The diag 5 server at the Practice site sends evaluations via the Internet to the diag 5 server. The server at the head office must be accessible via the Internet at a publicly accessible address.
The diag 5 server of the Practice regularly checks via the Internet whether evaluations are available for download on the server in the central office
The server in the head office does not actively operate in the rdt system, it merely provides an interface via the publicly accessible address, which custo systems can use to exchange evaluations.
