摘要
设计了一个用于SDH网络分析的E1、T1信号解映射和帧处理电路。该电路能从符合ITU-TG.707标准的SDH虚容器VC-X中解映射出符合ITU-TG.704标准中所规定的E1、T1帧结构的PDH数据,对解映射出来的信号依据各种帧结构进行解帧和解复帧处理,并进行各种告警检测和性能分析,同时输出处理好的PDH净负荷。该电路也可以对PDH电信号中的E1、T1信号进行帧处理。
This paper designs E1/T1 demapping and frame processing circuit for SDH network analyzing. In the circuit, E1/T1 signals in PDH data under ITU-T G.704 standard are demapped from SDH virtual containers under ITU-T G.707 standard, and undergoes frame and complex frame decoding based on suitable frame structures. Warning detection and performance analysis are also done while the final PDH payload is output. In addition, the circuit can also process E1/T1 directly form PDH electronic signal.
