47 C.F.R. § 202.2
NS/EP planning in government and industry with respect to effective conservation and use of surviving telecommunications resources in a disaster, emergency or postattack period must provide for orderly and uninhibited restoration of services by the carriers and authoritative control of services allocation which will assure that priority will be afforded the most critical needs of government and the private sector with respect to these objectives.
(a) The preservation of the integrity of characteristics and capabilities of the Nation's telecommunications systems and networks during wartime or non-wartime emergencies is of the utmost importance. This can best be accomplished by centralized policy development, planning, and broad direction. Detailed operations management will remain decentralized in order to retain flexibility in the use of individual systems in responding to the needs of national security, survival and recovery. Each Federal agency responsible for telecommunications systems operations, and the carriers, are responsible for planning with respect to emergency operations. Guidance in this matter has been issued from a number of sources and contained in:
(3) The National Communications System Management Plan for Annex
C-XI (Telecommunications) Federal Emergency Plan D (Classified).
