    ORDERING INFORMATION

    ABSTRACT: GR-1217 contains proposed, generic physical design requirements for separable connector products used in a typical service provider
    network. The generic requirements defined in this NEBS (Network-Equipment Building System) document apply to separable electrical
    connectors used in typical service providers' electronic telecommunications networks. The scope includes Printed Wiring Board (PWB)
    connectors, coaxial and cable connectors of various types, and IC sockets. It includes connectors made with noble and non-noble metal
    contact finishes. However, these requirements do not apply to non-metallic optical connectors used for mating of fiber optics or to
    connectors intended for AC power applications. The pin and socket connector, widely used by equipment manufacturers to interface PWB
    assemblies to backplanes in current telecommunications systems, is the most prominent and the most critical application within this
    scope. Edge-card connectors with plated contact fingers are also included in the PWB classification.

    This NEBS document expands and enhances the separable electrical connector requirements found in GR-78. Quality and reliability
    aspects for separable connectors as components detailed in GR-357 are also included. Where there is a discrepancy between
    requirements in this document and requirements in these two more general documents, the requirements here take precedence.

    GR-1217 meets all quality level standards for electrical connectors, plus:
    • Provides a comprehensive treatment of electrical connector performance for telecommunications hardware and addresses both noble
      and non-noble plated connectors

    • Includes a flexible qualification methodology, which allows for cutting-edge product innovations to be qualified and used in
      telecommunications products

    • Emphasizes connector performance via qualification tests, as opposed to preferred metallizations; connector performance metrics
      were reviewed and modified where appropriate to account for reduced connectors geometrics now typically employed

    • Defines accelerated aging test methods, which can be used to determine reliability of mean time between failures of a particular
      connector

    • Aligns with GR-63 and GR-78.

    This document replaces TR-NWT-001217.

    Issue 2 of GR-1217-CORE, Generic Requirements for Separable Electrical Connectors Used in Telecommunications Hardware,
    replaces Issue 1.

    When using GR-1217, you may need to refer to GR-63, GR-78, GR-357, and SR-332, as well as various ANSI, ASTM, MIL
    and UL standards.
