本规范定义了使用IPCablecom功能（简称“PC/TSP”）向公众提供电信服务的电信运营商与执法机构（LEA）之间的接口，以协助LEA进行合法授权的电子监控。使用IPCablecom功能的公司在正常情况下不会是“电信运营商”相反，他们将提供信息服务。然而，一些使用IPCablecom能力的公司可能因其他行动而成为《通信协助执法法案》（CALEA）中有关使用IPCablecom能力的“电信运营商”。本规范的目的是帮助这些公司履行其在CALEA下的义务。在这方面，符合行业协会采用的公开技术要求或标准或标准的电信运营商- 设置机构应符合CALEA的协助能力要求。 如前所述，有线电视运营商通常不是电信运营商，但如果有线电视运营商已采取措施成为运营商，并使用IPCablecom提供运营商服务，则CALEA可能适用于用于实施IPCablecom的设备。出于这个原因，我们将CALEA问题作为IPCablecom规范的一部分提供考虑，以利于任何可能将此体系结构/技术作为其运营商活动一部分的人。 因此，符合本文件要求的PC/TSP、制造商或支持提供商将拥有《美国法典》第47卷第1001节等第103-414号公法第107节规定的“安全港”。 本规范定义了支持合法授权电子监控的服务和功能，以及提供截获通信和合理可用呼叫的接口- 授权时向LEA提供识别信息。

This specification defines the interface between a telecommunications carrier that provides telecommunications services to the public for hire using IPCablecom capabilities (a "PC/TSP") and a Law Enforcement Agency (LEA) to assist the LEA in conducting lawfully authorized electronic surveillance. Companies using IPCablecom capabilities will not in the normal case be "telecommunications carriers." Instead they will be providers of information services. However, some companies using IPCablecom capabilities may, by virtue of other actions, be "telecommunications carriers" for purposes of the Communications Assistance for Law Enforcement Act (CALEA) with respect to their use of IPCablecom capabilities. The purpose of this specification is to assist those companies in meeting their obligations under CALEA. In this regard, a telecommunications carrier that complies with a publicly available technical requirement or standard adopted by an industry association or standards-setting organization shall be found to be in compliance with the assistance capability requirements of CALEA. As noted, cable operators are not ordinarily telecommunications carriers, but if a cable operator has taken the steps to become a carrier, and uses IPCablecom to provide carrier services, then CALEA might apply to the equipment used to implement IPCablecom. For this reason, we are providing consideration of CALEA concerns as part of the IPCablecom specification, for the benefit of anyone who might use this architecture/technology as part of their carrier activities. Accordingly, a PC/TSP, manufacturer, or support provider that is in compliance with this document will have "safe harbor" under Section 107 of CALEA, Public Law 103-414, codified at 47 U.S.C. 1001 et seq. This specification defines services and features to support Lawfully Authorized Electronic Surveillance, and the interfaces to deliver intercepted communications and reasonably available call-identifying information to a LEA when authorized.
