My question of FCS-Frequency Check Sum is related to the LAPDm part of GSM. The Abis interface to be more exact, and the string of ones is used for synchronization on layer 2(which you have correctly pointed out).
The SCH is on the Um interface between the BTS and MS, as I understand. And not related to my question specifically.Thanks for your input so far.
