2. What is ETSI? ETSI is the European Telecommunications
Standards Institute, which establishes the telecommunications
standards in Europe. 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
