METHOD FOR CHECKING ERRORS IN BLOCK OF DATA TRANSMISSION SYSTEM

摘要

PURPOSE: A method for checking errors in a block of a data transmission system is provided to check the generation of errors in a signal transmission block at an on-line state and in parallel transmission. CONSTITUTION: A data processor(2) of a transmission party processes inputted parallel data, to transmit the data to a data processor(8) of a Unit-2 in a receiving party in parallel. A parity check circuit(12) transmits a result of a parity check by the unit of bit for transmission data in a parity bit through a line(L1). The receiving party receiving the parallel data and parity bit checks a parity in a same manner with the transmission party in received data, and compares a checked result with the parity bit, to confirm the generation of errors.
