7、ll not be in any respect preclude any member or nonmember of TIA from manufacturing or selling products not conforming to such Standards and Publications, nor shall the existence of such Standards and Publications preclude their voluntary use by those other than TIA members, whether the standard is
8、to be used either domestically or internationally. TIA Documents contain information deemed to be of technical value to the industry, and are published at the request of the originating Committee without necessarily following the rigorous public review and resolution of comments which is a procedura
9、l part of the development of a American National Standard (ANS). Further details of the development process are available in the TIA Engineering Manual, located at http:/www.tiaonline.org/standards/procedures/manuals/engineering.cfm A Word from ATIS: ATIS is a technical planning and standards develo
10、pment organization that is committed to rapidly developing and promoting technical and operations standards for the communications and related information technologies industry worldwide using a pragmatic, flexible and open approach. Over 1,100 participants from more than 350 communications companie
11、s are active in ATIS 21 industry committees, and its Incubator Solutions Program. Further information on ATIS is available at http:/www.atis.org. NOTICE FROM PATENT HOLDERS The users attention is called to the possibility that compliance with this standard may require use of an invention covered by
12、patent rights. By publication of this standard, no position is taken with respect to the validity of this claim or of any patent rights in connection therewith. The patent holder has, however, filed a statement of willingness to grant a license under these rights on reasonable and nondiscriminatory

A TSP, manufactur
36、er, or support service provider that is in compliance with this Standard will have a “safe harbor” under Section 107 of the Communications Assistance for Law Enforcement Act (CALEA), Public Law 103-414: “a TSP shall be found to be in compliance with the assistance capability requirements under CALEA
37、 Section 103, and a manufacturer of telecommunication transmission or switching equipment or a provider of telecommunication support services shall be found in compliance with CALEA Section 106.”J-STD-025-A provides the enhancements necessary to support FCC 99-230, CC Docket No. 97-213, Third Report
38、 and Order and FCC 02-108, CC Docket No. 97-213, Order on Remand1. J-STD-025-B provides enhancements to further support lawfully authorized electronic surveillance of packet data telecommunication services (e.g., cdma20002packet data). 1.The FCC Third Report and Order FCC 99-230, CC Docket No. 97-21
39、3 introductory paragraph states the fol-lowing: “Specifically, we require that all capabilities of J-STD-025 (interim standard) and six of nine “punch list“ capabilities requested by the Department of Justice (DoJ)/Federal Bureau of Investigation (FBI) be implemented by wireline, cellular, and broad
40、band PCS carriers. While we are requiring that a packet-mode capability be implemented by such carriers, we are not at this time adopting technical requirements for packet-mode communications, but will permit packet-mode data to be delivered to law enforcement under the interim standard, discussed b
41、elow, pending further study of packet-mode communications by the telecommunications industry.”2. cdma2000 is a registered trademark of the Telecommunications Industry Association (TIA-USA).ANSI/J-STD-025-B Document Revision History123456789101112131415161718192021222324252627282930313233343536373839
