XAUI Jitter Agenda 28th Febuary 2001



This week´s telco is rather busy. We will split the telco into three
parts, and see how far we get.

1) Status of Comments : Make sure what we known what we are doing at the
plenary

2) Email Traffic : Are these points covered by current comments, if not
are they critical?

3) Open Actions : Again, are these points covered by current comments,
if not are they critical?

(Please see attachment for details)

Please be punctual, and if your name is not included in the attendants
list (attached) please email me before hand.
