摘　　要：分析了开滦集团融合通信系统、宏丰公司通信系统现状,规划了宏丰有线通信系统与开滦集团机关融合通信系统互联架构,编写了内部中继注册网关等设备SIP协议底层脚本,实现了从传统、封闭、窄带语音通信模式到语音、文本、视频等多媒体通信的跨越,研究了MSTP+VPN多源链路传输模式,设计了MSTP+VPN链路切换模式,编写了核心交换机、防火墙等设备底层脚本,提高了传输链路的安全性、可靠性、可用性。This paper analyzes the present situation of Kailuans converged communication system and Hongfeng Company's communication system is analyzed.The interconnection architecture between Hongfeng wired communication system and Kailuan group's converged communication system is planned.The underlying script of SIP protocol for internal relay registration gateway and other devices is written,which realizes the leap from traditional,closed and narrowband voice communication mode to voice,text,video and other multimedia communication.The MSTP+VPN multi-source link transmission mode is studied.The MSTP+VPN link switching mode is designed.The underlying scripts of core switches,firewalls and other devices are written,which improves the security,reliability and availability of the transmission link.
