Probably the wrong question Bill.
The public utilities have lots of exemptions to the various codes -
electrical, fire, FCC etc. But to keep them they also have to continuously
prove they are meeting or exceeding those requirements - just in their own
fashion.
Fire for example. They save many bucks in CO's by not having sprinkler
systems. However, as part of the NEBS qualification they will require you to
set a sample of your equipment on fire, and then monitor flame - and in
Verizon's case smoke abatement. If the equipment can't burn or propagate
fire - there is no need for sprinklers or so goes the logic.
Another example is the FCC emissions regulations. Basically, they
are exempt in their central offices. The equipment doesn't have to be
compliant - but they will have to prevent it from becoming a problem outside
of their offices. I've heard tails of building screen rooms inside existing
structures to contain noise when a neighbor complained. I can't document
this by the way - more of a beer with the RBOC's types discussion at a
recent NEBS conference. To solve this, even though they have an exemption,
you'll see that they require emissions test that at least for part of the
frequency range, mimics the FCC regulations. In fact you would be slightly
nuts not to have an accredited EMC and NEBS lab give your both reports at
the same time.
Again none of this is to imply that they don't meet the codes or the
intent of the codes, its just that they are just allowed a lot more self
monitoring, if you will.
So the real question is if they have an exemption to a specific
standard, law, or clause what will they expect of you or your equipment to
maintain that exemption. They are they likely to grant you the same
exemption unless nobody else can solve the problem and you are the only
vendor that can supply what they need.
I've taken a little liberty with my generalization mind you.

Subject: NEC codes and the CO
Does the NEC code apply to the Central Office?
I see section 90-2 (b) # 4 where NEC may not apply.
I welcome your comments.
Thank you.
