摘　　要：时钟同步是数字设备协调无误运行的前提条件。文章针对目前广泛应用的SDH自愈环系统的同步问题进行了较细致的探讨，并提出了在复用段倒换环中将APS协议与同步状态信息的实现相结合的新观卢、，拓开了同步问题的解决空间。Clock synchronization is the precondition for digital equipment to work in harmoniously. To aim at synchronization problems of the widely used SDH self-healing rings, the paper gives a discussion, and puts forward a viewpoint. In the MS shared protection rings, if combining the message of APS to realize the functions of synchronization state byte S1, we should have a larger space to solve the synchronization problems.
