Definitions for "Longitudinal Redundancy Check"
Keywords:  lrc, bcc, error, parity, previous
A data communications error trapping technique in which a character is accumulated at both the sending and receiving stations during the transmission and is compared for an equal condition, which indicates a good transmission of the previous block.
A method to make sure data is received correctly. Consists of performing parity checks across the data message.
An error checking technique based on an accumulated exclusive-OR of transmitted characters. An LRC character is accumulated at both the sending and receiving stations during the transmission of a block. This accumulation is called Block Character Check (BCC), and is transmitted as the last character in the block. The transmitted BCC is compared with the accumulated BCC character at the receiving station for an equal condition. An equal comparison indicates a good transmission of the previous block. Compare with: block character check, cyclic redundancy check, and vertical redundancy check.
