| Abstract: | ADSL was described briefly.It is an antisymmetrical version of XDSL.ADSL Asymmetrical Digital Subscriber Line is a kind of internal communication method for the reconstruction of the existing phone networks,also the most popular communication technique.Finally the properties and techniques of ADSL were mentioned briefly,i.e.,it has very high transmission frequencies,can directly use the original double cables to surf the Internet and make phone calls at the same time,and can exclusively share the safety and security of the Internet.Comparison was made between ADSL and other common broadband switch-in techniques. |
