G3 ECM (G3 Error Correction Mode) • G3 ECM is the error correction system newly recommended by Consultative Committee of International Telephone & Telegraph of 1988. • By G3 ECM, documents are divided into blocks (called partial page) for transmission. If any error takes place in any frame (one partial page consists of 256 frames) on a partial page, the receiving party generates the retransmit request with erroneous frame num- bers.
