ADSL（AsymmetricalDigitalSubscriberLoop）：对错对称数字用户线的缩写，它使用抢先的线路调制技术，理论上可以在一对电话线上支持上行最高到1Mbps、下行最高到8Mbps的传输速率，其有效传输间隔在0－5公里设计以内

(ADSL (AsymmetricalDigitalSubscriberLoop): The abbreviation of right and wrong Symmetrical Digital Subscriber Line, it uses the preemptive line modulation technology, in theory, it can support the transmission rate of up to 1Mbps in uplink and up to 8Mbps in downlink on a pair of telephone lines. The effective transmission interval is 0-5 kilometers within the design)
