Hi Xian,
I have noticed that in revision 02 of the LMP draft, OTU2e was defined as a HO-ODU with a value of 5 under OD(T)UK, but on rev 06 of this draft this has been removed, but  "Flag F" corresponding to ODU2e as a LO-ODU is still in rev 6.

Version 2:
OD(T)Uk field     Signal type of HO ODUk or OTUk
   -------------     ------------------------------
      0              Reserved (for future use)
      1              HO ODU1 or OTU1
      2              HO ODU2 or OTU2
      3              HO ODU3 or OTU3
      4              HO ODU4 or OTU4
      5              OTU2e
      6              OTU3e1
      7              OTU3e2
      8-15           Reserved (for future use)

Version 6:
OD(T)Uk field     Signal type of HO ODUk or OTUk
   -------------     ------------------------------
      0              Reserved (for future use)
      1              HO ODU1 or OTU1
      2              HO ODU2 or OTU2
      3              HO ODU3 or OTU3
      4              HO ODU4 or OTU4
      5-15           Reserved (for future use)

Can you please help me understand why OTU2e was removed from OD(T)UK?

If we have a link that supports OTU2e and allows a 11.095 rate, what should go in ODU(T)UK?

Thanks,
Ladan
