1. OVERVIEW
1.1 ABOUT ADSL
An ADSL MODEM is a broadband access device, which utilizes the high frequency segment of a phone
line to transmit high-speed data without interfering with the voice transmission. The frequency of the ADSL
signal is higher than that of voice, so the voice and ADSL signal can coexist in one line by using a Splitter to
insulate the two. ADSL data transfer adapts asymmetry model. It has an upstream maximum transmission rate
of 1 Mbps and downstream maximum transmission rates of 8 Mbps. This ability makes ADSL an ideal device
for broadband access.

3Plug the other end of the USB cable as shown here to the ADSL USB port as shown by
interface in Figure 1 Section 1.
After you complete the above steps, your PC will indicate, “Found new hardware and installing
driver”. Please refer to section 2.3 for more details.

Driver under LAN folder is for 1483 bridge connecting, 1483 routing and 1577 private line.
NOTEPlease close all running programs before installing the driver. Windows®98 installation CD will
be required for driver installation.
The following shows the steps for WAN driver installation. LAN driver installation is similar to this.
1. Once the new hardware is detected as shown in the dialog box below, Click “Next” button. As shown figure
