Status
Shows the current redundancy status, either:
Main – inputs are routed from the main input source
Backup – inputs are routed from the backup input source
Click Switch to change the current active input. If the current active input is Main, the input source will switch to
Backup and vice versa. For port-based input redundancy entries, an additional Remove button is visible. Click
Remove to remove the port for which input redundancy is configured.
12.1.1 CONFIGURING SERVICE-BASED INPUT REDUNDANCY
Service-based redundancy is set up under the Outputs node. Double click on a service of your choice to access
the Service Properties dialog. Under the Input Redundancy section, select the appropriate parameters.
The following parameters are available:
Backup source
Assign a backup service; choose None to disable input redundancy.
Switching mode
Select a suitable mode for each redundancy pair. The following modes are
available:
Off – Stop switching whether it is on main or backup
Once – Switch from main to backup when an alarm occurs on main and remain
there
Floating – Switch when an alarm is set on the service that is active, ignore clear
alarms
Reverting – Switch to backup only if there is an alarm on main but not on
backup; switch back when alarms on main are removed or set on backup (this is
the recommended mode).
1. Input redundancy on Scrambled MPTS inputs must be configured carefully. This is because if
the input must be descrambled it is not possible to select different descrambler modules for
each service (main and backup). In other words, all inputs to the descrambler must be routed
from the same input source. Currently the system does not enforce this requirement; hence it
is recommended that caution be exercised when combining descrambling with input
redundancy.
