NS/EP Telecommunication Services Functional Recommendations
Description
Voice Band ServiceThe service must provide voice band service in support of presidential and other communications.
InteroperabilityServices 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 CoverageServices must be readily accessible to support the national security leadership and inter- and intra-agency emergency operations, wherever they are located.
Enhanced Priority TreatmentServices supporting NS/EP missions must be provided priority treatment over other traffic.
AnonymitySelected 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).

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.
RestorabilityShould 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 ServiceThe service must provide broadband service in support of NS/EP missions (e.g., video, imaging, web access, multimedia).
Scaleable BandwidthNS/EP users must be able to manage the capacity of the communications services to support variable bandwidth requirements.
AffordabilityServices must leverage network capabilities to minimize cost (e.g., use of existing infrastructure, commercial off-the-shelf technologies, services).
Reliability/AvailabilityServices must perform consistently and precisely according to their design requirements and specifications, and must be usable with high confidence.

SummarySummarySummarySummary
NCS has worked with industry (vendors & service providers) to define the priority capability requirements
NCS and industry both are working with Standards Bodies to incorporate NS/EP priority capabilities into standards
NCS has participated in industry-sponsored interoperability test events and prototyping of priority requirements
NCS has funded some vendors and carriers for development of initial NGN priority capabilities
