You can identify the plan for each application by the application number and a name. The plan specifies the remote servers to be polled by the application and identifies each with a number called the Location Number. The plan also specifies the numbers for the status poll and interflow VDNs for each remote server. Whatever you dial to reach the VDNs is what you must enter in the fields: full length numbers as well as AAR, ARS, UDP, or public network numbers work.
