Disasters in a communication network are often very difficult to predict and there is usually a very small advance notice when a communication line goes down. The beroNet Failover Switch (BNFOS) provides an effective way for dealing with such unexpected events by re-routing the lines to a back-up line when undesirable changes are detected. Therefore beroNet provides beroNet Failover Switch, a solution device for PBX Clustering and failover scenarios that requires a physical reconnection of analog, BRI or PRI lines. In addition to this properties, the Failover Switch has two individually switchable powerports on the rear panel, for remote power on /power off or reboot the respective connected devices. The beroNet Failover Switch can be used in two scenarios, the failover scenario or the bypass scenario.

Description Model
Failover Switch (EU) BNFOS
Failover Switch (USA) BNFOS110

Failover Scenario
The failover scenario grants the smooth and reliable operation of two PBXs side by side, where the second one will be switched to active only after the failure of the first one in order to reduce downtime to a minimum (see figure). This scenario is not only interesting in failure situations, it could also be used in cases of maintenance, repair or upgrade of your telecommunications equipment.

ISDN Failover Switch

Bypass Scenario
The bypass scenario is interesting for customers who want to keep their old telephone system and add new functionalities by adding a new PBX in front of the old one (e.g. by an Asterisk system). With the bypass scenario you have the opportunity to add a new PBX between the PSTN Lines and the outgoing Lines of the old PBX system. In the case of a failover, the PSTN Lines will transparently reconnected to the existing old PBX (see figure).
