E.2.3 Monitoring and Switching
E.2.3.1 Monitoring
PLR monitors for missing multicasts only
Both primary and secondary networks are continuously monitored
Multicast present status is known for both primary and secondary networks
For all input multicasts in the active profile, IGMP joins are performed on both
the primary and secondary networks.
E.2.3.2 Automatic Switching
If a multicast of a transport stream is missing from the primary network and it is
available on the secondary network, an automatic PLR is performed
If the current network fails, the MX8400 will switch all multicasts to the
secondary network
By default, the program will remain on the secondary network connection after a
switch
PLR auto-revert can be enabled using Static Parameters. This allows the
program to switch back to the primary network when the multicast returns
The auto-revert time set in the Static Parameters are applied
E.2.3.3 Manual Switching
The user can manually receive incoming multicast/s from a chosen network
using nCC
Manual selection of an input network takes precedence over the PLR input
network selection for a multicast
Note: PLR will switch back to the original input if a multicast is missing from the
manually-selected input network.
