DDE requires a connectivity service provided by an external company to establish the connection. It is the provider's responsibility to coordinate connectivity services. Options for connectivity can be found on the Noridian Electronic Data Interchange (EDI) website This link will take you to an external website.  under Connectivity Vendors.
