摘要

现实社区与数字化技术所营造的虚拟社区的有机组合可形成数字化社区，数字化社区的核心部分是通信网络建设：传输速率有所不同，可以通过各种通信信息和数据的属性不一样，可以用宽带网络传输，用户需要用其他网络传输线路来传输到用户室内，则需要建立用户终端设备和各种业务网的业务节点之间各种关联网络，即数字接入网；它是一种传输网络的业务网，其功能是能够建立各种业务网与用户终端设备信息传输的要求，可以综合业务的接入，尤其是Media业务和IP业务的综合接入。

本论对接入网络的物理型态、业务功能及数字交换、复用等进行了深入探讨与研究,对数字社区中的通信体系进行了方案设计,比方说光纤网接入、铜缆网接入、HCF网接入等设计、在以太网接入过程中可以完善相关的方案及无线网接入;最终坚持利用这些数字性的社区系统实现工程化,同时在有线及无线接入中进行工程设计,并对这些方案的设计要素进行分析,进而实现了相应的性能。

FTTX+ADSL+HFC/LAN将接入网的设计方案通过光纤形式接入并实现了综合宽带的接入,很容易实现社区不同信息的满足。数字性的社区通信体系在接入过程中，可以实现的解决方案主要是FTTH,并将所有业务接入。

Abstract

Digital community organic composition real communities by the digital technology to create a virtual community, the communication network construction is the core of digital community: The properties of the various communication information and data of different transmission rates vary, through the broadband network transmission, the user do not want a variety of business network transmission line respectively to customer premises, the objective needs to establish a connection between the user terminal equipment and a variety of business network service nodes integrated transport network that modern access network; it has nothing to do with the business transfer network, to meet a variety of business information between transmission networks and user terminal equipment requirements to achieve access to the integrated services, especially integrated access services and IP multimedia services.

The theory explores the physical access network showing the reference type, involved in theoretical research and business functions characteristic of digital switching, digital multiplexing technology, pointed out the figure of community-based programs designed to access the communication system such as fiber access network, the copper access network, access network design HCF programs to achieve access to the appropriate program design and design of wireless networks via Ethernet access; eventually insist these figures of the community system implementation engineering, simultaneous engineering in wired and wireless access, and the design elements of these programs are analyzed, so as to realize the corresponding performance.

FTTX + ADSL + HFC / LAN to the access network through the fiber in the form of access to the design and implementation of integrated broadband access, it is easy to meet different information communities. Community of digital communication systems in the access process, the solution can be achieved mainly FTTH, and all service access.
