6-3-36. CBI_M2_RETRIEVE_BSNT The L3 sends this message to L2 to request that it process all data messages
received so far, and then send a CBI_M2_BSNT signal back to the L3 to
inform it of the sequence number of the last received message.
In the case where the sequence number cannot be obtained, the L2 sends
back a CBI_M2_BSNT_NOT_RETRIEVABL message.
