WINADSL例子



ADSL （Asymmetric Digital Subscriber Line ，非对称数字用户环路）是一种新的数据传输方式。它因为上行和下行带宽不对称，因此称为非对称数字用户线环路。它采用频分复用技术把普通的电话线分成了电话、上行和下行三个相对独立的信道，从而避免了相互之间的干扰。即使边打电话边上网，也不会发生上网速率和通话质量下降的情况。通常ADSL在不影响正常电话通信的情况下可以提供最高3.5Mbps的上行速度和最高24Mbps的下行速度。-ADSL (Asymmetric Digital Subscriber Line, Asymmetric Digital Subscriber Line) is a new data transmission. It is asymmetric because the upstream and downstream bandwidth, so called asymmetric digital subscriber line loop. It uses frequency division multiplexing to ordinary telephone lines into the phone, three separate uplink and downlink channels, thus avoiding mutual interference. Even talking on the phone online, it will not happen speed Internet access and voice quality decline. Usually does not affect normal ADSL in the case of telephone communications can provide up to 3.5Mbps and uplink speeds up to 24Mbps downstream speed.
