Abstract:
1. A regenerative relay apparatus comprising: a decoding part configured to make an error correction of data by using an error correction code; an encoding part configured to generate another error correction code from data after the error is corrected; an error count part configured to count an error rate before the error is corrected; a transfer part configured to transfer the error rate before the error is corrected from a latter apparatus; an adding part configured to add the error rate in the regenerative relay apparatus and an error rate reported from the latter apparatus by a notifying part; and a selection part configured to select the error correction code and data before the error is corrected in the regenerative relay apparatus so as to be supplied to the latter apparatus if the added error rates are lower than a designated error correction threshold, and configured to select data after the error is corrected in the regenerative relay apparatus and the other error correction code generated from the data so as to be supplied to the latter apparatus if the added error rates are higher than the designated error correction threshold.
