Re: [10GBASE-T] Proposed modification to PAR scope
Horizontal cabling (structured) applies to data centers.
The TR42 Telecommunications Infrastructure Standard
for Data Centers currently in industry ballot expands
the current (TIA/EIA) horizontal cabling definition
in order to address data center horizontal cabling topologies.
PN-3-0092 (to become TIA/EIA–942) Telecommunications Infrastructure Standard
for Data Centers
2.2 Definition of terms
horizontal cabling: 1) The cabling between and including the
outlet/connector and the horizontal cross-connect. 2) The cabling between and
building automation system outlet or the first mechanical termination of the
point and the horizontal cross-connect. 3) in a data center, horizontal
cabling is the cabling from
the horizontal cross-connect (in the main distribution area or horizontal
distribution area) to the
outlet in the equipment distribution area or zone distribution area.

<< I agree that "on horizontal structured cabling" probably needs a tweak. It
could possibly be interpreted as requiring 100 m operation for all supported
media. As Terry points out, it doesn't really reflect the data center as a
focus of broad market potential.
