The "redundant twister" is an essential connectivity tool for high priority and mission-critical application. It provides fully redundant data paths, as well as power supply redundancy for Ethernet or Fast Ethernet devices. If the primary connection fails due to a cable or hardware failure, the "redundant twister" instantly switches the device's traffic to the secondary connection.??Intelligent "redundant twister" modules also deliver Managed Network-on-Demand capability for mission-critical applications. Managed Network-on-Demand allows the "redundant twister" media converter to be configured to operate in either Dynamic Recovery Mode (DRM) to ensure session integrity and increase uptime, or in Network Select Mode (NSM) to redirect traffic and add security through link isolation.
