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. bero*fos 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 bero*fos, a solution device for Asterix Clustering and failover scenarios that requires a physical reconnection of analogue, BRI or PRI lines. Two failover scenarios, Failover and Bypass mode, are supported.
