ADSL MODEM USER MANUAL - 4 - 1. OVERVIEW 1.1 ABOUT ADSL ADSL MODEM is a broadband Internet access device，which utilizes the high frequency segment of the phone line to transmit high-speed data without interfering with the voice transmission. The frequency of ADSL signal is higher than that of voice, so voice and ADSL signal can coexist in one line by using a splitter to insulate each from the other. ADSL data transfer on the asymmetry way. The upload speed is up to 1Mbps and download speed is up to 8Mbps. It is an ideal device for broadband access. 1.2 DEVICE INTRODUCTION Figure 1.1 Interface introduction: ① Power Interface: 5.2V DC, 1000mA. ② Power switch: To turn on or off the power. ③ Reset Key: Reset default configuration. ④ Ethernet Interface: To be connected to a PC or a HUB by a CAT 5 twisted parallel cable. A straight-through network cable should be used when it is connected to a PC network card and a crossover cable should be used for UP LINK interface of HUB. ⑤ Line Interface: To be connected to a telephone. 1 OVERVIEW
