1. About ADSL

ADSL (Asymmetric Digital Subscriber Line) is a technology that allows high-speed
data to be transmitted over existing copper telephone lines. 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 supports upload transmission speed
up to 1Mbps and download speed up to 8 Mbps. Its data transfer rate adapts to the quality
of telephone line and its distance. ADSL modem is an ideal device for broadband access.
