In the example, let the public network supports only 32 bytes of user information. The application requires 13 bytes of ASAI user information (15 bytes of user data), UCID (10 bytes of user data), and 8 collected digits (7 bytes of user data - 4 plus 1 plus 2 for the header). The application does not require Other LAI Information. Also, call time at the sending Communication Manager is brief because calls are not queued before interflow takes place and tracking as a single call is not required.

By dedicating appropriately named VDNs at the receiving Communication Manager, the public network can support the application. Because the needed data items require the entire 32 bytes of user data, the priority fields for the In-VDN Time, VDN Name, and Other LAI Information must be set to blank.
