Hi everyone. One question : are there any layer 3 messages that would span across multiple LAPDm frames? Or are they chosen such that this never happens? Thanks, Mihai.

'normally' it does not happen, i.e. for regular voice / sms operation. But there is no guarantee for that.
However, I believe in the context of RRLP or other LCS related procedures, they may very well happen.
It is our experience that not even all BTSs on the network side support LAPDm fragmentation/reassembly - so it may be safe to assume that it is not any different for phones.
