The Development of the Educational Telephone Network (ETN) and the Subsidiary Communications Authorization (SCA) Systems.
Parker, Lorne A.
In the last four years, University Extension, the University of Wisconsin, has developed two new communications, the Educational Telephone Network (ETN) and Subsidiary Communications Authorization (SCA). ETN is an interacting, party-line type connection which links instructors with remote classrooms in courthouses, hospitals, and universities. SCA is an electronic technique which allows a second signal to be broadcast on an FM channel and received only by individuals with the appropriate multiplexing receiving equipment. Both systems have been used to deliver educational programing with a typical format consisting of lecture sessions followed by question and answer sessions. Each can be used to provide broad dissemination of community service messages. (EMH)
