What is NEBS Level 3?
Network Equipment Building System (NEBS) standards
set requirements for telco equipment. The standards are
maintained by Telcordia Technologies, Inc., formerly Bellcore.
Bellcore Special Report, SR-3580 defines three distinct
functional levels of NEBS compliance. The third of these
levels, NEBS Level 3, is the most stringent, certifying carrier-
class equipment intended for long-term use in variable
environments.
NEBS Level 3 certifies that a piece of equipment can be
safely used in an extreme environment. To become certified
at NEBS Level 3, a device must meet strict physical, electrical,
and environmental requirements to prove it will operate
safely and reliably in extreme conditions. It must pass a series
of tests that include extreme heat, humidity, fire, earthquakes
(Zone 4), light, and noise.
