Chapter 1. Introduction
Thank you for choosing the TD854W 150Mbps Wireless N ADSL2+ Modem Router.
1.1 Product 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 TD854W 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, MAC Filter, IP/Port
Filter, URL Filter and ACL can help to protect your network from potentially devastating intrusions
by malicious agents from the outside of your network.
Wizard 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.
ADSL
The TD854W 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.
Wireless
In the most attentive wireless security, the 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 Router provides wireless LAN 64/128-bit WEP encryption security,
WPA-PSK/WPA2-PSK authentication, as well as TKIP/AES encryption security.
1.2 Main Features
 Wireless AP, Router, 4 Port Switch and Firewall
 Support ITU-T G.992.1 (G.dmt), ANSI T1.413, G.992.2 (G.Lite), ADSL2 and ADSL2+
