Abstract:
1. An apparatus for deskewing members of a virtual concatenated group (VCG) in a synchronous optical network/synchronous digital hierarchy (SONET/SDH) signal, comprising: write logic coupled to a SONET/SDH signal source and to first and second memory means, the write logic storing in the first memory means data from a SONET/SDH signal generated by the SONET/SDH signal source, and the write logic storing in the second memory means frame status of members of a virtual concatenated group (VCG) in the SONET/SDH signal generated by the SONET/SDH signal source; first read logic coupled to said first and second memory means, wherein said first read logic reads data from said first memory means based on frame status read from said second memory means and outputs deskewed data; third memory means coupled to said first read logic for temporarily storing the deskewed data output by the first read logic; and second read logic coupled to said third memory means, wherein said second read logic reads data from said third memory means in accordance with a select one of a number of selectable operational modes that read data from said third memory means at different rates, said different rates dictated by data of said SONET/SDH signal generated by the SONET/SDH signal source.
