Overview of Lawfully Authorized Electronic Surveillance Standards in Telecommunications

This document provides an overview of the Lawfully Authorized Electronic Surveillance (LAES) efforts facilitated by ATIS’ Packet Technologies and Systems Committee (PTSC) and its collaboration with various organizations, including TIA and WTSC. Key historical milestones include the development of American National Standards (ANS) J-STD-025 and its subsequent revisions, ensuring compliance with the U.S. Communications Assistance for Law Enforcement Act (CALEA). Highlights include significant advancements in voice over packet technologies, call control protocols, and ongoing initiatives to standardize electronic surveillance practices across telecommunications networks.

  2. ATIS’ Packet Technologies and Systems Committee (PTSC) • Work in ATIS Packet Technologies and Systems Committee (PTSC) Lawfully Authorized Electronic Surveillance (LAES) Subcommittee • Stimulated by passage of the U.S. Communications Assistance for Law Enforcement Act (CALEA) in 1994 • Working with ATIS Wireless Technologies and Systems Committee (WTSC) and TIA on U.S. Solutions GSC: Standardization Advancing Global Communications

  3. ATIS’ Packet Technologies and Systems Committee (PTSC) • Created Joint common specifications with TIA and others intended to serve as “safe harbor” • American National Standard (ANS) J-STD-025 in 1997 … circuit-switched PSTN • ANS J-STD-025-A in 2003 … plus “punch list items” • ANS J-STD-025-B (under development) … packet-switched GSC: Standardization Advancing Global Communications

  4. ATIS’ Packet Technologies and Systems Committee (PTSC) • American National Standards (ANS) T1.678 – LAES for Voice over Packet Technologies in Wireline Telecommunications Networks • Included by reference in pending ANS J-STD-025-B • Focus on basic call control for Voice Services over IP • ASN.1 modules may be imported by other standards • ANS T1.678 (version 2) Approved • Focus on multi-party call control • (transfer, conferencing, …) • Continues to support message headers compatible with ANS J-STD-025, or – alternately – with ANS SCTE 24-13 2001 GSC: Standardization Advancing Global Communications

  5. ATIS’ Packet Technologies and Systems Committee (PTSC) PTSC LAES Current Work Summary • VoP Advanced Conferencing • Initial draft created • IP Network Access (T1.IPNA) • Clarifications of Model and of Packet Data Summary Reports • Technical Report on NGN • Updated view of architecture for consistency with PTSC Signalling, Architecture, and Control (SAC) Subcommittee • Technical Report on Telecommunications Service Provider (TSP) Job Aid • Clarification of roles in LI reporting GSC: Standardization Advancing Global Communications
