摘要
文章在分析2 M信号复用和映射到SDH设备的基础上,对通道时隙编号和线路时隙编号的对应关系进行了论述,提出了根据对接中相应告警信号对高阶通道开销进行处理的方法,介绍了SDH设备与数据设备等非SDH设备的互联互通方法。通过这些方法,可有效解决SDH接口对接中出现的问题,整合不同厂家的SDH设备资源,优化传输网络结构,方便运行维护,提高SDH设备的利用率和传输通道的可靠性。
This paper discusses the relationship between numbering of channel time slot and line time slot by analyzing multiplexing and reflecting of 2 M signal to SDH equipment. It introduces a method of processing high-order overhead by relevant warning signal, describes the interconnection method between SDH and data equipments. By these ways, some problems occurring in SDH interface connection can be solved. This method will optimize network structure, improve the reliability of transmission channels and utilization ratio of SDH equipments.
