means the ADSL modem router will periodically send routing information and accept routing information, and then incorporate them into routing table. IN only means the ADSL modem router will only accept but will not send RIP packet. OUT only means the ADSL modem router will only send but will not accept RIP packet.

Multicast: Select IGMP version, or disable the function. IGMP (Internet Group Multicast Protocol) is a session-layer protocol used to establish membership in a multicast group. The ADSL ATU-R supports IGMP version 1 (IGMP v1), IGMP version 2 (IGMP v2) and IGMP version 3 (IGMP v3). Select “Disabled” to disable it.

2)Static IP Address
