TwinStar CompletePBX Server Redundancy
Award-winning solution providing rapid failover for the entire CompletePBX telephony solution
The TwinStar configuration (P/N CTS2000, CTS3000, CXTS3000 or CTS4000) is a bundled product, comprised of two module-less servers, based on the Xorcom CXE series IP-PBX, that have been optimized for use as a failover system.
TwinStar System Description
TwinStar provides full redundancy for a complete PBX system, including telephony interfaces. A sophisticated automatic replication and detection mechanism located in the Astribank detects server failure and switches all telephony to the backup server, keeping downtime to an absolute minimum. The firmware-based switching mechanism is not network-dependent.
How to Determine the Right TwinStar Redundant Server Configuration for Your Implementation
The servers used in the TwinStar configuration are either the CXE2000, the CXE3000, the CXT3000 or the CXE4000. The first meets the requirements of smaller installations, supporting up to 200 users and 45 concurrent calls. The second and third are more robust, supporting up to 1000 users and 480 concurrent calls. The latter is meets the highest call volume requirements, supporting up to 1500 users and 750 concurrent calls. To complete the configuration, select the relevant Astribank model(s) based on the telephony interface requirement (the number of analog and digital ports and trunks to be supported). The easiest way to determine the configuration is by using the PBX Configuration Wizard.
Two identical CompletePBX servers are connected via USB 2.0 to an Astribank. The Astribank firmware replicates the server data in real time, performs failure checks, and switches all telephony control to the backup server, if necessary.
