To increase uptime, large cable head end stations use motorized antennas as mobile redundancy. If a stationary antenna fails, a redundancy switch assures the satellite signals are routed via the mobile backup antenna. Until recently, DEV Systemtechnik offered a two-part solution for this task, consisting of two appliances of 3RU each. Now DEV is the only vendor to integrate the complete functionality into one single 3RU chassis. The new solution is faster and more robust  than its predecessor, and costs 25 per cent less. The combination of the antenna monitoring and control system DEV 9110 and the redundancy switch DEV 1993 offered operators a convenient way to manage their motorised redundancy antenna via a user-friendly web interface as well as for the automatic switching of signal paths from the stationary to the mobile antenna. A microcontroller communicates with the antenna controller of the redundancy antenna and enables the manual or automatic positioning of the antenna. The appliances can be attached to the head end station’s network management system via SNMP. The complete solution is now DEV 1993 Option 30 in DEV Systemtechnik’s portfolio — DEV 9110 is obsolete and no longer available. Website.
