MULTIPURPOSE COMMUNICATIONS SYSTEM MODELS WERE DEVELOPED FOR APPLICATION TO HIGHER EDUCATION. THREE MODEL SYSTEMS - INTRASTATE, INTERSTATE, AND EDUCATIONAL RESOURCES - WERE DESIGNED. THESE SYSTEM DESIGNS WERE ESTABLISHED FOR EASY EVALUATION AND MAXIMUM FLEXIBILITY, WITH A MINIMUM OF PRESET AUTOMATIC EQUIPMENT. TWO ALTERNATIVE TRANSMISSION SYSTEMS WERE PRESENTED--(1) ONE BASED ON THE TELPAK TARIFF OF TELEPHONE COMPANIES, PROVIDING A NARROW-BAND SERVICE, AND (2) ONE BASED ON MULTIPURPOSE BROADBAND MICROWAVE TRANSMISSION. PLANS FOR EXPERIMENTAL OPERATION AND EVALUATION OF THE THREE MODELS IN A FOLLOWUP PHASE WERE INDICATED. RELATED INFORMATION MAY BE FOUND IN ED 003 165. (RS)
