NCS Priority and Other Services

The NCS offers a wide range of National Security and Emergency Preparedness (NS/EP) communications services that support qualifying Federal, State, local and tribal government, industry, and non-profit organization personnel in performing their NS/EP missions. (Priority Telecommunications Services Brochure)

NS/EP Priority Telecommunications

Government Emergency Telecommunications Service (GETS) - provides emergency access and priority processing in the local and long distance segments of the public switched wireline network. Used in an emergency or crisis situation during which the probability of completing a call over normal or other alternate telecommunication means has significantly decreased. (GETS Brochure)

Telecommunications Service Priority (TSP) - provides service vendors with a Federal Communications Commission (FCC) mandate for prioritizing service requests by identifying those services critical to NS/EP. A telecommunications service with a TSP assignment is assured of receiving full attention by the service vendor before a non-TSP service. (TSP Brochure)

Wireless Priority Service (WPS) - provides priority cellular network access. The WPS was approved by the FCC for NS/EP requirements on a call-by-call priority basis. The NCS executes the program on behalf of the Executive Office of the President. Only individuals in NS/EP key leadership positions are authorized use of WPS (WPS Brochure).

Modeling and Analysis

Network Design and Analysis Capability - provides NCS member agencies and other government organizations with analyses of the communications infrastructure. The NDAC supports modeling and analysis of the public switched network (PSN) including the public switched telephone network (PSTN), Internet Protocol (IP) networks, internet telephony, next generation packet switched networks, control systems, and cable, wireless, and satellite networks. The NDAC also enables studies of natural and man-made disruptions to the PSN, and provides the ability to conduct vendor independent analyses, create models and methodologies to identify vulnerabilities and congestion, and identify network effectiveness solutions. Specifically, the NDAC:

  • Supports planning and provisioning of NS/EP communications under all circumstances, including crisis or emergency, attack, recovery, reconstitution
  • Maintains current/valid representation of PSN
  • Enables custom modeling/simulation studies of communications networks under a variety of NS/EP conditions
  • Performs analyses of PSN dependability and resiliency under stresses induced during NS/EP situations
  • Examines effect of new and emerging technologies on the PSN and the Internet infrastructure, specifically how these effects may modify future NS/EP requirements
  • Incorporates flexibility to customize network architectures and routing schemes, emulate effects of emerging technologies, and introduce new carrier network data

Access to these services may be obtained by contacting the NDAC Program Manager at at (703) 235-5838.

Route Diversity Project - provides technical and regulatory information and assistance to help increase the resiliency of communications networks. Technical information includes the Route Diversity Methodology (RDM), Abridged Route Diversity Methodology (ARDM), and technology evaluation results. If requested and if funding permits, NCS will assist agencies in determining the physical mapping of their local access (outside plant) and will provide recommendations for achieving optimum diversity .

National Coordinating Center (NCC) for Telecommunications

Shared Resources High Frequency Radio Program (SHARES) - The SHARES HF Radio Program brings together the assets of over 1,000 HF radio stations worldwide to voluntarily pass emergency messages when normal communications are destroyed or unavailable. SHARES uses common radio operating and message formatting procedures and more than 250 designated frequencies. Participation in SHARES is open to all Federal departments and agencies and their designated affiliates on a voluntary basis. More than 90 Federal, state, and industry organizations currently contribute resources throughout the United States and in 26 countries and U.S. possessions

Telecom ISAC - In January 2000, the National Coordinator for Security, Infrastructure Protection, and Counterterrorism designated the NCC-ISAC as the ISAC for telecommunications. On March 1, 2000, the NCC-ISAC commenced operations. The initial NCC-ISAC membership is based on NCC membership, which is evolving to reflect a broader base of technologies comprising the telecommunications infrastructure. NCC-ISAC will support the mission assigned by Executive Order 12472 and the national critical infrastructure protection goals of government and industry. The NCC-ISAC will facilitate voluntary collaboration and information sharing among its participants gathering information on vulnerabilities, threats, intrusions, and anomalies from telecommunications industry, government, and other sources. The NCC-ISAC will analyze the data with the goal of averting or mitigating impact upon the telecommunications infrastructure. Additionally, data will be used to establish baseline statistics and patterns and maintained to provide a library of historical data. Results will be sanitized and disseminated in accordance with sharing agreements established for that purpose by the NCC-ISAC participants.


Emergency Response Training and Exercise Support

Our mission is to ensure NCS readiness, enhance partnerships within government and industry, coordinate telecommunications operational training among our Emergency Support Function (ESF) #2 Support Agencies as defined in the National Response Framework (NRF), and to provide skilled civilians and reservists during crises and emergencies.

NCS Augmentee Program - The National Communications System (NCS) Augmentee Program was established in 1988 to provide a cadre of military reservists to enhance the capabilities of the Office of the Manager, NCS (OMNCS); the National Coordinating Center for Telecommunications (NCC); and NCS Regional Managers (RMs) during national crises and emergencies. The NCS Augmentee Program consists of the U.S. Army reservists participating in the Individual Mobilization Augmentee (IMA) Program
