| VA | Improve Telecommunications Infrastructure and Internet Connectivity | Budget Code: | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
This program activity is to test expanded telecommunications configurations that will connect the clinicians desktop to Internet resources. Components to be tested include workstations at desktop, Local Area Network (LAN) connections, high speed facility communications backbones, routers connecting to the VA's Wide Area Network and interconnections with the Internet.
All VA facilities are currently connected to each other by an electronic packet switched wide area network (WAN). The network is used to exchange medical (text and image), administrative, central reporting, and electronic commerce data across the VA and through gateways to facilities outside the VA. Traffic has grown three fold between 1990 and 1993. This network currently transports 75 billion characters per month. Basic nationwide Internet connectivity infrastructure is installed. An Internet gateway links the VA electronic mail systems to Internet and provides basic connectivity to VAMCs nationwide. All Medical center computer users are able to send and receive Internet mail. The testing will investigate the feasibility of furnishing nationwide network connection to Internet. The goal will be to provide expanded functionality, improved access and upgraded performance with appropriate security. |
