Figure 3-5 The FBR receives the information
At the encryptor, the FBR code containing the BRC performance message is
decrypted. The FBR does know what FBR code it was expecting from the other end
and can compare the received code with the expected code.
Figure 3-6 The FBR decodes information and rebuilds registers
Using an algorithm, the FBR extracts the BRC performance message from the
received code. It then uses these extracted BRC performance messages to
reconstruct the Black Zone performance registers.
