DUP-FECForward Error Correction-2 is a further development of the DUP-ARQ system and the system characteristics are very similar. Uses FECForward Error Correction instead of ARQAutomatic Repeat reQuestAutomatic Repeat Query and runs at either 125 bdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. or 250 bdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second.. Like DUP-ARQ-2, DUP-FECForward Error Correction-2 allows transmission of ITA-2 (Baudot) or ITA-5 (ASCII) characters.
