Does your Network have a Synchronisation master plan?
From experience two paths (for redundancy and resilience) is used to ensure that a stable “clock” signal can be propagated to each element in the Network. One source will be from an atomic “clock”.
To reign in a fast node a PLL approach is used.
For BTS it will get a “clock” signal from a higher order element (BSC/MSC). If the “clock” signal is lost the element will become despotic, i.e. it will be at odds with the rest of the Network.
