All electronic equipment has the potential to interfere with other electronic equipment. Interference can be caused by electromagnetic radiation, the grounding system, the electrical power connection, excessive heat or blocking the natural airflow, and connecting wires or cables. The FCC (Federal Communications Commission) regulates a portion of this problem through Part 15 of their rules and regulations. Even more stringent than the FCC Part 15 requirements, Network Equipment Building Standards (NEBS) covers a large range of requirements including criteria for personnel safety, protection of property, and operational continuity. The documents cover both physical requirements including: Space Planning, Temperature, Humidity, Fire, Earthquake, Vibration, Transportation, Acoustical, Air Quality and Illumination; and electrical criteria including: Electrostatic Discharge (ESD), Electromagnetic Interference (EMI), Lightning and AC Power Fault, Steady State Power Induction, Corrosion, DC Potential Difference, Electrical Safety and Bonding and Grounding.

Network Equipment Building System. The Network Equipment Building System is a set of standards that, when used in reference to our racks and enclosures, specifies the method in which an enclosure is to be grounded and bonded.

Network Equipment Building Standards. A set of standards for equipment to be installed in telco central offices.

Network Equipment Building Systems. Adhering to standards from Bellcore for equipment used in Telco central offices (COs). It provides stringent specifications for durability, grounding, cables and hardware interfaces.

Network Equipment-Building System. Equipment standards set forth by Bell Communications Research (Bellcore) for electromagnetic compatibility, thermal robustness, fire resistance, earthquake and office vibration resistance, transportation and handling durability, acoustics and illumination, and airborne contaminant resistance.

Network Equipment Building Standards. A set of requirements for the reliability and usability of equipment, established by Bellcore.

Network Equipment Building Systems. A standard for switches and other equipment.

Network Equipment Building Standard was designed by the TELCO community to handle a number of problems associated with housing very expensive and delicate equipment. The NEBS specifications address many CO hazards from electrical shielding to powering to acts of God such as earthquakes and fires.

Network Equipment - Building System. A Telcordia (formerly, Bellcore) comprehensive set of telecommunications performance, quality, environmental, and safety requirements. NEBS standards include such diverse requirements as fire containability and extinguishability; ability to withstand earthquake, thermal, and mechanical shock; operating temperature ranges; and resistance to electro-static discharge (ESD).

Network Equipment Building Systems. A standard set of physical and electrical requirements for telecommunications equipment intended for installation in the telephone company central office environment. NEBS requirements are specified in various Bellcore documents.

Network Equipment Building Systems. In OSS, the Bellcore requirement for equipment deployed in a central office environment. Covers spatial, hardware, crafts person interface, thermal, fire resistance, handling and transportation, earthquake and vibration, airborne contaminants, grounding, acoustical noise, illumination, EMC, and ESD requirements.

Network Equipment-Building System. Criteria, as referenced in Bellcore SR-3580, designed to insure that equipment placed in the telephone network meets certain minimum standards.
