Introduction
About the 4000 Series Modems
The SpeedStream 4000 series external Asymmetric Digital Subscriber Line
(ADSL) modem provides a high-speed internet connectivity for a single
PC running Windows 98. The modem sends and receives data over
standard phone lines using Discrete Multi-tone (DMT) digital subscriber
line (DSL) transmission. The modem is connected to your PC through a
Universal Serial Bus (USB) port.
The modem requires a telephone line that supports ADSL. This service is
configured by your telephone company.
Data from the PC is transmitted and received using methods similar to that
used for analog modems. Data transmission over the DSL link is
performed by a combination of software on the PC and software and
hardware in the modem. Because a standard USB port is employed,
installation of an adapter card inside the PC is not necessary.
Installation Requirements
The following are the system requirements for installation:
• Windows 98 operating system already installed.
• 32 Mbytes RAM
• Pentium-class processor (100 Mhz or better) required.
• 1 Universal Serial Bus (USB) port
NOTE: You may need the Windows (95, 98 or NT) operating system
CD during installation. If you do not have this CD, contact your PC
vendor for details on where the Windows files are stored on your
machine.
