3、en manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for their particular need. The existence of such Publications shall not in any respect preclude any member or non
4、-member of TIA from manufacturing or selling products not conforming to such Publications. Neither shall the existence of such Documents preclude their voluntary use by non-TIA members, either domestically or internationally. TIA DOCUMENTS TIA Documents contain information deemed to be of technical
5、value to the industry, and are published at the request of the originating Committee without necessarily following the rigorous public review and resolution of comments which is a procedural part of the development of a American National Standard (ANS). Further details of the development process are
6、 available in the TIA Engineering Manual, located at http:/www.tiaonline.org/standards/sfg/engineering_manual.cfm TIA Documents shall be reviewed on a five year cycle by the formulating Committee and a decision made on whether to reaffirm, revise, withdraw, or proceed to develop an American National
7、 Standard on this subject. Suggestions for revision should be directed to: Standards & Technology Department, Telecommunications Industry Association, 2500 Wilson Boulevard, Arlington, VA 22201 U.S.A.

OVERVIEW FOR TIA-470-C STANDARDS 1 The TIA-470-C sub-documents are the result of the revision process for the TIA-470-B document. 2 Due to the size of the TIA-470-B
32、document it was deemed necessary to separate the revised standard 3 into smaller sections to allow for greater attention to detail. The TIA-470-C document is formed as a 4 series of sub-documents. TIA-470-B will be rescinded when the existing requirements in TIA-470-B 5 have been published as TIA-47
33、0-C sub-documents. 6 7 The TIA-470-C structure is provided in the “Document Structure for TIA-470-C” clause of this 8 document. The new structure provides improved document flexibility, allowing revisions of each 9 particular Section to be handled in a more efficient process. This enables additional
34、 requirements to 10 be developed and placed into the new document structure without having the entire document revised. 11 12 The TIA-470-B document format underwent significant changes. Wherever possible, specific test 13 methods have been removed in favor of more generalized methodologies and spec
35、ific schematics for 14 test circuits have been replaced with generalized circuits, specifying the test circuit performance. 15 16 Copyright Telecommunications Industry Association Provided by IHS under license with EIANot for ResaleNo reproduction or networking permitted without license from IHS-,-,
