Generic Requirements for Assuring the Reliability of Components Used in Telecommunications Equipment
Document Number GR-357
Issue Number 01
Issue Date Mar 2001
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
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
