6. 6 White House CWG Report July 2001 NS/EP Telecommunication Services Functional Recommendations Description Voice Band Service The service must provide voice band service in support of presidential and other communications. Interoperability Services must interconnect and interoperate with other selected government or private facilities, systems, and networks. Survivability/Endurability Services must be robust to support surviving users under a broad range of circumstances, from the widespread damage of a natural or man-made disaster up to and including nuclear war. International Connectivity Services must provide access to and egress from international carriers. Ubiquitous Coverage Services must be readily accessible to support the national security leadership and inter- and intra-agency emergency operations, wherever they are located. Enhanced Priority Treatment Services supporting NS/EP missions must be provided priority treatment over other traffic. Anonymity Selected users must be able to use NS/EP services without risk of usage being traced (i.e., without risk of user or location being identified).

7. 7 White House CWG Report July 2001 NS/EP Telecommunication Services Functional Recommendations Description Secure Networks Networks must have protection against corruption of, or unauthorized access to, traffic and control, including expanded encryption techniques and user authentication, as appropriate. Restorability Should a disruption occur, services must be capable of being reprovisioned, repaired, or restored to required service levels on a priority basis. Mobility The communications infrastructure must support transportable, redeployable, or fully mobile communications (e.g., personal communications service, cellular, satellite, high frequency radio). Broadband Service The service must provide broadband service in support of NS/EP missions (e.g., video, imaging, web access, multimedia). Scaleable Bandwidth NS/EP users must be able to manage the capacity of the communications services to support variable bandwidth requirements. Affordability Services must leverage network capabilities to minimize cost (e.g., use of existing infrastructure, commercial off-the-shelf technologies, services). Reliability/Availability Services must perform consistently and precisely according to their design requirements and specifications, and must be usable with high confidence.
