◈What is ADSL
ADSL (Asymmetric Digital Subscriber Line) is a technology for transmitting digital information
at a high bandwidth on existing phone lines to homes and businesses. Unlike regular dialup
phone service, ADSL provides continuously available, "always on" connection. ADSL is
asymmetric in that it uses most of the channel to transmit downstream to the user and only a
small part to receive information from the user. ADSL simultaneously accommodates analog
(voice) information on the same line. ADSL is generally offered at downstream data rates from
512 Kbps to about 8Mbps, upstream data rates up to 1Mbps.
ADSL was specifically designed to exploit the one-way nature of most multimedia
communication in which large amounts of information flow toward the user and only a small
amount of interactive control information is returned.

◈Safety Check
Before installing and using VisionNet 708, please the following topics must be checked first.
★Safety check related to the electricity, heat and water.
☞VisionNet 708 is Ethernet type ADSL modem, so you must connect VisionNet 708 to the
Ethernet Port in your PC.
☞VisionNet 708 must be located in safe space such as near non-grounded extension
cable, torn power cable and very close to the power outlet.
☞VisionNet 708 generates the heat when it is operating. It must not be exposed to heat
trap conditions.
☞It must not be used near water, like a bathtub, kitchen sink or in a wet basement.
These environments could damage VisionNet 708 or effect the performance of VisionNet
708.
◈The climate condition Check
