NEBS Testing
Intertek is a Verizon-certified Independent Testing Laboratory (ITL), providing testing at our state-of-the-art Network Equipment Building System (NEBS) testing laboratories. We test to multiple requirements, including GR-63-CORE and GR-1089-CORE.
We are also approved by Verizon to offer NEBS witness testing services at Verizon approved vendors' test facilities. NEBS requirements cover equipment that is intended to go into the Central Office assuring that the Central office equipment will demonstrate compatibility but will not jeopardize network integrity.
NEBS requirements can vary depending on which of the telecom service providers you will be selling your equipment to. Many of the service provider specific requirements are based on the NEBS requirements included in GR-63-CORE and GR-1089-CORE. However, some service providers may require additional testing above and beyond the NEBS requirements.
The Telecommunications Carrier Group (TCG), a group formed to provide information to manufacturers and help synchronize NEBS testing across the industry, has developed a NEBS Compliance Checklist. In it, specifications, objectives and requirements are outlined to help manufacturers through the compliance process. You can view this document at either of these web sites:
