1. What is
NEBS?
NEBS
is an acronym for Network Equipment Building System. NEBS
has established requirements also known as “NEBS criteria.” NEBS
testing is required for vendors that sell networking products
to Competitive Local Exchange Carriers (CLECs) and Incumbent
Local Exchange Carriers (ILECs).

2. What
is ETSI?
ETSI
is the European Telecommunications Standards Institute,
which establishes the telecommunications standards in Europe.
Top
3. Why
is NEBS and ETSI testing important?
An
electronic device is capable of interfering with other
electronic devices through connecting wires, due to high
temperature conditions, electromagnetic radiation, and/or
grounding system.
In
the telecommunications world, networking equipment is heavily
used in central office environments. In this space, it
is critical to utilize networking equipment, which is mission-critical,
highly-reliable, and does not cause any interference.
NEBS
testing proves whether the networking equipment qualifies
for these mission-critical applications and guarantees
that the equipment will perform safe and flawless operation.

4. What
is NEBS testing based on?
NEBS
testing is based on the Telcordia (Bellcore) standard reliability
testing methods.

5. What
does NEBS Level 3 Certified mean?
NEBS
has three levels, Level 1, Level 2, and Level 3. Level
1 refers to cases where minimum compatibility with the
environment is needed. Level 2 applies for limited operability
of the product.
Finally,
NEBS Level 3 certification guarantees the maximum operability
of the equipment. It also certifies that the equipment
will perform well in harsh environmental conditions and
will not interfere with other electronic devices around.
NEBS Level 3 certified networking equipment is vital in
mission-critical applications.
