The R800 appliance provides failover capabilities for analog (POTS) circuits. Lines from the telephone company are terminated to the R800, which then delivers service to Digium interface ports on the active server. In the event of a hardware or software fault on primary, the R800 redirects all circuits to the backup. Control signaling is handled via USB ports which also provide power to the R800, saving energy over the lifetime of the appliance.
