41、ordination with ATIS T1E1.5 and T1E1.7. This joint Standard is published in accordance with the TIA Style Manual. Approval of Standard This Standard was approved by TIA/EIA Technical Committees TR-41, ATIS Committee T1 and the American National Standards Institute (ANSI). Contributing Organizations

42、During the development of the original Standard, subject matter experts were gathered under the auspices of the Electronic Industries Alliance / Telecommunications Industry Association (EIA/TIA) to determine the minimum commercial building grounding and bonding infrastructure necessary to support, f

43、rom a functional perspective, the variety of telecommunications equipment and systems found in many of todays commercial buildings. This Standard has been revised as an ongoing effort between TIA Engineering Committee TR 41, Environmental Considerations Technical Subcommittee TR 41.7, and the Allian

44、ce for Telecommunications Industry Solutions (ATIS), Committee T1, Technical Subcommittee T1E1, Power Systems Working Group T1E1.5 and Electrical Protection Working Group T1E1.7. Through this joint revision process, a broader telecommunications industry perspective has been achieved by bringing toge

45、ther telecommunications subject matter experts in the areas of central office and customer location grounding and bonding, representing manufacturers, users, and individuals active in other standards organizations. Documents Superceded This Standard replaces the first edition of ANSI/EIA/TIA 607, or

46、iginally published in August 1994. Significant technical changes and additions from the previous edition include: - Greater grounding busbar detail. - Tower and antenna grounding and bonding recommendations. - Work area and personal operator-type equipment position grounding and bonding recommendati

47、ons. - Revised, harmonized terminology. Terminology from the National Electrical Codeg210(NECg210) has been retained. There are five annexes to this Standard.
