摘　　要：随着当代通信和网络的进一步发展，话音、数据和图像等多媒体通信成为当前研究的热点，数据传输量以指数形式增加，这对通信传输系统的处理能力和吞吐能力提出了更高的要求，使同步数字体系（SDH）网络趋于复杂，容量也越来越大。SDH是一种将复接、线路传输及交换功能融为一体，可实现网络保护管理、实时业务监控等多项功能，能大大提高网络资源利用率、实现灵活可靠和高效的网络运行与维护，成为当今世界信息领域在传输技术方面的发展和应用的热点。SDH数字交叉连接设备（DXC）作为SDH传输系统的重要组成部分，是一种兼有复用、配线、保护／恢复、监控和网管的多功能传输设备，对整个光纤系统的传输能力有着直接的影响，已经成为评价SDH系统传输能力的一个重要指标。These years, with the further development of communication and network technologies, multimedia communication, such as the transmission ofvioce, data and pictures, has becomes a research hot spot. The through put of data transmission service increases exponentially, so it requires the communication transmission systems providing much enhanced data progressing ability and capacity. At the same time,SDH network has to accommodate its complexity and performance to data transmission service. As one of the most key parts of SDH transmission system, SDH digital cross connect equipment have multiple functions, such as multiplexing connection layout, protection,recovery,real-time check and control and network management. The performance of SDH system DXC has great effect on the whole optic communication, and is considered as an important performance guidline of SDH transmission equipment capabilities.
