22、D(This foreword in not part of this bulletin.) This document has been published by the Telecommunications Industry Association (TIA) in accordance with the terms and conditions provided for in a Memorandum of Understanding (MoU) executed by and between the TIA, the Associated Public-Safety Communica
23、tions Officials (APCO), the National Association of State Telecommunications Directors (NASTD), and the various agencies of the Federal government (FED). This document was originally developed by the TIA TR-8.5 Signaling and Data Transmission subcommittee, and TIA Industry members. Members of the TI
24、A TR-8.5 Signaling and Data Transmission Subcommittee progressed the original document through the TIA standards development process to its status as a Project 25 standard. This document defines the TCP/UDP port numbers for use with P25 standard applications. The TIA makes no claims as to the applic
25、ability of the information contained in this document for any purpose although it is believed that the information will prove to be invaluable to designers of Project 25 compliant equipment. Some aspects of the specifications contained in this document may not have been fully operationally tested; h
26、owever, 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. TIA-102.BAJD ii Patent Identification The readers attention is called to the possibility that compliance with this document may require the
27、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 to grant lice
28、nses 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.TIA shall not
29、 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.

33、 in IETF RFCs that are intended for use with the IP protocol. Both protocols use port numbers whose values are governed by the IANA 3. The IANA has set aside a range of “dynamic/private“ port numbers that are usable without assignment by the IANA 1.2.2.It is necessary to reserve a range of these dyn
34、amic/private port numbers for P25 applications, so that manufacturers can develop interoperable P25 applications, and also develop applications outside the scope of P25 that do not conflict with P25 applications in their use of TCP/UDP port numbers. Port numbers in this reserved range are assigned t
35、o standard P25 applications for use as default port number values. 1.1 Scope This document assigns TCP/UDP port numbers to P25 applications, and reserves a range of the IANA dynamic/private port numbers for assignment to future P25 applications.1.2 References 1.2.1 Informative References 1 RFC 768:

40、ociation TCP. Transmission Control Protocol UDP. User Datagram Protocol 2 TCP/UDP Port Number Assignment A port number is a 16 bit value that identifies the source or destination of TCP or UDP packets. In a TCP or UDP packet, the port number is used in the source or destination port number field in
41、accordance with the TCP 2 or UDP 1 protocols. Manufacturers of equipment to be deployed in accordance with P25 specifications have the option of using TCP/UDP port numbers for non-P25 applications. To avoid conflicts with P25-assigned port numbers, it is necessary to identify a range of port number
42、values reserved for P25-assigned port numbers from the IANA “dynamic/private“ port number range (see 1.2.2), so that manufacturers do not use numbers in this range for other purposes. Manufacturers should not use port numbers reserved for P25 applications as the default port number for non-P25 appli
43、cations. Manufacturers may use port numbers not reserved for P25 applications for non-P25 applications. In addition, P25-assigned port numbers are used within the P25 technical specifications as default values for P25 standard applications that use TCP and UDP protocols.TIA-102.BAJD3 Port numbers as
44、signed to P25 applications shall be used as the default destination port number for those applications. Port numbers assigned to P25 applications should be configurable to deal with network-specific conflicts and security issues.The port numbers are assigned as shown in Table 1: Table 1 - Port Numbe
