摘要
基于VoIP并采用PON接入方式的语音专线已成为集团客户市场的主流解决方案。传统的TDM语音专线依托SDH接入方式仍然保有可靠性优势,因此提出了一种不依赖SDH和传输保护技术的VoIP专线可靠性优化新方案,论证了该方案具有低成本高效益的特点,详细分析了该方案通过多网协同达成组网目标的具体方法,最后通过实验室测试和现网试用,导入真实业务,从而验证了方案的合理性、可行性以及稳定性。
The voice line based on VoIP and adopting PON access has become the mainstream solution for the enterprise private voice line service market. The traditional TDM voice line still retained the reliability advantage based on the SDH access. Therefore, a new VoIP line reliability optimization solution that didn’t rely on SDH and transmission protection technology was proposed. The lower cost and high efficiency of the solution was demonstrated and the specific method of the scheme was analyzed to achieve the networking goal through multi-network collaboration. Through both laboratory test and present network trial, the rationality, feasibility and stability of the solution was verified.
