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.
