Line Protection and Restoration

Metrobility Line Protection and Restoration (LPR) product family incorporates a patented* redundant interface which provides redundant data paths for high availability networking. An essential connectivity tool for high priority and mission-critical applications, it provides fully redundant data paths for Ethernet devices. If the primary connection fails due to a cable or hardware failure, the LPR interface switches the device's traffic to the secondary connections within 200 microseconds.

Equipped with SONAR, or Switch on No Activity Received, the interface not only monitors for loss of link on the active port, but will also monitor for traffic. With SONAR, if the active port remains idle for a given amount of time (configurable for 1-31 seconds) the resilient technology of the redundant interface will verify activity on the secondary port, and switch traffic to that port once traffic is detected. This prevents a switch or switch port failure from bringing down the any part or all of the network.
