Dear, CM!
If you are still interested this question.. There is no strictly defined restrictions on TBF lenghth. BSN parameter is used for Backward error correction and sequence control, also for correct re-assembly LLC PDU on receiver side. There is no such rule about two blocks with the same BSN, but there is one that each subsequent received block has to have BSN = [BSNprevious block +1] mod128.
