基于C51的SOHO PBX设计

The Design of SOHO PBX Based on C51

多用户、多业务的 IP网络系统是统一通信网络的重要形式之一。通过分析 IP电话的通信原理和发展现状 ,提出了一个基于 Vo IP技术的多用户、多业务 SOHO PBX系统 ,介绍采用单片机高级语言C5 1编写 SOHO PBX应用软件的方法及其工作原理 。

IP access network is a technique that enables the traditional communication services to be carried out on Internet.Based on our understanding of IP telephone communication principium and its development status quo,we propose a multi function system the SOHO PBX which can provide multiple communication services including voice,fax,data in the Internet by one set of equipment.In this paper we first introduce a method for the design of SOHO PBX based on VoIP and then describe the approach for realizing the software by using C51.We finally give a report on the results of a test conducted for the proposed SOHO PBX.
