Implementation of the Communications Assistance for Law Enforcement Act

This document examines the definition of ``telecommunications carrier'' set forth in section 102 of the Communications Assistance to Law Enforcement Act (CALEA), which determines which entities and services are subject to the assistance capability and other requirements of CALEA, and discusses how the definition applies to various types of service providers. It also provides guidance regarding the factors the Commission will consider in making determinations under section 109 of CALEA as to whether compliance with CALEA's assistance capability requirements is ``reasonably achievable'' for particular carriers, and the showings to be made by entities filing petitions under section 109.
