| ADSL has a very rapid development in China because of the advantages of the cost, price and safety. With the extending of ADSL access net, there are some important problems that every telecom company is exploring, such as how to build reasonably, maintain and manage developing ADSL network, how to optimize the existing ADSL network to reduce the operating cost and satisfy the market needs farthest.In this article, some conception such as access network and technology are introduced. According to the international G.992.1~G.992.5 standard, compared with ADSL, VDSL and ADSL2+ technical characters, xDSL access technology is studied in detail. Being considered ADSL network is a part of broadband access network, which is built on existing IP broadband local area network, the operating and supplied business status of Hefei telecom IP broadband local area network is studied particularly. This is also the theory evidence for this work in the article.Based on study and analysis of Hefei telecom ADSL access network status, some familiar methods about building ADSL access network are illustrated. Based on analyzing the present needs of Hefei broadband market development, the emphasis is given that optimizing IP local area network and the structure of ADSL access network, rebuilding transmitting cable, choosing the type of business, optimizing network flux, strengthening the user proof and management, and so on. Further the structure design method of ADSL access network in some area is given. Meanwhile, combined with the experience of maintaining the telecom ADSL access network, many ways to solve many frequently asked questions about communication are given. It is meaning for application and satisfied the needs of the telecom engineering maintenance.In the conclusion, according to the author's operating and managing experiences, some suggestions aiming at the development of broadband net are given. All of these can supply references to the decision-makers of China telecom operation. |
