DB108-WL wireless ADSL MODEM manual 1. OVERVIEW 1.1 ABOUT ADSL An ADSL MODEM is a broadband Internet access device which utilizes the high frequency segment of the phone line to transmit high-speed data without affecting the voice transmission. The frequency of the 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 adapts the asymmetry model.
DB108-WL wireless ADSL MODEM manual Data Indicator (green): Flash means the Modem is transmitting or receiving data. Power Interface 11VDC 700mA. Ethernet Interface Using CAT 5 twisted parallel cable to connect with PC or HUB. When connecting with PC network card, use direct network cable; connect with UP LINK interface of HUB by the crossover network cable. Usb Interface For Modem connection on program upgrade or alternative internet access. Line Interface Connect to telephone.
