PCU sends invalid block number to L1

Hi All, We have noticed that the PCU sends invalid block number to L1 in DSP leading to unexpected message warning in DSP "GsmL1_PhDataReq(1) : Unexpected burst (Invalid blockNumber) [2!=1, SAPI 21-21]]". After an investigation, we observe that the 'pcu_rx_rts_req' function in pcu_l1_if.cpp receives invalid block number from BTS. Looking at the BTS side, the calculation of L1SAP_FN2PTCCHBLOCK defined as '#define L1SAP_FN2PTCCHBLOCK(fn) ((fn / 52) & 7)' does not seem to be valid for expected PTCCH block numbers B0, B1,B2,B3 defined in Table 6 in TS 05.02 version 8.11.0. What do you think about re-define the calculation of the L1SAP_FN2PTCCHBLOCK?
