37、to assist the LEA in conducting lawfully authorized electronic surveillance. A TSP, manufacturer, 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
38、TSP shall be found to be in compliance with the assistance capability requirements under CALEA 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
39、 provides the enhancements necessary to support FCC 99-230, CC Docket No. 97-213, Third Report 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
40、(e.g., cdma20002packet data). 1.The FCC Third Report and Order FCC 99-230, CC Docket No. 97-213 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 Justi
41、ce (DoJ)/Federal Bureau of Investigation (FBI) be implemented by wireline, cellular, and broadband 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 perm
42、it packet-mode data to be delivered to law enforcement under the interim standard, discussed below, 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
