Technology Plan(What we promised)
Revolutionize cost structure• Per-minute to capital investment• Gateways to legacy systems
Enable new applications• Or at least old applications that were
not cost effective
Mid-Level Technology Applications
Interviews Guest lecturers Remote seminars Contract negotiation Conference room overflow Avoid travel Facilitate research partnerships
Mid-Level ProjectConference Room System

Early AdoptersSchool of Education
Collaborative classroom project Few to few model (seminar) Faculty-student groups in both
locations Video, audio, whiteboards, etc Partners:
• Iowa State• Florida State
Early AdoptersSchool of Education
Bermuda• Curriculum Development• Teacher Education• Videoconferencing back to
Charlottesville• Link Bermuda classrooms to the world
Early AdoptersTelemedicine
ISDN-based services to prisons Telemedicine Workstation
• Rural Western Virginia Healthcare• Audio, video via VCON H.323• Stethoscope• Records, file transfer
Affordable via Network Virginia
Distance Education(One to many model)
Traditionally at UVa• Division of Continuing Education• Satellite, ISDN, now also ATM
But - we limit ATM to users• Council for Information Management
(CIM)• Clinch Valley College
University Level Issues
University Mission and Distance Education
Division of Continuing Education• Full cost recovery operation• Some departments view as a tax
Centralized vs distributed
Technology Vision(What we delivered)
Guest lecturers Remote seminars Distance education Conference room overflow Facilitate research partnerships Avoid travel
• ITC conference rooms
Feedback:More central support
Turn-key setup service Better documentation ISDN Gateway & Billing
Good to be the phone company
Future successes
Interviews & contracts On campus meeting avoidance Lots of investment by departments Large numbers of courses Significant use by researchers Building slowly - need more early
adopters
