4.2.3 Virtual Networking (Virtual Network)
With this type of networking all the PINXs are connected to the public ISDN net-
work. The connections between the PINX are switched lines, not direct physical
connections. The characteristics of this type of networking are:
• Line resources are required for the current connections only.
• Voice and data traffic via the public network is charged according to duration
and distance.
• The necessary networking-specific equipment is minimal.
• The range of services available in a virtual network depends on the range of
services offered by the network provider.

Fig. 1.19: Example of a virtual network
In this example (Fig. 1.19) all three PINXs are virtually interconnected via the public
virtual network. This depends on the configuration. If for example there is no
need for a virtual connection between PINX 1 and PINX 3, the configuration can
be implemented accordingly.
