User Manual must provide user information: Instruction Manual Federal Communication Commission Interference Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help. FCC Caution: To assure continued compliance, (example – use only shielded interface cables when connecting to computer or peripheral devices). Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment.

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. 1.2 DEVICE INTRODUCTION 1 2 3 4 Figure 1  POWER indicator  LINK indicator  USB port  LINE port 1.3 PROTOCOL AND DRIVER 1.
