Actually,
I have a question for Qi and maybe Vlad: For some reason, I still keep VDSL system requirements addendum document in T1E1.4 by TS's preference.
Vlad, I think the new noise models have to go in that, but Qi, there were some other things in the August meeting
that I am supposed to put in the document (it was deferred presentation to December, so I will R1 it and present in Florida instead) - can you remember what
they were? Also, no sense you and I overlapping on presentation - so please advise as to how we can make efficient use of time. I should not be doing same things
you are.
I do not want this VDSL SR editorship to get in the way of any CAP/DMT fight and just want to do it for best interests of all, which is why I write here.
As SR-alone editor, I can manage that without causing bias
- of course, Qi needs to do any more formal VDSL document because everyone knows where I stand on line code so its best for me not to do that while there is no decision in the VDSL area because I would necessarily bias it and write a DMT standard if I were editor!
There is probably a good split of work here somewhere and if you two know and agree, we're not likely to have any problems.
Best Regards,
John C.
