2、ting interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for their particular need. The existence of such Standards and Publications shall not in any respect preclude any member or non-member of TIA from manufac

3、turing or selling products not conforming to such Standards and Publications. Neither shall the existence of such Standards and Publications preclude their voluntary use by Non-TIA members, either domestically or internationally.

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 1992 and am

20、ended 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 provide technica

21、l 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 Standard. The a

22、ppearance 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” implementations exclusiv

23、ely. This document provides a specification of the Packet Data Host Network 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 Group (D

24、TG). The 1stedition (Original) of this document provides a standalone document for the Packet Data Host Network Interface based on material originally published in TIA-102.BAEB-A. This document cancels and replaces the material specific to the Packet Data Host Network Interface in TIA-102.BAEB-A. Th

25、e TIA makes no claims as to the applicability of the information contained in this document for any purpose although it is believed that the information will prove to be invaluable to manufacturers and operators of equipment based on the TIA-102 series of documents. Some aspects of the specification

26、s 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 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

27、-Safety Communications Officials (APCO), the National Association of State Telecommunications Directors (NASTD), and the various agencies of the Federal government (FED). TIA-102.BAEF ii Patent Identification The readers attention is called to the possibility that compliance with this document may r

28、equire the use of one or more inventions covered by patent rights. By publication of this document, no position is taken with respect to the validity of those claims or any patent rights in connection therewith. The patent holders so far identified have, we believe, filed statements of willingness t

29、o grant licenses under those rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to obtain such licenses. The following patent holders and patents have been identified in accordance with the TIA intellectual property rights policy: No patents have been identified T

30、IA shall not be responsible for identifying patents for which licenses may be required by this document or for conducting inquiries into the legal validity or scope of those patents that are brought to its attention.
