摘要
近年来,Internet得到了飞速发展和普及应用,而作为其核心技术的IP协议体系在数据网络架构中的统治地位已得到了广泛认同。同时,随着基于IP技术上各种应用技术尤其是VoIP技术的提出,数据网络通信逐渐融入了传统的话音业务领域。详细论述了在硬件上如何设计和实现VoIP语音网关。首先对VoIP技术进行了介绍,进而详细论述了基于ARM网络处理器S3C4510B的具体实现方法,最后对VoIP网关进行了系统测试和结果分析。
Internet has been unprecedented progress and widely applied in recent years. But the status of IP protocol system as a core technology has got the extensive approbation in the data network. At the same time, along with every technology being put forward, particularly VoIP, it makes data network correspondence melt into the traditional voice business gradually.The hardware design and implementation of the VoIP gateway are discussed. Firstly, the technology of VoIP is summed up. Secondly,the hardware circuit design based on S3C4510B is decribed in detail. At last, system test and result are given.
