Service Option
12、 4 and Service Option 5 conform to the general requirements for service options specified in TIA/EIA/IS-95-A. A mobile station operating in wideband spread spectrum (CDMA) mode conforming with TIA/EIA/IS-95-A and this standard can obtain asynchronous data service and digital Group-3 facsimile servic
13、e in any cellular system conforming with these standards. This standard does not address the quality or reliability of Service Option 4 and Service Option 5, nor does it cover equipment performance or measurement procedures. Additional data services may be incorporated into future revisions of this
14、standard. SECTION SUMMARY 1. 2. 3. 4. 5. Introduction. This section defines the terms, references, and network reference model used in this document. Recommendations for the Rm Interface. This section describes the recommendations for the interface between terminal equipment and a mobile station. Re
15、quirements for the Um Interface. This section defines the requirements for the interface between a mobile station and a base station. Recommendations for the Ai Interface. This section describes the recommendations for the data protocol standards to be used on the interface between the base station
16、and the public switched telephone network. AT Command Processing. This section defines the requirements for the processing of AT commands. Appendix A. Modified Nordstrom-Robinson Code. This appendix presents a table with the modified Nordstrom-Robinson code used to protect 1/8 rate RLP frames. NOTES
17、 1. 2. 3. The following verbal forms are used: “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 not“ indicate that one of several possibilities is recommended as particularly suitable, witho
18、ut mentioning or excluding others: 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 “need not“ indicate a course of action permissible within the limit
19、s 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 clanfy items discussed in the body of the specification. Unless indicated otherwise, th
20、is document presents numbers in decimal form. Page ii TIA/EIA/IS-99 Binary numbers are distinguished 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 x i
21、s used to represent a binary bit of unspecified value. For example xxx00010 represents any 8-bit binary 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 di
22、gits. For example, Ox2fal represents a number whose binary value is O0 1 O 1 1 1 1 1 O 1 O000 1 and whose decimal 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 represent

48、mission capability on TIA/EIA/IS-95-A wideband spread-spectrum cellular systems using the protocols and procedures defined herein. Service Option 5 provides Group-3 facsimile (abbreviated as “fax“ hereafter) transmission capability for these systems. These two Service Options are defrned in a single
49、 standard because their user interfaces and associated call control procedures are similar. This parallels the current trend in analog modems, which commonly provide both fax and async data services through the same modem unit. 1.2 Terms AT Command Set.
