The existing diagram is under general revision. Hellas-FRN.net now has a separate DMR server for digital networks, globally connected, which is currently under development to include all known digital networks with the corresponding connections. A detailed illustration of analog and digital connection bridges will be posted on this page, replacing the current one. At the moment you can be informed about the progress of the development of the digital network at http://2022.adn.systems , under the name ADN-HELLAS-FRN, a purely (nature and location) Greek server.
