摘　　要：研究由不同网管管理的、两个速率不同的传输系统的"逻辑叠加"组网,即利用高速率传输系统提供透明通道以搭载低速率传输系统;以调整传输设备逻辑叠加组网时出现的低速率传输系统上报"DCC连接失败"为例,研究SDH帧结构及开销字节的运用规则,调整数据设置方式,并通过实验进行功能验证,解决SDH传输系统逻辑叠加组网时的数据设置问题,从而释放光缆资源,提高传输资源利用率。This paper mainly discusses the "logical overlay" network of two transmission systems with different rates under the government of different network management, that is, using the transparent channel provided by the high-rate transmission system to carry the low-rate transmission system. In the case of the low-rate transmission system reporting "DCC connection failure", the application rules of SDH frame structure and overhead bytes are studied and the data setting mode is adjusted and verified by test in order to solve the data setting problem in SDH transmission system logical superposition networking, thus releasing fiber optic cable resources and improving the utilization rate of transmission resources.
