Abstract
Abstract A Health Care Information Network is provided that allows subscribers access to a data center. A LAN arranged at the data center is connected through a frame relay network to a LAN of a similar type located at a central office. ISDN/LAN bridges link the LAN to an ISDN switch that provides the subscribers with ISDN Centrex services. A PC at the subscriber's site can gain the subscriber access to the ISDN switch via an ISDN Centrex line. The subscribers are provided with voice, image and data transmission, and can communicate not only with the data center but with each other. For disaster recovery, e.g., if a connection is broken or defective, the network can provide alternative routes. A network manager at the data center is able to configure the network, monitor its status and react to failures and overloads on a real time basis.
