SECBR (Severely Errored Cell Block Ratio)

In asynchronous transfer mode (ATM), a dependabil-

ity parameter expressed as the number of severely errored cell blocks (some number of cells transferred in a sequence) compared with the total number of cell blocks sent over a period of time. A severely errored cell block outcome is realized when more than some number of cells in a block is errored, lost, or misinserted. See also ATM, block, and cell.
