Integrated ISDN D-server for intelligent networking

It is shown how a D-server used in the private networking environment can be used to increase the value of a private network by routing excess traffic (incremental peak traffic) via the public ISDN (integrated service digital network) and paying only for the time used. It is shown how a D-server can be used to increase the availability of the private network through bandwidth restoral and how a D-server provides the feature enhancements to non-ISDN PBXs by acting as the surrogate for the PBX in the ISDN environment. Thus, an integrated ISDN D-server can be used on an intelligent node multiplexer in a private T1 network to form a hybrid network, providing enhanced connection, capabilities for increased reliability, accessing ISDN services, and reducing costs.<>
