Planning Communication Networks to Deliver Educational Services.
Ballard, Richard J.; Eastwood, Lester F., Jr.
As companion to the more general document Telecommunications Media for the Delivery of Educational Programming , this report concentrates on the technical and economic factors affecting the design of only one class of educational networks, dedicated coaxial cable systems. To provide illustrations, possible single and dual dedicated cable networks are considered as ways to deliver educational services to selected institutions in the St. Louis metropolitan area. The networks described have the capacity to simultaneously distribute 35 forward and eight return channels. Cost estimates, construction techniques, and technical limitations of the systems are discussed in detail. Since user efficiency is a key factor in minimizing the cost of the system, a projection is made for the potential use of the system in the St. Louis area. Extensive appendixes concentrate on the technical functioning of the system. (EMH)
