A "Pavilion Version" of the OTN will also be available at every VON show. This provides Vendors, Developers and Service Providers a face-to-face meeting environment to resolve any issues that arise from tests performed within the standing environment. It also presents a forum for participants to announce successful interops and demonstrations. In conjunction with the standing environment, the "Pavilion Version" allows participants to create end-to-end demonstrations of IP communications. Participation is open, like the network itself, to any qualifying vendor in the VoIP community. The requirements for participation in the Pavilion Version is that a vendor have a presence in the Standing Environment and that they also have a booth at the pulver event at which the OTN is implemented.
A "Table-Top" Version of the OTN will travelt to smaller Pulver events where space does not permit a Pavilion Version. At a table-top version, only end-user devices will travel to the the show. All infrastructure equipment and software in the Melville Lab will be accessed via the Internet in order to demonstarte interoperability.
