A number of people have
sent me email asking about channel models. The channel model formulas are in the
presentation up on the reflector at:
http://www.ieee802.org/3/an/public/mar04/kasturia_2_0304.pdf These will be superseded by the actual link segment text when that is approved. An unapproved draft of this is available online at: http://www.ieee802.org/3/an/public/may04/clause%2055-Link%20Segment-release.pdf As for actual complex
(phase magnitude models) that reflect cabling that meets the various models, we
need measurements that are then scaled to meet the formulas.
Chris DiMinico has one
set of measurements via the cabling Adhoc and I am forwarding his email on that
with his attachments to the reflector. Scaled versions of these together with
scaled versions from a few other measurements done by some cabling vendors will
be put on the website soon.
Questions on this
data can be directed to Chris DiMinico

As we discussed; please find attached the cabling ad hoc measurement data
for a 100 meter
four connector topology. I labeled the current models
used from the measurment
data set (unscaled). The Category 6 adhoc models are posted on the
IEEE reflector (http://grouper.ieee.org/groups/802/3/an/public/material/10GBASE-T_Cat6_Model.zip).

Regards,
Chris
