Chapter 1. Introduction

Thank you for choosing the TD-8840 ADSL2+ Modem Router.

1.1

Product Overview

With the excellent circuit design and high quality production, we guarantee the ADSL2+ Modem

Router’s high performance, great stability and easy to use.

The TD-8840 uses integrated ADSL2+ transceiver. The AFE supports full-rate ADSL connectivity

conforming to the ITU and ANSI specifications.

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.

The TD-8840 is a complete plug-and-play solution. With standard Ethernet interface, it can be

directly connected to any 10M/100M Ethernet devices, and support Auto-MDIX.

The TD-8840 uses not only html (web mode through Ethernet port) but also external utility

software to configure the Router. You can download it from our website (http://www.tp-link.com).

1.2
