Simple solution to terminate the discussion about SONET versus SDH

["Mannie, Eric" <Eric.Mannie@ebone.com>]

Dear All,

There is an easy way to stop definitively this discussion based on technical
facts:

Stephen, Juergen and Maarten, please tell us: today, are the frame
structures and all the bytes in the SDH and SONET overhead completely
identical, used and interpreted in the same way, is the monitoring exactly
the same ? In particular, if I provision and operate an SDH circuit/LSP is
this fully identical to a SONET circuit/LSP from *all* point of views ?

PLEASE ANSWER BY YES OR NO ONLY. Other explanations are not needed at this
stage.

If the answer is yes: SONET is totally identical to SDH.
If the answer is no: SONET is not the same as SDH.

I think that without that answer we cannot take any *technical* decision on
this mailing list and at the IETF.

Thanks to answer. 

Kind regards,

Eric
