Replaces TR-NWT-000357 Issue02

    ABSTRACT: In the manufacturing of telecommunications equipment, the proper selection and application of electrical components is the responsibility of the manufacturer and its design and component engineering organizations. In its interactions with manufacturers, however, Telcordia has found that component selection, qualification, and lot acceptance practices vary widely. Recognizing that good component reliability is essential for good equipment reliability, Telcordia, in this GR-357, has defined a set of NEBS (Network Equipment-Building System) requirements that, in the view of Telcordia, are reasonable and would help ensure satisfactory device reliability in a manufacturer's products.

    This NEBS document covers components of all types used in the manufacture of telecommunications hardware purchased by telecommunications service providers, including silicon and gallium arsenide integrated circuits, and discrete and passive devices. A basic premise is that component reliability is best assured by the equipment manufacturer through component and component manufacturer qualification, lot-to-lot quality and reliability controls, proper storage and handling, adequate documentation, and feedback and corrective action.

    This document, which contains the Telcordia view of generic requirements for assuring the reliability of components used in telecommunications equipment, replaces TR-NWT-000357.

    When using GR-357, you may need to refer to GR-63, GR-78, SR-332, GR-468, TR-NWT-000870, TR-NWT-000930, GR-1221, GR-929, UL 94, and various MIL-STD, IEC, and ANSI documents. You may also want to refer to GR-326, and/or GR-1217.
