Abstract
In an SDH telecommunications system, a buffer overfill/underfill problem, which is consequent upon either a synchronization failure or an excessive amount of wander, is overcome by detecting such failure or wander and temporarily changing the mode of operation of a de-synchronizer at a terminating end of the SDH path. A Synchronization Status Messaging Byte (SSMB) is used as an indicator of the quality of the incoming bearer timing.
