High-speed Internet access and for telecom network applications， greatly promoted the development of Access is an important part of telecommunication From the perspective of the theory of copper and fibre， summarizes the characteristics of wireless access technology and Also according to the cities， based on the status of the access of hierarchical planning model， optical access to access the main city fiber distribution layer， such planning and design are Also introduced from actual Angle access layer， convergence layer core， as required from six aspects: xDSL access system design should pay attention to the direction and And to the school， family， hotel and examples， the most mature technique most widely used ADSL
High-speed Internet access and telecommunications network applications， which greatly promoted the development of access Telecom Access Network is an important component of the This paper provides an overview of the theoretical perspective of copper， fiber， wireless and other access network technologies and their At the same time， urban access network in accordance with the status quo， combined with fiber-optic access network hierarchical planning model for urban trunk optical fiber access network layer， distribution layer， such as planning and design are Also presented from a practical point of access layer， convergence layer， the core layer， such as xDSL access network systems should be designed six of the direction and focus of And to schools， hotels， family and other common examples of the current technology the most mature， most widely used of the ADSL
