  • What is the sequence of transmission of OTN/SONET frame structure

    From PRITHA BHATTACHARYA@21:1/5 to All on Wed Feb 27 22:31:21 2019
    OTN frame has overhead bites and payload bytes. I have read that frame transmission happens byte wise from left to right and then top to bottom .

    Can someone please let me know the sequence. Is it that row 1 bytes 1 to 4080 is transmitted first and then row 2 bytes ? Or first all 4 rows of overhead is transmitted from left, followed by payload ?

    row 2 bytes?

    This is correct:
    per row 16 bytes overhead, 3808 bytes payload, 256 bytes FEC.

    Or first all 4 rows of overhead is transmitted from
    left, followed by payload?

    This is incorrect.

    It is all described in the standards: ITU-T Recommendation G.709.
    Especially figure 11-2.

    FREE to download from the ITU-T site.

    Best regards, Huub.
