White Paper: Successful Design and Test Methodology for NEBS - Creating
Equipment that Meets Carrier Requirements using Open Standards

Network Equipment Building System (NEBS) requirements are defined in Telcordia SR- 3580 and primarily consist of compliance to Telcordia GR-63-CORE and GR-1089-CORE. NEBS certification is required by North American Regional Bell Operating Companies (RBOC), Competitive Local Exchange Carriers (CLEC), International Exchange Carriers (IXC), and other networks operators prior to deployment in their networks.

In addition to meeting NEBS requirements, some of the North American carriers require additional testing to be performed, most commonly known as “NEBS Supplementary Requirements”.

European carriers generally require proof of compliance to a similar set of standards generated and maintained by the European Telecommunications Standards Institute (ETSI). These standards are primarily EN 300 019, EN 300 386, ETS 300 753 and EN 300 132. While the requirements are very similar to NEBS, the limits and specific tests may vary based on the differences in climate and geography between the U.S.A. and Europe.
