The user must copy the link entries of DXB Linktable or DXB
Subscribertable, without Dest_Slot_Number and Offset_Data_Area, in the
DXB_Link_Buf and set R_Len_DXB_Link_Buf. Also the user must enter the
default status message in DXB_Status_Buf with the received links and
write the appropriate values to R_Len_DXB_Status_Buf. After that, the
parameterization interrupt can be acknowledged.
