Template:Refimprove In telecommunications, a block check character (BCC) is a character added to a transmission block to facilitate error detection.
In longitudinal redundancy checking and cyclic redundancy checking, block check characters are computed for, and added to, each message block transmitted.[1] This block check character is compared with a second block check character computed by the receiver to determine whether the transmission is error free.
