"NEBS Level 2", the second level of NEBS standard developed by Bell Labs for RBOC central office equipment, addresses equipment operability, but in a controlled environment. For example, equipment could be used in a data center, however, if the equipment performs non-critical operations it could be used under environmental extremes. Note that this level is very rarely used because it is ambiguous.
