President's National Security Telecommunications Advisory Committee (NSTAC): Information Technology Progress Impact Task Force Report on Convergence [May 2000] [open pdf - 131KB]
"This report identifies implications of Convergence (as defined in Section 1.3) for existing NS/EP priority services, and examines evolving network technologies and capabilities that could assist in satisfying existing NS/EP functional requirements in an NGN environment. Further, The national security and emergency preparedness (NS/EP) community depends heavily on priority treatment of voice calls within the public switched network (PSN) to support NS/EP operations. This priority treatment is provided under the Telecommunications Service Priority (TSP) program, a circuit restoration and provisioning service, and the Government Emergency Telecommunications Service (GETS) program, a high probability of call completion service. Telecommunications service providers are rapidly implementing packet-based data networks and plan to transition traffic onto the Next Generation Network (NGN). As a result, the National Security Telecommunications Advisory Committee's (NSTAC) Industry Executive Subcommittee (IES) established the Information Technology Progress Impact Task Force (ITPITF) to examine the implications of the evolving public network architecture for priority treatment of NS/EP voice and data traffic. Specifically, the IES directed the ITPITF to examine the potential impact of Internet Protocol (IP) network-PSN convergence on PSN-specific NS/EP priority services."
