MINIMODEM USB

2. Introduction

2.1 Description

The MiniModem USB incorporates V.90 technology, which enables Internet connections at data rates up to 56 kbps over standard telephone lines. (Although V.90 technology is capable of downloads of up to 56 kbps, FCC regulations currently restrict ISP modems to downloads of 53 kbps.)

V.90 technology can send 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 MiniModem USB is a full-duplex intelligent modem with V.42 error correction, V.42bis data compression, and V.17 (14,400 bps), Class 1 and 2, Group 3 fax capabilities.

MINIMODEM USB

2.2 Universal Serial Bus (USB)

Universal Serial Bus (USB), defined by a consortium of industry leaders, permits connection of multiple lowspeed and medium speed computer peripheral devices such as telephones, modems, printers, keyboards, mice, and scanners, all from a single personal computer port. The specification, based on an open architecture, is quickly becoming a standard feature in new desktop and notebook computers.

MINIMODEM USB

• Avoid using a telephone (other than a cordless type) during an electrical storm; there may be a remote risk of electrical shock from lightning.

• Do not use a telephone in the vicinity of a gas leak.

3.4 Step 1: Assemble the Modem

The only assembly required is to mount the feet on the bottom of the modem. Simply peel the four self-adhesive plastic feet off the backing strip and press them into the recesses on the bottom of the modem. Alternately, or additionally, you can use the included self-adhesive hook-and-loop patches to mount the modem on a vertical surface or to keep it from being dislodged on a horizontal surface. If you use the hook-and-loop patches, we recommend that you mount them where they will not obscure the labels or screws on the bottom of the modem.
