This document has been created in response to a request by the APCO/NASTD/FED1Project 25 Steering Committee as provided for in a Memorandum of Understanding (MOU) dated April
23、1992 and amended December 1993. The MOU states APCO/NASTD/FED shall devise a Common System Standard for digital public safety communications (the Standard) commonly referred to as Project 25 or P25, and that TIA, as agreed to by the membership of the appropriate TIA Engineering Committee, will provi
24、de technical assistance in the development of documentation for the Standard. If the abbreviation “P25” or the wording “Project 25” appears on the cover sheet of this document when published that indicates the APCO/NASTD/FED Project 25 Steering Committee has adopted this document as part of the Stan
25、dard. The appearance of the abbreviation “P25” or the wording “Project 25” on the cover sheet of this document or in the title of any document referenced herein should not be interpreted as limiting the applicability of the information contained in any document to “P25” or “Project 25” implementatio
26、ns exclusively. This document provides a specification of the Mobile Data Peripheral Interface for TIA-102 Packet Data. This document was developed by the TIA TR-8.5 Signaling and Data Transmission Subcommittee based on materials originated by the APCO Project 25 Interface Committee (APIC) Data Task
27、 Group (DTG). The 1stedition (Original) of this document provides a standalone document for the Mobile Data Peripheral Interface based on material originally published in TIA-102.BAEA-A and TIA-102.BAEB-A. This document cancels and replaces the material specific to the Mobile Data Peripheral Interfa
28、ce in TIA-102.BAEA-A and TIA-102.BAEB-A. There is one annex in this document. Annex A is informative and is not considered part of this specification. The TIA makes no claims as to the applicability of the information contained in this document for any purpose although it is believed that the inform
29、ation will prove to be invaluable to manufacturers and operators of equipment based on the TIA-102 series of documents. Some aspects of the specifications contained in this document may not have been fully operationally tested; however, a great deal of time and good faith effort has been invested in
30、 the preparation of this document to ensure the accuracy of the information it contains. 1APCO/NASTD/FED is an abbreviation for the Association of Public-Safety Communications Officials (APCO), the National Association of State Telecommunications Directors (NASTD), and the various agencies of the Fe
31、deral government (FED). TIA-102.BAEG ii Patent Identification The readers attention is called to the possibility that compliance with this document may require the use of one or more inventions covered by patent rights. By publication of this document, no position is taken with respect to the validi
32、ty of those claims or any patent rights in connection therewith. The patent holders so far identified have, we believe, filed statements of willingness to grant licenses under those rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to obtain such licenses. The fo
33、llowing patent holders and patents have been identified in accordance with the TIA intellectual property rights policy: No patents have been identified TIA shall not be responsible for identifying patents for which licenses may be required by this document or for conducting inquiries into the legal
34、validity or scope of those patents that are brought to its attention. TIA-102.BAEG iii Table of Contents 1.

Introduction The objective of this document is to provide a specification of the Mobile Data Peripheral Interface which is designated as the A Interface in 8. The term “A Interface” is used throug
42、hout the remainder of this document as a short form of “Mobile Data Peripheral Interface” and has equivalent meaning. 1.1 Scope This document specifies the protocols utilized on the A Interface. The information necessary to enable interoperable services and functionality on this interface is provide
43、d in this document or referenced in other documents as appropriate. This document assumes the reader has a good working knowledge of the Data Overview and Specification 8. 1.2 References The appearance of “Project 25” in references below indicates the TIA document has been adopted by the APCO/NASTD/
44、FED Project 25 Steering Committee as part of its Project 25 standard, i.e. “the Standard.” 1.2.1 Normative References The following documents contain provisions that, through reference in this text, constitute provisions of this document.
