Construction of new broadband access network

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 network of the whole solution. ——— Editor

Xpresslink according to the different needs of customers to provide a variety of Client interface: for residential users to provide full speed ADSL and ISDN users with ADSL, etc., for business users to provide up and down Shuchong rate of 2. 3Mbps SHDSL, which will provide a VDSL solution for higher-requirements users. Xpresslink is connected to the core network through a standard interface.

At present, the telecom operators in the procurement of DSL equipment often used DSLAM and CPE unified tendering method for procurement. This method can be used to solve the interoperability problem of DSLAM and CPE for operators. And in this will Dslam and CPE to bundle the procurement for operators to bring convenience at the same time, but also brought new problems for operators: With the increasing number of users, terminal equipment is also increasing the absolute quantity, in the face of more and more terminal equipment, operators how to maintain?

According to Dataquest forecast, by 2002, more than 15 million CPE will be put into use in the world. Early in the telephone promotion of the earliest, the telephone is usually provided or designated by the operator. With the standardization of the market, today's users are free to buy the necessary equipment in the market. Dslmodem is similar to the telephone, with the fierce market competition, DSL mainstream chips highlighted, TI and Alcatel become the current ADSL market share of the most chip manufacturers. This is the prerequisite for CPE Marketization: Dslam and CPE must follow the relevant international norms to ensure good interoperability.

In the current case where the operator provides CPE to the end-user, CPE is vested in the operator and the obligation to maintain CPE belongs to the operator. This kind of maintenance will greatly improve the operation cost of operators, how to reduce expenditure, and improve the operators ' income has become a new problem faced by operators.

Siemens has specially developed a powerful network management system after fully considering the convenience of operator operation and reducing the requirement of operation and maintenance cost. In addition to the functions of business management, performance management, configuration management and fault management, there are two most distinctive functions in this set of NMS, namely Diagnostictools and Lineconfigurationtools. Diagnostictools is the diagnostic tool, which can help operators to find the fault point accurately after receiving the user's declaration, analyze the cause of the failure, even detect whether the CPE is normal, and can find the user name and password entered every time when the user is on the internet, and compares the username and password in the original record of the previous normal access to confirm that the user is doing the right thing. This diagnostic tool avoids unnecessary work in the operations department due to improper operation of CPE equipment or users. Lineconfigurationtools, the Line Configuration tool, on the other hand, simplifies the miscellaneous work of the operation and maintenance department.
