Product Description:

TD-8841 uses integrated ADSL2+ transceiver and a 256-MHz MIPS32 CPU.The AFE supports full-rate ADSL connectivity conforming to the ITU and ANSI specifications; MIPS32 CPU with MMU and 16-KB I-cache/8-KB D-cache is integrated into the device. In addition to the basic DMT physical layer functions, the ADSL PHY supports dual latency ADSL Framing (fast and interleaved) and the I.432 ATM Physical Layer.TD-8841 is a complete plug-and-play solution. With standard Ethernet interface, it can be directly connected to any 10M/100M Ethernet devices,supporting Auto MDI/MDIX.
The TD-8841 uses ADSL (Asymmetric Digital Subscriber Line) technology for Internet connection speeds of up to 455x faster than dial-up, while using a standard phone line. With a built-in 4-port switch, up to four network-ready computers or devices can simultaneously be connected to the TD-8841 for access to the Internet.
The device comes with a CD with an Easy Setup Assistant that helps you step by step to complete your Internet connection, wireless network settings and security configurations. This feature allows even novice users to setup the router products without sacrificing any key features, just play the AUTO-RUN CD bundled to have your network set up quickly & hassle-free.
TD-8841 not only use html (web mode through Ethernet port) to configure the MODEM but also use external utility software, too. With TP-LINKs excellent design of circuit and high quality production, we guarantee ADSL MODEM a high performance, very good stability and easy to use.

Product Features:

Access a high-speed DSL Internet connection Up to 24Mbps downstream speed Supports Annex M, which can double upstream data rates Connect your computer using Ethernet or USB Built-in switch connects four local PCs directly, and daisy-chain out to more hubs and switches as your network grows Built-in DHCP server Administer and Upgrade the Router Remotely over the Internet Easy Setup Assistant provides quick & hassle free installation

Description

The TP-LINK ADSL2+ Modem Router (TD-8841/TD8841B) is a 2-in-1 device that combines the functions of a DSL modem and 4-port 10/100 Ethernet router. It offers both Ethernet and USB ports for flexible connectivity. It supports the latest ADSL2/2+ standards to provide higher performance (up to 24Mbps downstream and 3.5Mbps upstream) and longer reach from your Internet Service Providers (ISP) Digital Subscriber Line Access Multiplexer (DSLAM). You can also create a wired network to share your high-speed Internet connection, documents, photos, music, videos, and printers. The TD-8841/TD-8841B includes a built-in QoS engine that helps prioritize Internet traffic to enable smooth Internet phone calls (VoIP) and lag-free online gaming. In addition, this device includes Dual Active Firewalls (Packet filtering and NAT) to help protect your network from potential attacks from across the Internet. Featuring high ADSL performance, various QoS policy, easy-touse, the TP-LINK TD-8841/TD-8841B is a good choice to access to the internet.
