resources are limited, the original uplink mode can be retained; if the number of users exceeds 200, you can merge multiple DSLAM users into one DSLAM device based on the actual situation, and use GE uplink. 3) the original use of STM-1, E1 and FE cascade DSLAM, can be removed according to the specific circumstances, and according to the above principles using d

SoftX3000 through TMG8010, the Softswitch is used to process V5 signaling and complete V5 user access. TMG8010 supports downstream V5 access. After TMG8010 ends V5 signaling, it is converted to H.248 and reported to the softswitch for processing, access V5 users. For the voice access of traditional xDSL users, the DSLAM device enables comprehensive access to user-side voice and data, implements voice and data separation on the

They have different transmission features, market positioning, physical location, and problems to be solved, in the future, many technologies may coexist in actual access networks. This article will introduce some major Wired Broadband Access Technologies. At present, the main wired broadband access technologies include: ordinary Modem, N-ISDN narrowband integrated business Digital Network), Cable Modem and hfc-fiber coaxial Cable), HDSL high-speed digital user loop) sym

ADSL System structureThe ADSL system consists of an office-side device Dslam (digital subscriber line access multiplexer, a user-user-cable multiplexer) and a customer-side device

Siemens, Germany, has launched a full range of DSL solutions to support the rapid development of the communications industry in response to the broadband and data features of communications networks. Siemens, the largest overseas joint venture Beijing International Exchange System Limited (BISC), has introduced the product ——— Xpresslink to China. Xpresslink with Siemens other data products to provide users with powerful, operator-oriented broadband n

, we can see that the application of the PON system and VDSL2 can complement each other to extend the coverage of optical fiber cables, at the same time, flexible and economical use of optical fiber and port resources based on business needs can protect Telecom's existing advantages in copper cable resources, shorten engineering construction periods and reduce costs, and quickly meet business needs. From the perspective of application scenarios, the copper cable is gradually shortened as the fix

VoIP), high-speed Internet access 5 Mb/s ). ◆ FTTN: for the broadcast and television business, ADSL2 is used for access from the transfer box, 15 Mb/s, 1 high-definition channel or 3 standard channels plus IP voice service VoIP) and 1.2 Mb/s for high-speed Internet access ). The user's requirements for a variety of businesses promote operators to adopt the solutions most suitable for future development, which can meet both needs and make profits.Cost of various solutions Table 1 calculates the

From DSL to optical fiber entry, the speed ranges from dozens of K to dozens of M or even hundreds of M, and the broadband access technology has undergone dramatic changes over the past decade. EPON has been used in Japan and South Korea for many years. GPON is always around the world, and 10 Gbit/s PON and other access technologies that can bring higher bandwidth are ready for use. As the broadband network is booming, the competition for technology s

terminal, a single optical fiber (4 km) to the center data center of the residential area, and a Optical Splitter (0.8 km) to the building in the center data center of the residential area, each corridor uses a Optical Splitter (0.2 km) to access each floor, and then uses five types of lines to access the user end. Each ONU has a layer-2 switching function. Considering that ONU has 16 FE ports, that is, each ONU can access 16 users, which are calculated based on a model of 500 users. FTTC + EPO

Each ADSL user has a separate telephone line connected to the ADSL terminal, the structure of which can be seen as a star structure, its data transmission bandwidth can be guaranteed and by each user exclusive. In addition, because of the use of ATM transmission technology, its data transmission has a certain degree of security and confidentiality.In 2001, ADSL as a broadband access technology has been widely used in the country, of which, Beijing Telecom has investe

1. dslam (DSL access Multiplexer): digital user line access multiplexing, that is, a modem combination connected to a multi-channel compound system center. It collects signals from multiple DSL connections and converts them to a high-speed line, it is used to support video, broadcast and television, fast Internet access, and other high-value applications.

In the process of construction of metropolitan Area Network, the construction of broadband access network, namely user Resident network, is a hotspot. As a form of broadband access, information community access is being widely concerned by operators. In practice, the current popular broadband access technologies are: ADSL, Ethernet, home PNA, APON, LMDS, HFC and so on, and more mature and reliable, universal implementation of access to two types: ADSL broadband access Mode (mixed-type

Http://bbs.dev.ccidnet.com/read.php? Tid = 586331 Introduction A domain-specific language (DSL) is usually defined as a computer language that specifically targets certain special problems. It is not intended to solve non-domain problems. The formal research on DSL has been going on for many years until recently, when programmers try to solve their problems in the most readable and concise way, internal

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

, 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

DSL technology and services are one of the fastest growing areas of broadband networks. The development of new-generation ADSL chips has been ongoing in the process of standard formation. Different chip manufacturers adopt different strategies. At present, the ADSL2 chip has preliminary products, and more products will be launched this year. The development of new-generation ADSL: On the one hand, because the new generation of ADSL does not change m

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,
