摘要
SDH环网中,在向多个网元提供多个外时钟源时,若根据ITU-T标准算法配置时钟源可能会导致时钟成环,现将分析几种SDH组网类型的时钟配置可能出现的时钟成环情况和导致时钟成环的原因,得出了几种避免时钟成环的结论。
It is possible for the SDH Ring Net to make the timepiece loop at many timepiece working by ITU - T Standard. The paper analyzes some typies of timepieces in SDH Net, describes the cause to result in looping of ring - forming SDH system, puts forward the messages to avoid this accident.
