Hi,
How does the BTS judge if the clock satisfies its
needs? Less sophisticated
systems don't care and simply are unstable / off the frequency when the
master clock is unstable / off-freq. The question is just because I am
technically interested in the topic. Everyday there pops up some exciting
stuff to learn out there :)
I can't be 100% sure, but my understanding is it just compares to its
internal OCXO.
It know the margin of error of its OCXO, so if the incoming freq is
more different than what it expects,
Either the OCXO went bad or the incoming clock is bad. In either case,
it's a fault.
Cheers,
Sylvain
