Network Equipment Building System

from Wikipedia, the free encyclopedia

NEBS (Network Equipment-Building System) is an American industrial standard that determines the approval of telecommunication devices and their peripherals in the telephone, data and cellular networks of the RBOCs (Regional Bell Operating Companies). The scope of NEBS includes EMC and environmental tests, as well as safety tests, and is largely determined by the test standards of Telcordia GR-63-CORE and GR-1089-CORE. Although NEBS is not the legal requirement of the US authorities, it is nevertheless required as a strict industry standard by the TCG (Telecom Carriers Group), which includes the telecommunications companies Verizon , AT&T and Qwest .

NEBS test laboratories

The NEBS tests must be performed by test laboratories that are either approved in the USA as NRTL (Nationally Recognized Test Laboratory) or are certified outside the USA by a public accreditation body with ISO / IEC 17025. Verizon is the strictest member of the TCG in this context and also insists on an ITL (Independent Test Laboratory) award. There are currently 11 testing laboratories in the US and one testing laboratory in Europe (NTS Europe GmbH in Munich, Germany) that are approved under the Verizon ITL NEBS program. An extensive list of the test laboratories accepted by Verizon can be found on the web links.
