4.3 Choosing the Appropriate Networking Type
The choice of the appropriate topology depends on the following factors, among
others:
• Number of locations
• Distance between the locations
• Calling rate between the locations
• Networking equipment required
• Existing data network (see System Manual AIP 6400
• Scope of performance required
With virtual networking, the costs incurred consist of the basic charge for connec-
tions and DDI numbers and the charges per call, while a dedicated line incurs only
fixed costs (for the rental of the leased line for example). The following compari-
son (Fig. 1.22) shows that virtual networking is better suited to systems with lower
calling rates while networking with leased lines can be more advantageous for
