The WORK Microwave redundancy switch 1:1 is used for 1:1 redundancy configurations for Upconverters, Downconverters, Modulator-Upconverters, Transport Stream Modulators, Demodulators, and Modems. It comes standard with a coaxial signal switch for the input signal and a coaxial signal switch for the output signal. For IP modem applications a similar device, RSCI1 is available.
LNAs or even HPAs can be included within the system, as the switch is capable to control external waveguide transfer switches as option. DC power to LNAs can also be provided as option. The switch accepts alarm signals from two types of equipment, so that it can be used for redundancy configurations with e.g. a video encoder and a modulator within one chain.
The unit can be controlled from the front panel or remotely via RS 232, RS422/485, or IP over Ethernet. The unit can operate in automatic mode, whereby an automatic switchover to the standby unit is performed upon detection of an alarm generated by the active unit. In addition, a manual switchover to the standby unit can be initiated.
Two power supplies and two AC input connectors guarantee high availability of the unit. The 1:1 redundancy is also available in an outdoor version, where the signal transfer relays are mounted within an outdoor switch box. The control unit is similar to the indoor redundancy controller, but does not include any signal switches. The outdoor switch box also includes interfaces for alarms and M&C of outdoor units. A control cable runs from the outdoor switch box to the indoor redundancy controller.
