interfaces to meet the requirements of GR, Issue 6. GR Issue 6 Summary Let’s begin with a brief overview of the standard. Issue 6 contains ten chapters: 1) Introduction 2) System-Level ESD and EFT 3) EMI 4) Lightning and Power Fault 5) Steady-State Power Induction 6) DC Potential Difference 7) Electrical and Optical Safety Criteria. Telecordia GR – (formerly Bellcore) sets the criteria for wireline and wireless EMC applications. GR is used to ensure telecommunications equipment contains the Electromagnetic Compatibility (EMC) and electrical safety criteria necessary to perform safely and reliably. GR and is not a comprehensive review of the entire document. By providing a focus on ESD, surge, and power fault testing, Littelfuse is intending to demonstrate the application’s need for Littelfuse type protection components to comply with these specific test requirements.
