Abstract
A data format conversion method and apparatus are presented to convert time-slot interleaved SONET/SDH data to per time-slot data for virtual concatenation processing. The converter consists of an input buffer and a matrix transposer. The input buffer discards the overhead and fixed stuff bytes of each SPE that it receives, while the matrix transposer packs the N payload bytes into N-byte words with alignment to a start-of-frame indicator. Because each N-byte word is associated with a different time slot, the N-byte words form per time-slot data.
