Customer network reconfiguration applications utilizing digital cross-connect systems

Abstract: The author discusses four customer applications based on digital-cross-connect (DCS) systems. The applications which entail customer control of DCS, are: citywide Centrex with adaptive differential pulse-code modulation, disaster recovery, and network optimization, the use of compressed voice and compressed video networks, and cellular radio. >

Computer backup pools, disaster recovery, and default risk

Abstract: There is a growing popularity of computer backup pools, where a few members share the ownership, or right for service, of a computer center. Such a center stands by to provide for the lost computing capacity of a member suffering a computer breakdown and disaster recovery. The efficiency of such a solution may be examined from various points of view, such as costs, response time, reliability etc. We focus on the reliability of such an arrangement. Two types of default risks are discussed: the probability that the center itself will break down when needed, so that it would be unable to provide service (this is similar to the traditional measure of a "probability of ruin") and a "perceived probability of ruin" (the probability that a member will be affected by the failure of the center). We borrow the concepts of probability of ruin from the risk management and insurance literature, in order to reach explicit relationships between these probabilities and the pricing of a mutual computer pool. It is shown that the membership fee for each participant must be a function of both the payments of all members and their loss (call for service) distributions, reflecting thereby the simultaneity of and mutual interdependence of members.

Characteristics of Citizen Groups Which Emerge With Respect to Hazardous Waste Sites

Abstract: An increasingly noticeable feature of American society is the presence of newly formed groups of private citizens concerned with preventing and preparing for possible disasters or with recovering from actual impacts of such types of community crises. Their increased visibility and activity is probably reflective of broader trends in the country on the rights of consumers, and emphasis on participatory democracy, and an interest in organized self help, that are some of the legacies of the social turmoil of the late 60’s and early 70’s (for a partial examination of the historical background, see Boyte, 1980). Apart from any changes in popular beliefs and values about the rights and obligations of individual citizens to work together, there has also been an increase in local community and formal advocacy groups interested in activating and mobilizing private citizens (examples of the variety of such groupings are presented in Freeman, 1983). Thus, it is not surprising that there are also a variety of public interest groups across the nation who are consciously undertaking deliberate efforts to educate and train people in disaster preparedness, response, recovery and mitigation. The larger changes in American society suggest that it should be anticipated that not only will emergent groups of citizens continue to surface in potential and actual disaster situations, but that their numbers are very likely to increase in the future.

Planning and Implementing a Disaster Recovery Capability for a Mainframe-Based Hospital Information System: Duke University Medical Center's Experience

Abstract: Since October 1986, the Medical Center Information Systems Department at Duke University Medical Center (DUMC) has been developing and implementing a plan to provide for the continuation of the functions performed by Duke Hospital's central computing system in the event of a disaster that would disable the central hardware configuration for an extended amount of time. The key characteristic of the plan is that it provides for the full function and performance of the system to be returned to the end users within twenty four hours of the primary system's failure.
