If one digs a bit into the NEBS requirement they call out approval to 60950-1 - or at least use to call it out. Then they add lots of other stuff environmental - earthquakes protection, corrosive gasses et al. Joe's correct it's a purchase specification not a regulatory requirement. But that makes it's at bit more restrictive in many ways. Especially when they require specific labs do the tests, and that list didn't include NIST labs a few years ago, so you might have to repeat the EMC to satisfy Verizon for example.

Hi Ken: The Telcordia NEBS requirements are not regulatory requirements, although they often get lumped into lists of "regulatory" requirements. The NEBS requirements are really just a purchase specification that any customer can impose on a list of requirements. Typically, the only customers who impose NEBS requirements are telecom carriers such as Verizon, AT&T, and Centurylink.
