Hello Richard,
You wonder:
Hello hubb,
(my name is Huub)
What is synchronisation meaning?
It is the "S" in SDH. This networking technology is based on the
fact that all elements are synchronised to the same network clock
What is the need SDH network elements are to be synchronised?
Because SDH means "Synchronous" Digital Hierarchy.
without synchronisation the SDH network does not work faultlessly.
Can you explain me with some practical scenario?
Like what will happen if it's not synchronised?
I cannot explain that in a few words, search the internet for a
good SDH tutorial.
And how SDH elements maintaining a same clock throughout the network
They use the recovered clock received from other elements.
And use that reference based on the timing hierarchy provisioned
in the network.
How the value of SSB byte and synchronisation is related
The SSM contains the quality of the clock in the same signal,
this quality is used to select the reference clock.
Regards, Huub.
