    ORDERING INFORMATION

    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
      MHz

    • 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
      figures

    • New lightning requirements for equipment at cell sites

    • Simplified requirements and testing for compatibility of equipment dc power ports


    About GR-1089

    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
    environment.

    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.
