基于PowerPC MPC8260软交换信令资源板的研究

Design of softswitch signalling resource board based on MPC 8260

将传统电信网络中业务、控制与传输分离开的软交换技术,实现了IP网络和传统公用交换电话网(PSTN)的融合互通。在众多信令网关设备中,信令资源板为其最重要的组成部分。介绍了以MPC8260通信处理器为核心的软交换信令资源板的设计方案,详细说明了以MPC8260处理器最小系统设计的通用处理平台及100Mbit/s以太网通信接口LXT972。

Softswiteh separates operation,control and transmission in traditional telecommunication network and amalgamates IP network with PSTN（Public Switch Telephone Network）. The signalling resource board is the most important component of signalling gateways. A design scheme of signalling resource board on MPC 8260 processor is introduced. The general processing platform of the least MPC 8260 system and 100 Mbit/s Ethernet communication interface of LXT 972 are expounded.
