PURPOSE: A data resending system for an exchange system is disclosed to increase reliability and provide an effective management by resending data when an error occurs. CONSTITUTION: A data resending system for an exchange system includes an address decoder(13-1), a frame signal generator(13-2), a data latching part(13-3), a data converter(13-4), a transmission latch clock generator(13-5), an address converter(13-6), and a relay part(13-7). A data resending controller(13-8) is further provided to latch data and address inputted from the data latching part(13-3) and the address converter(13-6), and to detect a sending error which occurs when data is sent using a parity check function, and to resend the data latched when the data sending error occurs.
