Looks like you have a potential synchonisation issue. You will need to look at your “jitter” and “wander” settings. Check that you inital
synchonisation source is stable and is cascaded from the ingress point right down to the Radio Network. If the Network is not synchronised
soon (after a period of several hours) your nodes will become despotic.
The Synchronisation source helps to “pull” or “reign in” nodes that are becoming
despotic. Compare this with a phase “locked-loop” approach. For Data Traffic slips
will cause impairment and this leads to information loss.
