ADSL is an affordable broadband access solution. Currently, it is billed in monthly subscription mode. If a user uses an account to access the Internet, it will be a bit uneconomical. How can one ADSL user access the Internet? The following are some experiences.　　 Sharing principle　　 In view of the current mainstream Ethernet interfaces, the external ADSL Modem has built-in routers and routing functions, and also has a large-capacity ROM chip (includi

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, however, after using a networking device, you can implement an ADSL line to support Internet access shared by multiple computers. Generally, devices that implement the shared networking of ADSL include ADSL Modem, Broadband Router, an

wireless router, we have to do the physical connection operations related to the wireless router: First of all, the ADSL modem device is connected to the WAN port of the wireless router, and then the common twisted pair connects the LAN port of the wireless router with the normal workstation. After completing the physical connection operation, we go to the Windows system interface of the normal workstation and open the system's TCP/IP property Setti

Shanghai Bell Company's Cablelink Cable modem system provides high-speed asymmetric data communication services to users through the fiber coaxial hybrid network. The asymmetry of its connections requires high-speed communications in one direction, such as network browsing, Internet file transfer, and ideally in the opposite direction with a lower-rate delivery service. The TDMA access method used in Cablelink 2000 system can make the system more flex

China's broadband routers are developing very fast and their technology is also very mature. Many people may not know the application of broadband routers in the access technology. It doesn't matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. 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

is a dual-CPU architecture, as shown in figure 1. The main processor runs an open operating system and controls the entire system from the DBB (Digital Baseband Chip) where the processor is a wireless modem ), it mainly implements A/D conversion of voice signals, D/A conversion, encoding and decoding of digital voice signals, channel encoding and decoding, and timing control of wireless modem. Master-slav

ADSL is today a relatively affordable broadband access scheme, its billing is currently generally used in the way of the monthly. If a user uses an account to surf the internet, it is bound to be a bit not cost-effective, how to achieve an ADSL multiple users online? The following is an exchange of experience. Sharing principle In view of the current market mainstream Ethernet interface External ADSL modem has a built-in router, with routing functions

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

From: http://topic.csdn.net/t/20030528/15/1845691.html Using GPRS modem to access the Internet, the current implementation method is to use PPP as a transit, the GPRS transmission layer is like this:--------IP/X.25--------Sndcp--------LLC----------------RLC----------------Mac----------------RF----------------Ms is on the left and BS is on the right. For Ms, IP support can be provided, either in me, Ta, or te, as long as there is an interface. However

Before talking about this, we will first introduce another concept, DCE (Data Communication Equipment) speed. It refers to the transmission speed between two modem devices, that is, between telephone lines. We call 56k the speed. DTE (data terminal equipment) refers to the transmission speed from the local computer to the modem. If the telephone line transmission rate (DCE speed) is 56000bps, after receivin

the analog signal received by the modem to a digital signal, which is the modulation and demodulation of the signal.The device that implements the modulation and reconciliation task is called a modem ). When band transmission is adopted, both parties connect to a modem to transmit digital signals on analog signals (carriers. Therefore, this transmission method i

ADSL Broadband Access networks are still commonly used. So I have studied the troubleshooting methods for common faults in ADSL Broadband Access networks. I would like to share with you here, hoping to help you. With the rapid development of the Internet, the ADSL Broadband Access Network is rapidly developing. The advantage of low price has become the first choice for network access for individual users. As you know, when the ADSL Modem receives the
