1、TIAIEIA INTERIM STANDARD Data Service Options for Wideband Spread Spectrum Systems TIA/EIA/IS-707-A (Revision of TIA/EIA/IS707) APRIL 1999 TELECOMMUNICATIONS INDUSTRY ASSOCIATION Electronic Industries Alliance NOTICE TIAEIA Engineering Standards and Publications are designed to serve the public inte

2、rest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement 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 Publicat

3、ions 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 Standards and Publications preclude their voluntary use by those other than TIAEIA members, whether the

4、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 such action, TIAEIA does not assume any liability to any patent owner, nor does it assume any obligat

5、ion whatever to parties adopting the Standard or Publication. TIA/EIA INTERIM STANDARDS TIA/EIA Interim Standards contain information deemed to be of technical value to the industry, and are published at the request of the originating Committee without necessarily following the rigorous public revie

6、w and resolution of comments which is a procedural part of the development of a TLARIA Standard. TIAEIA Interim Standards should be reviewed on an annual basis by the formulating Committee and a decision made on whether to proceed to develop a TIA/EIA Standard on this subject. TIAEIA Interim Standar

7、ds 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 for trial use and comment has been approved by the Telecommunications Industry Association. Distribution of this TIAEIA I

8、nterim Standard for comme: 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, revised as necessary, will be submitted to the American National Standards Institute for approval as an American National St

9、andard. Suggestions for revision should be directed to: Standards that a certain course of action is preferred but not necessarily required; or that (in the negative form) that a certain possibility or course of action is discouraged but not prohibited. May and may not indicate a course of action pe

Because o

24、f this, 4 there may be stylistic inconsistencies between some of the chapters in the standard. 5 6 7 8 9 10 11 12 In particular, in TIA/EIA/IS-707-A, the editor has used the automatic table and figure numbering capabilities of the word processing software in the new chapters. This allows automatic u

25、pdate of references to those tables and figures without manual intervention. The editor has also used the ability of the word processing software to automatically begin a major section on an odd page. This may cause the word processing software to produce a blank page before the major section, when

26、the previous sections text ends on an odd page. However, it allows text insertion and deletion without requiring corresponding manual insertion or deletion of manually produced blank pages preceding a major section. 13 1-4 ! 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 2 NETWORK REFERENC

A Service Option is composed of three fields, the Proprietary Indicator, the Service Option Revision, and the Base Service Option Number (see TSB58), as shown in Figure 3. l. 1-1. The base data service (e.g fax) is identified by the Base Service Option Number. The

37、data service feature set is identified by the Service Option Revision. The first feature set for any base data service is assigned Service Option Revision O, the next is assigned Service Option Revision 1, and so on, up to Service Option Revision 7. 11 Service Option Proprietary Base Service Service
