Abstract
Within a fixed infrastructure of a communication system, message portions of code words that are found to be uncorrectable (erasures) are transmitted with a predetermined number of bits in place of the parity portion associated with those code words. These predetermined number of bits indicate the existence of the erasures, which can be reproduced for continued transmission to the final destination. By having the number of predetermined bits being less than the number of parity bits, the bandwidth requirement for wireline communication paths is reduced.
