When you suddenly not on the net, what will you do, you may check whether the router is normal, enter the router access address such as 192.168.1.1, you can log on to the success of the router can confirm that there is no problem. And when you find that the icon in the lower right corner of the desktop turns gray, the X-state, you need to check the interface is good. When checking the cat interface, you need to pay attention to a place that is the cat's indicator light! You may find that the ori

Veteran operators want to make full use of XDSL technology to transfer large bandwidth business, it is necessary to shorten the length of the user's copper cable, so the "light into copper back" work will be long-term, cloth put more fiber, the optical node to the user side, Dslam, such as

the channel utilization and data exchange more effective due to the superiority of ATM itself.* Dslamdsl atm multiplexing): This is a local device that provides the ADSL service. It is similar to a local program-controlled switch.* Service-provided telephone lines: currently, the ADSL service uses a common analog telephone line to provide services that support both voice and data. Some customers once asked if the ISDN line can be converted into an ADSL line. In fact, ISDN provides digital trans

devices for voice and ADSL Network signals in the telephone line, and sends the signals to different telephone devices (telephones, fax machines, etc.) and ADSL MODEMsynchronization for synchronization respectively. The ADSL Network signal connection process between the ADSL client and the local end. After the two sides establish a connection (synchronous), The ADSL can be used.

VPIVirtual Path Identifier) is the virtual Path Identifier, VCIVirtual Channel Identifier) is the virtual Channel Identifier, VCI/VPI is the sign or secret number of DSLAM to identify ADSL lines of various ATM terminals. Different service providers in different regions have different parameters.

broadband access network) two Application Methods. BeforeUsers can reduce the cost of the ATM switch, simplify the network structure and increase security. The latter can increase network flexibility, reduce network costs, and provide network service scalability.4 network implementationIn the actual network planning, the STN can be used as the transmission in the network to connect to the Taiping station. There are three application Hotspots: 1) replacing the ATM edge switch to reduce network c

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

network unit, such as DSLAM, can often be connected to hundreds of users. For such a network distribution and so many single-point connected users, it is also an ideal choice to switch the Broadband Access Server from centralized access to decentralized access. It can even be directly integrated with edge access devices on the Access side to integrate IP addresses directly connected to the network. This networking scheme is not only conducive to simp

LED indication on iODN equipment can realize automatic optical fiber searching and precise operations, greatly improve the O M efficiency, and achieve efficient operation and maintenance of the ODN network. In addition, based on the iODN architecture, a variety of value-added applications can be developed based on the existing system to automate the entire process of construction and O M. Introduce MPLS to the access layer With the advancement of FTTx, on the one hand, the traditional leased

(which might help improve the DSL terminal signal to suppress the echo signal). This ensures that DSL modems and telephones only accept the signals they are designed to use. If the "wires-only" service is used, the user can insert the filter into an existing telephone slot, or the DSL operator may install it.Using the Digital subscriber line access Multiplexer (DSLAM) at the switching station, the data on the DSL circuit is aggregated and forwarded t

Ethernet interface, can be used for streaming media applications on the LAN, but mainly used for communication with the control system, such video server can only be used for local applications, And can only be used for streaming media applications based on IP mode. At present, due to the progress of Ethernet technology, IP over SDH and IP over DWDM technologies such as the mature, LAN and man, the difference between the gradual disappearance of IP streaming media can easily be a large applicat

broadband access network technology, so far, there is still no perfect solution, Each program has its own 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 networ

(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

information, the header stack is also supported to improve scalability. Similar to ATM and MPLS networks, tokens sent by users are tagged. Once a tag is inserted, network devices can process data tokens 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 i

networks, and BRAS/SR. Because the internal network of the broadband access network is complex and involves multiple technologies, it is a good solution to achieve QoS by adopting the DiffServ idea at this layer, that is, the policies adopt business differentiation and marking, business ing and classification bearer, and Layer 2 802.1D priority processing. The DiffServ framework is suitable for all networks using the ADSL access mode. There is no essential difference between the ADSL service di
