INTRODUCTION AND SERVICE GUIDE

General Description

This standard describes data services available on spread spectrum systems. It is organized into a series of related recommendations, some of which address functions common to all CDMA data services, and others which describe specific data service.

A recommendation may be referred to by its Interim Standard (IS) designation (e.g., IS-707- A. 1) or by its relative chapter number (e.g., Chapter 1 means IS-707-A. 1, Chapter 2 means IS-707-A.2, etc.).

This chapter provides an overview of the document's content, describes the simplified network reference model applicable to data services, introduces the data services, and discusses intersystem support for data services. Chapter 2 defines the Radio Link Protocol used by some data services to transport octets between the mobile station (MS)and BS/MSC. Chapter 3 is concerned with AT Command processing and the Rm interface. Chapter 4 defines asynchronous( hereafter called async) data service and Group-3 facsimile (hereafter called fax) service. Chapter 5 details a packet data bearer service compatible with many packet data networks. Chapter 6 describes a service that carries secure communications from U.S. Government digital STU-III terminals. Chapter 7 details how service is provided to analog fax machines connected to a spread spectrum system. Chapter 8 defines Radio Link Protocol Type 2 that uses the services defined in TIA/EIA-95-B to allow increased transmission speeds. Chapter 9 describes a packet data bearer service that provides higher rates (greater than the rates possible using chapter 5) by using RLP Type 2 and other services defined in TIA/EIA-95-B.

The following verbal forms are used throughout all chapters. Shall Ad 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, without 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 may 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.
