Self-monitoring and redundant systems
Ultimate Reliability
Symphony PlatformIn critical situations, every second – and every word – counts. Commend systems are designed specifically to ensure that every single call gets through, no matter what. Always, without exception. This is why Commend systems monitor their own functionality:
- Line Monitoring checks the connections between the Intercom stations and the Server.
- The Intercom stations run continuous tests on the signal path between their loudspeaker and microphone. More
- Self-testing buttons for critical functions perform regular button activation simulation tests (special buttons are required).
- To protect Intercom stations against vandalism, sabotage detection switches will trigger an alarm at the Control Desk if the device is tampered with.
- Server monitoring and redundancy ensure the required high availability.
Promises you can rely on
- Full 24/7 availability.
- Control Desk staff are immediately notified in the event of a problem (e. g., extreme vandalism) to enable instant troubleshooting.
- Very low system inspection requirements – no need for manual testing (saving time and costs).
Software Intercom Server VirtuoSIS
Entire virtual environments can be backed up and migrated reliably without interruptions. As a result, scheduled downtimes are a thing of the past. After an unscheduled downtime, connections and functions are restored within a very short time.
Ultimate availability ‒ ultimate security (Mirroring*) *Mirroring: VMWare Enterprise Edition provides a Fault Tolerance (FT) function to ensure continued availability for all applications in case of a server failure.
Server redundancy for hardware-based Intercom Servers
- Intercom stations can connect to up to three servers simultaneously.
- Calls are transmitted via the active server.
- Fallback servers within the network allow for reliable redundancy arrangements. In the event of a server or router failure, call connection will be re-routed automatically via the available servers.
- Multiple power supply units ensure a redundant supply of operating power. This way, the Server will continue to operate uninterrupted even if a power supply unit fails.
Server redundancy for SIP capable systems
- Intercom stations can connect to up to three servers simultaneously.
- Calls are transmitted via the active server.
- In case none of the servers can be reached, the system can try to establish a serverless connection as a last resort ‒ e.g., by setting off a call to all Intercom stations on the network. Of course, this is also supported by serverless systems.
High Availabilty
Every single call gets through,
no matter what.
