Small Business office network using ADSL sharing internet economic benefits. Upgrading the ADSL modem is a highly technical work. If you are careless, you may be able to cause the device to not work properly, so please think twice before you do it! The common practice is to use a hub with Proxy server software, using a computer as a proxy server, other computers through this agent sharing ADSL Internet. But this way of sharing the Internet, with the

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 p

test, if still ineffective, the cause of this problem is generally hardware-led; 4 If the connection is normal, the network appears to be restricted state, then confirm that other computers are connected to normal, such as other computers are also unable to connect, this problem to determine the cause of the network environment, the problem does not appear in computer products, please check the network problem; 5 if the elimination of network problems, please confirm that the

three-band standard has defined either the QAM or DMT modulation methods, as a result, there has been a long debate over the two standards, facing the choice of the two modulation methods. The QAM method is simple and easy to develop, and the DMT method is more complex. Although with the development of ADSL2 + technology, many people have doubts about the application prospects of VDSL technology, on the other hand, VDSL technology has unparalleled advantages in bidirectional symmetry and high b

than 250 M away from the end user, with a target bandwidth of 500-1000 M per household. As you are closer to the user, you can get a relatively higher bandwidth, and G. fast will be used as a gigabit access solution comparable to FTTH. Unlike previous technologies, G. fast introduces user-defined concepts at the initial stage of standard design. Traditional copper wire access technologies, both ADSL2 and VDSL2, are fixed upstream and downstream bandw

optimize the broadband access network according to the "FTTx + ADSL2 +/VDSL2" construction model. They believe that the "light-to-copper retreat" is not only time-ordered, but also space-oriented. In the early days, PON technology can target some high-end users with high bandwidth business needs, or, as a supplement to xDSL, xDSL is provided in areas with intensive SMEs to make up for the shortcomings of xDSL in these fields. After a step-by-step con

business broadband network, the broadband access network is undergoing profound changes. On the one hand, xDSL technology gradually from adsladsl2adsl2+ to provide a higher bandwidth VDSL2 upgrades, which also requires vdsl2dslam closer to the user side. With the increase of the number of VDSL2 Zhi, the requirement of efficient aggregation of large quantities of dslam is put forward. On the other hand, fib

whether the problem is resolved. If the problem persists, continue until the fault disappears. Layered Network diagnosis technology Physical Layer faults mainly occur when the physical connection mode of the device is correct, the connection cable is correct, and the configurations and operations of devices such as Modem, CSU, and DSU are correct. The best way to determine whether the physical connection of a vro port is intact is to use the show int

Check the Ethernet port of the host to the peer router.Use the telnet command to remotely log on to the peer vro, and check the LAN connection of the peer by checking the Ethernet port from the local host to the local vro.5.

Small-sized enterprise office networks use ADSL shared Internet access, which is cost-effective. Upgrading ADSL Modem is a highly technical task. If you are not careful, the device may not work properly. Therefore, please think twice before you start! The general practice is to use the hub with the proxy server software, using a computer as the proxy server, other computers share the Internet through this proxy. Without such Internet sharing, there ha

The internet will often encounter a drop in the line. The Web page can not open, download interrupted, or online video, audio streaming interruption, QQ off the line, the game out of line phenomenon. We might as well assume that the landlord is using ADSL Internet. In fact, other ways of surfing the internet often dropped the reason and the following reasons are roughly the same. Now let's analyze the reason for ADSL off line. 3lian Material One, line problem first check the home line, to se

Failure phenomenon: XP system, the normal dialing, IP address has been allocated, but is not online, QQ, browsing the web is not good, reload the cat's drive, with the dial-up software is not, the cat line and power indicators are bright, not hot, restart the computer and cat useless, can ping with their own IP, recently appeared many times, Strange is how not to do , no matter how well he's done for a while, ask for help. Solution: 1. Prompted that the search page could not be opened. This t

Troubleshooting Router Interface Serial Port Trouble Shooting Serial port connectivity problems, in order to eliminate the serial port fault, usually from show interface serial command, analysis of its screen output report content, to find out where the problem lies. The beginning of the serial port report provides the state of the interface and the status of the line protocol. There are several possible combinations of interfaces and line protocols: 1. Serial port operation, line protocol ope

When using the frequency band transmission, each side of the communication is connected to a modem, and the digital signal is sent to

Broadband routers in China are developing very rapidly. Here we mainly introduce the access to ADSL Modem with routing functions, including the access to ADSL Modem + Broadband Router. At present, ADSL permeate every corner of our lives, whether it is enterprises, Internet cafes, or home users using ADSL to access the Internet, usually, an ADSL line can only support one computer to access the Internet, howe

access includes a computer, adsl modem, a separator, a nic, and an ADSL telephone line. The correct connection method is to connect the telephone line to the separator, connect the Phone to the Phone interface of the separator, and connect the ADSL Modem to the Modem interface. Connect the computer network card to the ADSL M
