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.
