TD-8840 uses integrated ADSL2+ transceiver & a MIPS32 CPU. The AFE supports full-rate ADSL connectivity conforming to the ITU & ANSI specifications; MIPS32 CPU with MMU & 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 & interleaved) & the I.432 ATM physical layer. TD-8840 is a complete plug-&-play solution. With standard Ethernet interface, it can be directly connected to any 10M/100M Ethernet devices, supporting 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.
