Electromagnetic Compatibility and Electrical Safety - Generic Criteria for Network Telecommunications Equipment
Document Number GR-1089
Issue Number 06
Issue Date May 2011
Replaces TA-NWT-001089 Issue02
ABSTRACT: Contains Criteria for Wireline and Wireless EMC Applications
For over 25 years, GR-1089 has been used to ensure telecommunications equipment contained the Electromagnetic Compatibility (EMC)
and electrical safety criteria necessary to perform safely and reliably.
This all new issue of GR-1089 has NEBS criteria that cover equipment in Central Offices (COs); equipment in the Outside Plant (OSP)
at locations such as Controlled Environmental Vaults (CEVs), Electronic Equipment Enclosures (EEEs), and huts; equipment in
uncontrolled structures such as cabinets; and network equipment at the customer premises.
What's New in Issue 6?
- A new Appendix on Wireless applications
- EMI radiated and magnetic emissions requirements in Section 3 have been revised to eliminate testing at frequencies below 30
- Lightning and Power Fault criteria in Section 4 includes major revisions to simplify and condense this information
- Steady-State Power Induction Criteria in Section 5 also had major updates. This section contains several new and revised
- New lightning requirements for equipment at cell sites
- Simplified requirements and testing for compatibility of equipment dc power ports
Telecommunications equipment, by nature of its application in the telecommunications network, may be exposed to one or more sources
of electromagnetic energy. The criteria in this document are intended to help avoid equipment damage and malfunction because of
lightning, 50/60-Hz commercial power fault conditions, Electrostatic Discharge (ESD), Electrical Fast Transient (EFT), Electromagnetic
Interference (EMI), operation in the presence of a dc potential difference, and operation in a steady-state induced voltage
This document also presents other criteria intended to help establish that equipment will not become a fire or electrical safety
hazard in the presence of severe lightning or power fault conditions. Safe voltage levels for intentionally applied sources,
electrochemical corrosion effects, grounding, and dc powering are considered as well.
In addition to wireline services, this standard applies to wireless systems that provide fixed and/or mobile services that are
installed in locations with telecommunications network equipment or information technology networking equipment.
Issue 6 of GR-1089, Electromagnetic Compatibility and Electrical Safety - Generic Criteria for Network Telecommunications
Equipment, replaces Issue 5, and is a module of FD-NEBS-01, FR-ENGINEER-POWER-01, FR-NEBS-EQUIP-PROTECT-01,
FR-TRANSPORT-SYSTEMS-01, FR-SWITCHING-SYSTEMS-01 and FR-OUTSIDE-PLANT-01.
BONUS - FREE DOCUMENT!!!!!!
FD-NEBS-01 includes a free Roadmap to NEBS guide that lists and describes all NEBS-related documents, and the NEBS program.
GR-1089, Issue 6, is a companion document to GR-63 NEBS Requirements: Physical Protection.
