ISDN access to fast packet data network
First Claim
1. A data communications network for providing user terminals with access to a remote data center comprising:
- a first local area network (LAN) arranged at said data center,a fast packet network coupled to said first LAN for providing interconnection between said data center and a first central office having a fast packet interface coupled to said fast packet network,an ISDN switch coupled to said user terminals via ISDN lines to provide said user terminals with Centrex services, anda second LAN provided at said first central office for interfacing said fast packet network with said ISDN switch, and having a bus topology including a plurality of devices coupled to a common bus,wherein said fast packet interface comprises a plurality of fast packet bridges coupled to said common bus, andsaid second LAN is arranged so as to interconnect devices for bridging said second LAN to said ISDN switch, and devices for bridging said second LAN to said fast packet network.

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.
