2、s iiiance NOTICE TIA/EIA Engineering Standards and Publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining wi
3、th 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 TIA/EIA from manufacturing or selling products not conforming to such Standards and Publications, nor shall the existence of such Sta
4、ndards and Publications preclude their voluntary use by those other than TIA/EIA members, whether the standard is to be used either domestically or internationally. Standards and Publications are adopted by TIA/EIA in accordance with the American National Standards Institute (ANSI) patent policy. By
5、 such action, TIA/EIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Standard or Publication. Note: The users attention is called to the possibiliv that compliance with this document may require use of one or more inventions cove
6、red by patent rights. By publication of this standard, Interim Standard, or TSB, no position is taken with respect to the validity of those claims or of any patent rights in connection therewith. The patent holder(s) so far identified have, however, filed statements of willingness to grant licenses
7、under those rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to obtain such licenses. Details may be obtained from the standards developer. TIA/EIA INTERIM STANDARDS TIA/EIA Interim Standards contain information deemed to be of technical value to the industry, a
8、nd 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 TIA/EIA Standard. TIA/EIA Interim Standards should be reviewed on an annual basis by the formulating Com
9、mittee and a decision made on whether to proceed to develop a TIA/EIA Standard on this subject. TIA/EIA Interim Standards must be cancelled by the Committee and removed from the TIA/EIA Standards Catalog before the end of their third year of existence. Publication of this TIA/EIA Interim Standard fo
10、r trial use and comment has been approved by the Telecommunications Industry Association. Distribution of this TIA/EIA Interim Standard for comment shall not continue beyond 36 months from the date of publication. It is expected that following this 36 month period, this TIA/EIA Interim Standard, rev
11、ised as necessary, will be submitted to the American National Standards Institute for approval as an American National Standard. Suggestions for revision should be directed to: Standards it operates on a featureless octet stream, delivering the octets in the order received. IUP has procedures to sub
12、stantially reduce the error rate exhibited by CDMA traffic channels. There is no direct relationship between higher layer packets and the underlying traffic channel frames; a large packet may span multiple traffic channel frames, or a single traffic channel frame may contain all or part of several s
13、mall higher layer packets. Section 2 is a general description of IUP that defines its use by any service option for which it is suited. Section 3 defines the IUP procedures for encrypted or non-encrypted applications. Section 4 defines the IUP frame formats. Some features require capabilities first
