Digium R850 Information:
Digium’s Redundancy Series (aka “R-Series”) products, are a family of inexpensive, versatile appliances that enable physical layer failover of analog (POTS) and digital (T1, E1, PRI or BRI) telephony connections to Asterisk-based communications systems. The R-Series devices allows Asterisk administrators to create high-availability solutions that insure uninterrupted business communications, even in the event of a catastrophic hardware or software failure.
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.
The R-Series family consists of 2 models, the analog R800 appliance and the digital R850 appliance. Each model supports eight (8) public switched telephone (PSTN) circuits. The appliances delivers PSTN circuits to each Asterisk server via Digium’s telephony interface cards. Management and failover communications between the Asterisk Servers and the R-Series appliance is done using a set of USB connections, which also provide power — saving energy costs over the lifespan of the appliance.
Business communications are critical. Trust Digium, the creators of Asterisk, to provide the most reliable and robust solution for mission critical Asterisk solutions.
