12、andardThis Standard has been produced by the TR-45.6 Subcommittee of the TIA/EIA/TR-45 Committee.This document contains significant portions of material originally submitted by the Cellular Digital Packet Data Forum Inc.This document set constitutes the Cellular Digital Packet Data (CDPD) System Spe
13、cification. CDPD is a technology intended to provide packet data networking services to mobile hosts. The media used to provide these services consists of radio channels typically used for Advanced Mobile Phone System (AMPS) cellular service.Document StructureThis Standard is published as a series o

Supplementary protocol information is included fo
22、r two reasons: to help implementors better understand CDPD protocols and to support the development of test suites for the protocols. These CDPD protocol abstract test suites are described in Part 900 through Part 999.In general, there are two types of supplementary protocol information: information
23、 relative to the protocol specification and information relative to a particular implementation of the protocol.Information relative to the protocol specification can take one of two basic formats: transition state matrices and Specification and Design Language (SDL) diagrams. The selection of the b
24、est format for a given protocol depends on the characteristics of that protocol; this selection is described in Part 900.In the following Parts, the transition state matrix approach has been used to more fully define the CDPD MAC, MDLP, MNLP and MNRP protocols. In the event of any conflicteither rea
25、l or perceivedbetween this CDPD protocol supplementary information and the actual protocol definitions in Parts 402, 403, 501 and 507, the conflict shall be resolved in favor of the actual protocol definition.Information relative to a specific implementation of a protocol is described via Protocol I
26、mplementation Conformance Statements (PICSs). This information is presented via a questionnaire, known as the PICS proforma.

A description of PICS can be found in Part 900.
