Abstract
A system receives input data frames that are configured according to a SONET or an SDH standard. The input data is converted to parallel data. The system provides groups of bits along parallel signal lines. In each group of bits, N contiguous bits in the group form a complete word of input data. The system identifies the boundary between complete words in the input data by comparing subsets of the bits to predefined framing patterns. The system then aligns the input data based on the location of each word using the boundary information. The output data of the system includes data that is word aligned. The system can also detect boundaries between the frames.
