Abstract
An intelligent network implementing processes and apparatus for supporting ATM/Vnet services. The intelligent network comprises the ability to receive an ATM VNET call at an ATM switch associated with a service node of the intelligent network, translate the dialed VNET number and then extend the call to a correct termination. Prior to the outdial, source address and subscription validation, destination address screening, source address screening and VNET number translation are performed. In one embodiment, assuming that the VNET call is an ATM to ATM call, no number translation is required. In placing Vnet/ATM calls, the network does all resource allocation, e.g., bandwidth reservation and allocation. The resource specification in the ATM setup message (e.g., bandwidth) is validated against the customer's subscription versus the current network utilization.
