Short Description SI-FECForward Error Correction, also known as FECForward Error Correction-S, FECForward Error Correction 1000 Simplex, and FECForward Error Correction-1000S, was the FECForward Error Correction variant of SI-ARQAutomatic Repeat reQuestAutomatic Repeat Query, and was only used under extremely poor propagation conditions. SI-FECForward Error Correction was developed by Siemens and was used by Austrian and Indonesian diplomatic services.

SI-FECForward Error Correction, also known as FECForward Error Correction-S, FECForward Error Correction 1000 Simplex, and FECForward Error Correction-1000S, was the FECForward Error Correction variant of SI-ARQ, and was only used under extremely poor propagation conditions. SI-FECForward Error Correction was developed by Siemens and was used by Austrian and Indonesian diplomatic services. No longer used today.

SI-FECForward Error Correction typically uses baudrates of 96, 192 or 200 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. using the ITA-3 alphabet. During idle mode this system is the same as CCIR 242 (ARQ-M2).
