Hi,
I do not know SDH, thus seek help here. I am working on a project
which needs the accurate frequency information. We plan to get that
from E1/T1 dropped from SDH. As far as I know, SDH has pointer
adjustment to accommodate different signal sources or other
imperfections. I want to know the maximum SDH pointer adjustment
period for a stationary resource (which has a fixed, small frequency
offset). With that SDH time adjustment period, I can design an average
fuction to get the accurate frequency.


Thanks a lot.
