The R850 appliance provides failover capabilities for digital (T1, E1,
J1, PRI, BRI) circuits. Lines from the telephone company are terminated
to the R850, which then delivers service to Digium interface ports on
the active server. In the event of a hardware or software fault on
primary, the R850 redirects all circuits to the backup. Control
signaling is handled via USB ports which also provide power to the R850,
saving energy over the lifetime of the appliance.
R-Series appliances include all the tools necessary to build a fully redundant active/passive communications solution. If the primary server experiences a hardware or software fault, all telecom services will automatically switch to the backup server. The R-Series integrates with software to mirror file systems, manages the transition of a shared IP address and monitors system health between the primary and backup.
