1、The Teleconmiunications Industry Association represents the conmiunications sector of NOTICE TIAIEIA Engineering Standards and Publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improv
2、ement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular need. Existence of such Standards and Publications shall not in any respect preclude any member or nonmember of TIAIEIA from manufacturing or selling products not confor
3、ming to such Standards and Publications, nor shall the existence of such Standards and Publications preclude their voluntary use by those other than TIAIEIA members, whether the standard is to be used either domestically or internationally. Standards and Publications are adopted by TIAIEIA in accord
4、ance with the American National Standards Institute (ANSI) patent policy. By such action, TIAIEIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Standard or Publication. TIA STANDARDS TIA Standards contain information deemed to b
5、e of technical 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 TIAIEIA Standard. TIA Standards should be reviewed on an annual b
6、asis by the formulating Committee and a decision made on whether to proceed to develop a TIAIEIA Standard on this subject. TIA Standards must be cancelled by the Committee and removed from the TIAIEIA Standards Catalog before the end of their third year of existence. Publication of this TIA Standard
7、 for trial use and comment has been approved by the Telecommunications Industry Association. Distribution of this TIA Standard for comment shall not continue beyond 60 months from the date of publication. It is expected that following this 36 month period, this TIA Standard, revised as necessary, wi
8、ll be submitted to the American National Standards Institute for approval as an American National Standard. Suggestions for revision should be directed to: Standards December 1997. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43
