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.
