Independent Mode.
Either one or both output ports can be configured as an output.
No switching is done between the output ports. If two outputs are employed then
they are totally independent of each other
Autonomous Mode.
Both outputs are used but only one at a time. Redundancy
switching is done between the two outputs.
Mirrored Mode.
Both outputs are used at the same time. The same data appears
on both the output ports.
E.2
Program Level Redundancy [PLR]
E.2.1
Scope
The following components support the Redundancy Modes:
•
MX8400 Multiplexer Main Card
•
MX8400/HWO/PROFEC RJ-45 Ethernet Card with ProMPEG FEC
•
Program Level Redundancy is applied at unit level.
E.2.2
Overview
E.2.2.1
Problem
Previous to Software Version 5.0.0, only automatic link level redundancy was
offered. This allowed autonomous switching to a secondary (back up) network
connection in the event of a physical link loss on the primary network. All traffic is
then routed via the secondary network with no intervention from the nCC. This
results in a large disruption to all active programs.
E.2.2.2
Functional Description
Software Version 5.0.0 introduces Program Level Redundancy (PLR). If a single
transport stream (or program) fails to be carried in the primary network, it can be
received from the secondary network (back up) without affecting all other active
programs.
