  • Why is A1,A2 bytes value chosen as F6, 28 Hex?

    From PRITHA BHATTACHARYA@21:1/5 to All on Sat Apr 13 04:54:08 2019
    Why was value of 1111 01110 and 0010 1000 chosen ? Any specific reason for the same ?

    I have already answered this question in 2008: https://groups.google.com/d/msg/comp.dcom.sdh-sonet/awEruI3uhOM/T2M2GLsho08J

    The value is the result of a study taking into account: length of
    frame alignment word, frame length, bit-error rate,

    More detailed information can be found in table 5.6 op page 104
    of the following book:

    Bylanski, P., and D. G. W. Ingram: "Digital Transmission Systems,"
    Institution of Electrical Engineers Telecommunication Series 4,
    Peregrinus, Stevenage, England, 1976.

    Best regards, Huub.
