3、b322b 197 NOTICE W E i A 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
4、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 W E i A f r o m manufacturing or selling products not conforming to such Standards and Publications, nor shall the existence of such
5、Standards and Pubiications preclude their voluntary use by those other than TIA/ELA members, whether the standard is to be used either domestically or internationally. Standards and Publications are adopted by W E i A in accordance with the American National Standards institute (ANSI) patent policy.
6、 By such action, W E i A does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Standard or Publication. This Standard does not purport to address ali safety problems associate w i t h its use or all applicable regulatory requirements. I
7、t is the responsibility of the user of this Standard to establish appropriate safety and heaith practices and to determine the applicability of regulatory limitations before its use.

11、uirements form a standard for Service Option 1, a variable rate, two-way speech service option. Service Option 1 conforms to the general requirements for service options specified in TIA/ ELA/IS-95 “Mobile Station-Base Station compatibility Standard for Dual-Mode Wideband Spread Spectrum Cellular Sy
12、stem,” and in ANSI J-STD-008 “Personal Station-Base Station Compatibility Requirements for 1.8 to 2.0 Ghz Code Division Multiple Access (CDMA) Personal Communication Systems”. A mobile station operating in wideband spread spectrum (CDMAJ mode conforming with TIA/EIA/IS-95 and this standard can ob- t
13、 a i n speech service in any system conforming with these standards. This standard does not address the quaiity or reliability of Service Option 1, nor does it cover equipment performance or measurement procedures. SECTION SUMMARY 1 . General. This section defines the terms and numeric indicators us
14、ed in this document. 2. Service Option 1 : Variable Data Rate Two Way Voice. This section describes the requirements for SeMce Option 1. Included in these requirements is the description of a speech codec algorithm for variable rate, two-way voice. 1. 2. 3. 4. NOTES TIA/EIA/IS- 125, “Recommended Min
15、imum Performance Standard for Wideband Spread Spectrum Digitai Cellular System Speech Service Options,” provides specifications and measurement methods for equipment designed to provide Service Option 1. “Base station” refers to the functions performed on the land side, which are typicaily distribut
16、ed among a cell, a sector of a cell, and a mobile or personal communications switching center. Section 2 uses the following verbal forms: “Shall” and “shall not” identify requirements to be followed strictly to conform to the standard and from which no deviation is permitted. “Should” and “should no
17、t” indicate that one of several possibilities is recommended as particularly suitable, without mentioning or excluding others; that a certain course of action is preferred but not necessarily required; or that (in the negative form) a certain possibility or course of action is discouraged but not pr
18、ohibited. “May“ and “need not” indicate a course of action permissible within the limits of the standard. “Can” and “cannot” are used for statements of possibility and capability, whether material, physical, or causal. Footnotes appear at various points in this specification to elaborate and further
19、 clar items discussed in the body of the specification. i Copyright Telecommunications Industry Association Provided by IHS under license with EIALicensee=IHS Employees/1111111001, User=Wing, Bernie Not for Resale, 03/28/2007 23:22:35 MDTNo reproduction or networking permitted without license from I

Unless indicated otherwise, this document presents numbers in decimal form. Binary numbers are distinguished
21、in the text by the use of single quotation marks. In some tables, binary values may appear without single quotation marks if table notation clearly specifies that values are binary. The character k is used to represent a binary bit of unspecified value. For example XXXOOO 10 represents any 3-bit bin
22、ary value such that the least significant five bits equal 00010. Hexadecimal numbers (base 16) are distinguished in the text by use of the form Oxh. h where h .h represents a string of hexadecimal digits. For example, Ox2fal represents a number whose binary value is 101 11 110 100001 and whose decim
23、al value is 913. Note that the exact number of bits in the binary representation of a hexadecimal number strictly depends on the implementation requirements for the variable being represented. The following conventions apply to mathematical expressions in this standard: Lrd indicates the largest int
