Please find below a response I received from Telecordia regarding GR-3028 and
what would be covered at the NEBS2001 Conference.

Here is the response from our SME on the GR-3028 question.
Modern telecommunications and data equipment consumes increasingly more
energy per unit volume due to miniaturization and higher clock speeds. Most
of this energy is subsequently released as heat to the surrounding
equipment space. Inadequate environmental design has the potential to
jeopardize multimillion-dollar investments in sophisticated equipment and
to interrupt a vast amount of revenue-generating services.
To ensure network reliability and longevity in today's evolving network
environment, Telcordia initiated in 2000 a new unique cross-industry effort
in thermal management in telecommunications facilities. Telcordia
initiative (Telcordia GR-3028) has attracted 21 major equipment vendors and
service providers as well as HVAC and chip manufacturers. The goal is to
develop a requirements document for thermal management in environmentally
controlled network facilities in general and in central offices in
particular. The document will provide needed standardization for ensuring
network integrity while leaving room for innovative equipment designs and
environmental solutions.
A well-developed "holistic" approach is required to understand today's
thermal management problem. Equipment cooling on one hand and space cooling
on the other cannot be viewed as two isolated parts of the overall thermal
challenge. Telcordia GR-3028 and its thermal management guidelines are
based on the understanding that equipment and equipment rooms need to be
better matched to ensure continued network reliability. While Telcordia
GR-63-CORE will continue to serve as the premier equipment-testing
document, GR-3028 will focus on the thermal equipment environment.
Magnus' presentation at the NEBS Forum will provide a high-level overview
of this Generic Requirements work. Details will be included in the GR-3028
document scheduled for release by late 2001.

Subject: RE: NEBS temp
Thank you for the responses I have gotten thus far. The responses I've
gotten is that the CO environment isn't as good as we would hope and the CO
environment can be frightenly worse than what Telcordia defines in their
standard.
As a follow up question...I have just stumbled across a new Telcordia
standard GR-3028. The little info I could find describes it as redefining
thermal criteria for CO systems.
Here's the small description by Telcordia:
GR-3028 Thermal Requirements
With Central Office equipment running faster and hotter than ever before,
are you ready to handle the radical temperature changes? NEBS 2001 is the
only place you'll get to review information now on this soon-to-be-released
requirement.
Anybody got some preliminary insight into this new standard?
Thanks.
