Re: [10GBASE-T] Proposed modification to PAR scope





Pat,

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 
telecommunications
outlet/connector and the horizontal cross-connect. 2) The cabling between and 
including the 
building automation system outlet or the first mechanical termination of the 
horizontal connection 
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.

Regards,

Chris

<< 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.
