ADSL FAQs and usage skills

"Broadband household" and "broadband Internet access" are selling points for some real estate agents to promote real estate. Some branches of China Telecom recently launched the ADSL Broadband technology, which has become the focus of attention. In the Beijing region, you only need 300 yuan to access the Internet using ADSL. This is indeed very attractive to us. However, before using ADSL, you 'd better study it first and thoroughly, which will be more beneficial for you to use ADSL.

I. Introduction to ADSL

ADSL is the abbreviation of asypolicric Digital Subscriber Loop Asymmetric Digital user Loop, 8 Mbits/s download rate and 1 Mbits/s upload rate can be provided on the general telephone network based on the local line conditions. It is also called the asymmetric digital user loop because its download and upload rates are different. However, it is still wrong if we call it broadband, because according to the definition of the international electrical organization, only when the download and upload rates reach 10 Mbits/s can it be called broadband, ADSL obviously does not meet this requirement. However, even if the download speed is 8 Mbits/s and the upload speed is 1 Mbits/s, our online on-demand movies, software downloads, and online chats will feel fast (hundreds of times more than normal dial-up Modem )! More importantly, using ADSL to access the Internet does not interfere with each other, and there is no need to make phone calls to access the Internet. Of course, the cost of ADSL is also very low (1). You do not need to pay the telephone fee for dial-up Internet access when using ADSL, saving you a sum of money.

USB Installation Without disassembling, welcomed by many friends, RJ-45 port does not need to install the driver, but to use with the ethernet card. At this time, we must purchase a network card. Of course, the NIC must have a twisted pair to connect to the ADSL Modem.

It is worth noting that do not select the ADSL Modem of the USB interface, because the transmission rate of USB 1.1 is very low, it will affect the network speed. We recommend that you use the ADSL Modem of the RJ-45 port.
