3.7 Configuration Check Number (CCN) and the Office CCN (OCCN)
The software used in the GCP5000 generates a 32-bit Cyclical Redundancy Check (CRC)
number to determine that the software data has not been corrupted. Corrupted data would
display a different CRC value. The GCP5000 takes the CRC of all configuration data and
derives a Configuration Check Number (CCN) from that. Since there are values that are set in
the field, the software derives an Office Configuration Check Number (OCCN), which is the 32-
bit CRC of the configuration data, excluding items that are protected by the Field Password.
