NEBS Testing

NEBS Testing

NEBS (Network Equipment Building System) testing is a requirement for telecom equipment to be deployed in central office facilities, customer premises and outside plant facilities. Telecom service providers require the tests to ensure network integrity and continuous operation of the network. The standards most commonly required are the Telcordia GR-1089 CORE and GR-63 CORE.

Curtis-Straus offers knowledgeable testing to these standards for all U.S. telecom service providers.
