ABOUT THE PRODUCT 1

The Megabit Modem® 410F and 420F use Asymmetric Digital Subscriber Line (ADSL) technology and Discrete MultiTone (DMT) line coding to provide a multi-megabit connection between the two modems using a single-pair telephone line. The Megabit Modem 410F and 420F are designed to be used together, one at each end of a circuit, with model 410F functioning as the ATU-C and model 420F functioning as the ATU-R.

420F

The Megabit Modem 410F and 420F support the full DMT rate of 7.552 Mbps downstream and 928 kbps upstream. The Megabit Modem 410F and 420F can be used in fixed rate mode or in rate adaptive mode. In rate adaptive mode, the modem sychnronizes at the maximum attainable data rate depending on distance and line condition.

The Megabit Modem 410F and 420F are easy to install and configure. To install each modem:

•connect a telephone cable from the modem to a wall phone jack that is wired for ADSL service

•connect a cable from the modem to a PC or an Ethernet hub for LAN service

•connect a power cable to a local power source

To configure each modem, launch a Web browser on your PC and access the Megabit Modem Configuration and Management Tool Web pages. Use the Web pages to configure the LAN, WAN, and ADSL connection; configure other system parameters; and monitor ADSL, LAN, WAN, and other networking functions. Or, you can access the modems through a PC connected to the modem RS-232 management port and then use the Megabit Modem Setup Menu to configure the modem parameters (these are a subset of the parameters that can be configured using the Megabit Modem Configuration and Management Tool Web pages).

LEDs on the modem front panel provide continual status at-a-glance for network and modem connections.
