Hi Fatai,

I believe there is an error in RFC 7139 regarding the ITU-T definitions regarding ODUflex(CBR) in Table 1.

Table 1 lists the minimum, nominal and maximum values for the TS.  But the left column is wrong.  Per G.709 (Table 7-7) these values should be listed as ODTUk.ts (ODTU2.ts, ODTU3.ts, ODTU4.ts).  Note that the formulas in this section are written correctly (e.g., refers to ODTUk.ts)

Table 2 for ODUflex(GFP) is correctly referring to ODUk.ts, but I wanted to point out the the values for ODUk.ts are different than ODTUk.ts used for ODUflex(CBR). ODUk.ts is given in G.709 Table 7-8.  You may want to explicitly show the ODUk.ts values to be consistent with ODUflex(CBR), although this update is not absolutely necessary as the text is correct.
