The Research And Design Of Embedded Access Network Interace Protocol

Along with the coming of computer age, digitizing, broad banding and intelligentization became the trends of future communication progress. Users put more expectations to communication service. Access network connecting local exchange with user is an important part of telecom network. It also is the case of telecom network's digitalization, broad banding and service integrating. Many countries attach more importance to construct access network.Embedded system is a special computer system, which is based on hardware design and software development and oriented to application. Embedded system is widely used in industry production, procedure control, telecommunication, vehicles, aviation and electronic consumable goods. Integrated with telecommunication system, embedded system can exhibits its strong power.Embedded access network interface protocol development based on Real Time Operation System is a promising area and has far-reaching theory research and practical application value. This paper is written at this background. Its research is mainly concentrated on the following aspects: embedded system architecture and Real time operation system are researched; access network communication interface protocol is deeply investigate; embedded implement AN V5 interface is intensively studied; general protocol software implement method summarized; broad-band V5 interface is researched and designed.This article firstly analyzes V5 interface protocol and deeply research protocol's architecture. Secondly, we study the structure of Embedded system, the general design method of embedded system and the system component.Thirdly, we research the scheme of implement V5 interface based on RTOS.At last, this article analyzes the design of broadband V5 interface protocol.
