2.1 Overview

The Portable USB Modem incorporates V.90 technology, which enables Internet connections at data rates up to 56 kbps* over standard telephone lines. V.90 technology sends data downstream from the Internet to your computer at these speeds because data on the telephone network typically is converted from digital to analog only once before it reaches your modem. Upstream transmissions, and transmissions between client modems, are limited to data rates of 33.6 kbps, as are downstream transmissions that are converted more than once on the telephone network.

The modem is Plug-and-Play in Windows® 2000, Windows Me, and Windows 98 operating systems with interactive automatic dialing and command mode configuration. In standard mode, you can store up to two command lines or telephone numbers of up to 40 characters each in the modem’s nonvolatile memory. The modem pulse- or tone-dials, and recognizes dial tones and busy signals for reliable call-progress detection. The modem can detect AT&T® calling card tones. It also has Caller ID, remote configuration, and incorporates self- resetting lightning protection. The modem is FCC-registered for connection without notification to the telephone company.

This full-duplex, intelligent modem also has V.42 error correction, V.42bis data compression, and V.17 (14,400 bps), Class 1 and 2, Group 3 fax capabilities.

The modem operates with the Global Wizard program. Telephone company technical requirements differ from country to country. In the Global Wizard program, simply specify the country in which you will operate, selecting from a pull-down menu. Global Wizard does the rest, automatically setting up the correct operating parameters for your modem to operate in your country.

The Flash Wizard utility lets you update the modem’s firmware.

*Although K56flex technology is capable of downloads of up to 56 kbps, FCC regulations currently restrict ISP modems to downloads of 53 kbps.
