... Regulation is opening major portions of the network to customer control; technologies notably fiber optics, digital switching, and software control are driving network assets into fewer, but more critical, network nodes; competition is reducing the incentives of providers to build redundancy into their networks; and customer demand is not stimulating deployment of network assets that are sufficiently robust to cover the full range of national security emergency preparedness (NSEP) contingencies.

... National Security Emergency Preparedness Resources light of society's growing reliance on information and telecomlm~nications networks and the resulting increase in risk to national security emergency preparedness, the National Security Council shoed review whether the resources available to the National Communication System are sufficient to permit it to fulfill its responsibilities for planning, implementing, and administering programs designed to decrease communications vuInerabilities for national security emergency preparedness users in an en~riro:nment of proliferating public networks. (Chapter 4)

... Recommendation No. 2: Use More Tethnology Diversity Because public network evolution is increasingly berg dri~ren by economic considerations, the Nationwide Comm~mications System shoed ask the National Security Telecommunicatione Advisory Committee to exhume how national security emergency prepared:nese needs can be met; the National Security Telecomnmnications Advisory Committee Could recommend steps to make critical network nodes more secure, reduce concentration of network traffic, and increase alternate route diversity.

... 4: Provide Priority Service As emergency services cannot be provided without preposition~ng dedicated network equipment, the National Communicatione System shot ark the Federal ComlImnication8 Colmniesion to require the ministry to deploy the network assets needed to prwide priority service for selected users during declared emergencies.

... Recommendation No. 6: Increase Radio Access Capabilities Since radio terminologies can provide a valuable source of alternative routing in emergencies, the National Communications System should consider how terrestrial and satellite radio transmission can be employed to provide route diversity for national security emergency preparedness purposes; In particular, consideration should be given as to how very small aperture terminals can be used to back up the public switched networks.

... These should include estimates of costs, time required to restore communication, the level of the restoration, telecommunications service priority adherence, and network management obstacles. Recommendation No.

... 9: Exploit Value-Added Networks Because packet switching techniques are well suited for adaptive routing, the National Com~nicatione System should devise ways to exploit the capabilities of the commercia] packet-ewitched, ~ralu~added data networks for national security emergency preparedness purposes, including message transmission, electronic mail boxes, and more robust signaling.

... 11: Retain Existing Synchronization As existing network synchronization levels already exceed those required for national security emergency preparedness, no action need be taken to increase the robustness of network synchronization beyond existing standards for norma] network operation; designers of terminal devices should engineer them to operate satisfactorily under system synchronization standards.
