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.TD-8840 is a complete plug-and-play solution. With standard Ethernet interface it can be directly connected to any 10M/100M Ethernet devicessupporting Auto MDI/MDIX. The TD-8840 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-8840 for access to the Internet.
