China's ADSL access technology has developed very rapidly. So I have studied the features and applications of the ADSL access technology. I would like to share with you here, hoping it will be useful to you. The maximum downlink rate of ADSL2 is 12 Mb/s due to improved frame structure and optimized RS encoding. Because ADSL2 + uses a wider spectrum, there are more than 512 sub-carriers). When the distance i

As a broadband network for implementing high-speed Internet, there are currently some practical access methods, such as ADSL, CATV, fiber + LAN Ethernet, and WiMAX wireless access networks, but today we will talk about power line online PLC) and compare it with ADSL to understand it. PLC is a new "last mile" SOLUTION Similar to other broadband access methods, PLC is essentially a solution for local telecom

Hacker attacks and the spread of viruses have become a major "characteristic" of the Internet. In addition, the computers of ADSL Internet users have a public IP address when accessing the Internet. ADSL Internet computers are highly risky. It is undeniable that some security components are integrated into routers, and their functions are still too simple. More importantly, there are very few

user's APRU value. Ii. Bandwidth bottleneck of IPTV applications IPTV can use existing copper resources to transmit interactive TV programs. At present, most broadband users in China use ADSL as the access method. However, using the ADSL Access Mode to watch IPTV faces the following two challenges: 1. distance problem: the user line ring resistance suitable for activating

The 1. Network adapter is bound too many protocols. Slow Internet access is common among local area network users because the network adapter is bound too many protocols. If a lot of protocols are bound on the network card, when the data passes through the network card, the computer spends a lot of time to determine which protocol the data uses to transmit, then the user will feel the Internet is slow. The solution is: let a network card only run PPPoE protocol to connect

ADSL is called asymmetric Digital subscriber line. ADSL is called asymmetric because its two duplex channels are used to transmit data to the user, only a small portion of the bandwidth used to send back to the user's information. ADSL on a pair of copper wire support upload rate 640kbps~1mbps, 1mbps~8mbps rate, effective transmission distance within the 3km~5km

Everyone should know, now a lot of cats with automatic dialing function, we can put the account number in the ADSL cat dial-up software, so that each time the computer starts the ADSL cat can automatically dial, an open computer can be online. The above work is done through the following steps: One: Enter the cat's default address in the browser, such as: http://192.168.1.1, this time will pop up a dialog

ADSL Dial off line There are three workstations in the office, the use of shared ADSL routing access to achieve simultaneous internet purposes, each workstation's internet speed is good. A few days ago, a colleague in the office said recently do not know how, every time after the successful dial is not long, the network connection will be off the line failure, even if there is no drop line failure, ie bro

ADSL Access networks are quite common. So I have studied some common problems and users' questions about ADSL Access networks. I would like to share them with you here, hoping they will be useful to you. Many users have reported that the download rate of ADSL does not reach the nominal 512 KB. After the brain accesses the network through

During the installation and use of the ADSL Access optimization method, we have previously introduced the features of the ADSL Access optimization function. Today, we have taken it out again to better understand the sources of the ADSL Access optimization, and the internal connection between ADSL Access optimization an

The functions of the ADSL Broadband Router are very powerful, and its performance is also very good. Next we will mainly explain how the ADSL Broadband Router achieves Internet sharing among multiple computers. At present, ADSL permeate every corner of our lives, whether it is enterprises, Internet cafes, or home users using
