3、purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular need. Existence of such Standards and Publications shall not in any respect preclude any member or nonmember of WEI
4、A from manufacturing or selling products not conforming to such Standarcis and Publications, nor shall the existence of such Standards and Publications preclude their voluntary use by those other than TIA/IEIA members, whether the stanard is to be used either domestically or internationally. Standar
5、ds, Publications and Bulletins are adopted by WEA in accordance with the American National Standards Institute (ANSI) patent policy. By such action, TIA/EZA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Standard, Publication or
6、Bulletin. Technical Bulietins are distinguished from TIA/EIA Standards or Interim Standards, in that they contain a compilation of engineering data or information useful to the technical community, and represent approaches to good engineeIing practices that are suggested by the formulating committee
7、. This Bulletin is not intended to preclude or discourage other approaches that similarly represent good engineering practice, or that may be acceptable to, or have been accepted by, appropriate bodies. Parties who wish to bring other approaches to the attention of the formulating committee to be co
8、nsidered for inclusion in future revisions of this Builetin are encouraged to do so. It is the intention of the formulating committee to revise and update this Bulletin from time to time as may be occasioned by changes in technology, industry practice, or government regulations, or for other appropr

This document has been submitted to APCO/NASTD/FED by the Telecommunications Industry Association (TIA), as provided
12、 for in a Memorandum of Understanding (MOU) dated December 1993. That MOU provides that APCO/NASTD/FED will devise a Common System Standard for digital public safety communications (the Standard), and that TIA shall provide technical assistance in the development of documentation for the Standard. T
13、his document has been developed with inputs from the APCOTTIA Project 25 Interface Committee (APIC), the APIC Trunking Task Group, and TIA Industry members. This document is being published because it is felt that there is an urgent need for technical information on the emerging digital techniques f
14、or Land Mobile Radio Service. This document describes the control procedures for trunked systems meeting the Project 25 requirements. These definitions are necessary to insure interoperability of trunked radio units. As other documents describing the trunking protocol are developed, this document wi
15、ll be subject to change, Additional reason codes and additional messages covering working channel maintenance may be needed. Some efforts have been made to ensure accuracy, but it should be understood that conformance tests remain to be developed and proven. This Bulletin is not a TIA standard. It p
16、resents trunking operation which was recommended by TIA to APCO/NASTD/FED as being suitable for use as part of their standard for a digital public safety radio system (Project 25). TIA expects that APCO/NASTD/FED will establish and publish one or more standards for trunking operation. Rich Comroe Co
