尽管SDH的网管会因厂家设备的不同而在处理的操作上存在差异,但网管的机理是符合ITU-T标准的,因而要做好SDH网管的关键是要对SDH信号的复用流程和用于管理的开销字节进行分析。主要通过对SDH网管中标记字节(C2/V5)和通道踪迹字节(J1/J2)的分析,并结合SDH网管的维护经验,对传输网资源的维护和管理提供了新的方法。
Although the network management of SDH is different in operation due to different manufacturers’ equipment, the mechanism of network management is in line with ITU-T standards. Therefore, the key to SDH network management is to reuse the SDH signal and use Analyze overhead bytes for management. Mainly through the analysis of tag byte (C2 / V5) and channel trace byte (J1 / J2) in SDH network management, combined with the maintenance experience of SDH network management, it provides a new method for the maintenance and management of transmission network resources.
