1990 Establishment of VERNET –Colleges and universities – public and private –Research sites –Limited participation by Virginia Community College System –Strict acceptable use policy Plans begin for Blacksburg Electronic Village Disconnected from State Government Services

1992 VERNET users expanding –Community colleges –K-12 schools –Private labs, e.g., Newport News Shipbuilding, Reynolds Metals Blacksburg Electronic Village –Partnership with community, Bell Atlantic –Citizen access to Internet

1992 Data Private Line Networks for State Agencies Voice on Centrex or Analog PBX Long Distance Statewide Virtual Private Network (VPN) Established Very little wireless or mobile telephone One-way video via satellite

Private Line Network Redundant private lines Hotsite switching 400 lines or 900 locations LATA 236 LATA 246 LATA 929LATA 928 LATA 252 LATA 248LATA 250 LATA 956LATA 244 LATA927 CommonwealthTelecommunications Network (CTN) 1992

Virginia Adopts Statewide Strategic Plan –Merger of voice, data and video services –ATM infrastructure to be built and owned by the private sector Virginia Community College System contracts with Virginia Tech to plan major network upgrade –Statewide coverage – 39 sites –Equality of access
