Figure 10.15 – Output Redundancy Port Settings
The Port Settings parameters have been described in detail in Section 7.4.
The following Output Redundancy parameters are available:
Source IP When OSPF is used the source IP should be defined.
If not set then the IP address of the Dataport will be used for all
streams. The effect that a single stream failure will disable all
sources.
The Source IP address set here should correspond to the Source
IP address of the other stream source.
Output Redundancy The output redundancy logic may decide to stop an output due to
some conditions. One reason could be that a service failed to be
descrambled. If this service is the only service being transmitted on
an output the choice is simple: the system can easily just stop the
output.
On the other hand, if the output is an MPTS containing 10
services, for example. Then the choice is not so simple should one
failure result in all 10 services to be stopped on the output.
The redundancy control option lets the operator decide which
conditions should be met in order for the output to be stopped.
Choose one of the following options:
All – all services must fail
Majority – only majority services must fail
One – one service failure is sufficient
None – automatic redundancy is disabled
These switching rules apply to the services with the highest priority
ranking within the Output TS.
For more information about service priority, refer to the service
configuration property page.
