Chapter 1: Product Overview 
TP-LINK® TD-8840 External ADSL2+ ROUTER is the latest product designed and 
manufactured by TP-LINK Technologies Co., Ltd. With TP-LINK’s excellent circuit design 
and high quality production, we guarantee the ADSL2+ ROUTER’s high performance, 
great stability and easy to use. 
The TD-8840 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.   
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, support Auto-MDIX. 
The TD-8840 not only uses html (web mode through Ethernet port) to configure the 
ROUTER but also uses external utility software. You can download it from our website 
(http://www.tp-link.com).
