This approach allows you to build simple 1+1 systems up to more complex N+1
systems. This system can also control groups of 1+1 or N+1 systems.
Redundancy groups are independently controlled.
Switching can be done automatically and/or manually by means of the front panel or
remote monitor and control. Although the switching system is a perfect match for
ST Engineering iDirect equipment, other non-ST Engineering iDirect equipment can be
handled as well. The definition of the switching logic and used modules is called a
“configuration”.
When the automatic mode is activated, the redundancy system monitors the alarm
contacts of the active downconverter. When an alarm is detected, the input and output
signals are switched, effectively rerouting the input and output signals to the spare
downconverter. The fast switching ensures a minimal service interruption.
