4.2.2 Leased-line Networking (Leased-line Network)
With this type of networking, the PINXs are connected with specific or leased ded-
icated lines. The characteristics of this type of networking are:
• fixed line resources
•fixed costs
[1] Connection to the public network
[2] Physical connection between two PINXs

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.
