is used to transmit a 10 Mbit/s LAN Service, the carrier must allocate an e334mbit/s bandwidth to it. If the STN is used, a 10 Mb/sLAN service and a 6 Mb/sMPEG2 video service can be implemented on the same E3 line, other services can also be transmitted on the same E3 line until 34 Mb/s is full. 5) The STN provides the fractional ATM network and digital user line access multiplexing (LSIHM) for the broadband access network) two Application Methods. BeforeUsers can reduce the cost of the ATM swi

There are many things worth learning about broadband access servers. Here we mainly introduce the functions of broadband access servers in the whole network access business. The broadband access server is mainly used to meet the current requirements of various DSL access applications, especially the application requirements of ADSL access networks. Currently, ADSL access is based on the ATM network platform, and is an ATM. However, the current network architecture is mostly pure IP and large. At

, integrating the IP firewall function with SSG has a good prospect for practical application. Supplement of networking applications for Broadband Access Servers As mentioned earlier, the Broadband Access Server is mainly used to meet the current requirements of various DSL access applications, especially ADSL access. Currently, ADSL access is based on the ATM network platform, and is an ATM. However, the current network architecture is mostly pure IP and large. At the same time, the debate on A

Start> Run next time, enter the "winipcfg" command in the run column, and then click OK. In Windows/XP, click "Start> Run" on the computer, enter the "cmd" command in "open", and press Enter, in the Command Prompt window that appears, enter "ipconfig/all" and press Enter. You can see that the gateway address of the broadband wireless cat is enabled by default when the DHCP server is enabled for the broadband wireless cat ). On the WEB configuration page of the broadband wireless cat, you must f

. Introduce MPLS to the access layer With the advancement of FTTx, on the one hand, the traditional leased line service is also faced with the dilemma of the ATM switch return. A large number of leased line services need to be accessed with high quality and quality. If a single access is built to carry this service, it will bring a huge burden to operators. On the other hand, the traditional DSLAM mode service configuration mainly uses VLAN configurat

difference between the gradual disappearance of IP streaming media can easily be a large application in man, so currently provides 10/100BASET,GBE, 10GbE network interface has become the video server to keep up with the trend of the Times performance. Currently, there are many streaming media services that are based on a CATV network or a HFC network, so many servers provide Dvb-asi or qam64/256 interfaces for such an access network. In addition, for ADSL access mode, some servers can provide

advantages, and each has its own shortcomings.1 Current main access network technologyIn many scenarios, ADSL technology using the original telephone lines, without modification can transmit high-speed data (downlink 12.5-8mb/s, uplink 16-640kb/s), the local Dslam after reuse and ATM network adaptation, is a traditional carrier development network special fancy of the program, But ADSL provides the bandwidth is not too high, the actual use of the ope

three. Dial-up AddressVpnSet1.Networking RequirementsThis example will The combination of IPSec and ADSL is a typical case which is widely used in the present practice. (1) Router B is directly connected to the DSLAM Access terminal of the public network via ADSL , as the client side of PPPoE . Routerb The IP address that is dynamically obtained from the ISP is the private network address. (2) the head office LAN is connected to the ATM network via Ro

according to the tag information, such as reuse, oversubscribe of the business) and separate management and control of each data stream. A gsmp connection can carry a large amount of Ethernet user data, and store network data and data of Packet Ring services. In addition, each service can have independent traffic and QoS parameters, over-order level, and fault protection and recovery mechanisms. At present, GSMP is mainly applied in the following aspects: Aggregation and transmission of multipl

networks using the ADSL access mode. There is no essential difference between the ADSL service differentiation method and the IP service differentiation method. It requires scalable, high-capacity, and smart DSLAM to provide IP Forwarding functions, support various QoS mechanisms and user management functions required by DiffServ, and can quickly implement the above processing. However, the problem lies in another form of broadband access network-Eth

network are not smooth, and the DNS server is wrong. As shown in figure 2, this is the diagnosis result when I unplug the ADSL power supply. Figure 2 ADSL Fault Detection We have determined that there is no problem with the NIC and the driver, but the ADSL Modem, DSLAM, and BRAS may have faults. By selecting "detailed diagnosis information ", we can also further understand the Fault Cause 3). This is a summary of the fault. The "cause" mentioned her

the user end to the DSLAM terminal is not faulty. If the indicator light is not on, the line is faulty, it must be handled by the Telecommunications Department on site.3. Does the user change the IP address?Each user's PC has its fixed IP address. If the user changes its IP address, the Telecommunications Department can provide the IP address of its PC and change the IP address back.4. Check whether the user Nic and network cable are normalAfter the

the egress bandwidth, making the user's network speed unstable. Advantages of ADSL: ADSL Internet access is the most widely used broadband access method in the world. It has mature technologies, high transmission rates, and stable lines. ADSL uses an existing pair of telephone copper wires to load and reuse devices on the original telephone lines. It makes full use of existing copper wire resources to provide 8 Mbps downstream bandwidth at 640kbps on a pair of twisted wires, generally, househol

of the user is changed, the disconnection has not been improved. It seems that the real cause of the fault is not the line quality. After the broadband maintenance personnel of telecom operators change the user to the first-generation ADSL mode, the phenomenon of bandwidth interruption disappears. Does the user's broadband Modem not support the ADSL2 + mode? Broadband mode in broadband Modem The user's bandwidth is restored to the ADSL2 + mode, and the disconnection failure is resumed. Enter t

this case, you need to upgrade the modem software before using the built-in routing function. (1) Figure 1 1. Key parameters:According to the instructions provided by the merchants, enabling the adsl modem routing function is not difficult, but there are several key data that need to be well grasped. 1), VPI (Virtual Path Identifier), VCI (Virtual Channel Identifier ). VCI and VPI are the marks for DSLAM to identify the AD

. It is called an asymmetric digital user line loop because of asymmetry between upstream and downstream bandwidth. It uses the frequency division multiplexing technology to divide common telephone lines into three relatively independent channels: telephone, uplink and downlink, thus avoiding mutual interference. Even if you use a phone call to access the Internet, the Internet access rate and communication quality will not decrease. Generally, ADSL can provide up to 3.5Mbps uplink speed and up

complete the installation. You do not need to manually add the protocol driver on the network properties page or set any parameters. after starting the adsldial, you only need to enter the user name and password, you can easily go online. Figure 1 shows the main interface of the adsl. Unfortunately, the link content in the red box below the interface is somewhat redundant. Both the "Broadband dial King" and "Super network management" options actually point to the same webpage, this is hard to u

one hand, it can make full use of private network addresses to relieve the pressure on public network IP address resources. On the other hand, NAT achieves internal network security through one-way forwarding of IP traffic. Networking applications of Broadband Access Servers The broadband access server is mainly used to meet the current requirements of various DSL access applications, especially the application requirements of ADSL access. Currently, ADSL access is based on the ATM network plat

In terms of IP Internet, telecom equipment vendors only use cisco at the core, and Cisco is very embarrassed now. junipor or Huawei is also hitting the market in other countries. in addition, Huawei accounts for two or 1/4 of the bearer networks of the three major carriers in China, excluding political factors. junipor is doing well in China Mobile and China Telecom. In terms of transmission, Ericsson and Huawei and Alcatel account for many of them. Cisco does not, In terms of ATM, Cisco and
