Modulator Configuration
– Modulator Parameters (Failover)
Failover:
This field
provides options to enable a Backup Input in the event of a Primary Input
fault. Failover and Restore selection must to applied, after changes select the Apply Changes
field and press the ENTER front panel key.
Failover to backup options include:
Primary Sync Loss
Primary TS Error
Manual Only
TS Sync Loss mode allows the SMD 989 to switch to
backup if the primary input transport sync is lost. In
the TS Analysis mode failover is based on transport
stream errors or sync loss. This allows the SMD 989
to switch to a backup source when there are errors in
the transport stream even if it does not lose sync.
Restore
: This
field defines the conditions which direct the modulator to return or switch back to
the primary input.
Restore
to primary options include:
Primary TS Sync Restored
Backup TS Sync Loss
Primary TS Error
Manual Only
Primary TS Analysis Restored
Backup TS Analysis Failure
The restore to primary options depend on the Failover
setting. If failover to backu is TS Sync Loss, restore
can be set to Primary TS Sync Restored, or On
Backup TS Sync Loss. The switchover Interval(s) can
be set from 1 to 20 seconds. If switch to Backup is set
to Manual, Restore to Primary can only be set to
Manual.
If
TS Analysis Failure (option)
is selected, Restore
options are Manual Only on Primary TS Analysis
Restored or On Backup TS Analysis Failure.
Failover conditions can be enabled/disabled and Switch After interval can be set from 1 to 30
seconds.The switch after intervals for each of the TS analysis categories defines a wait time or
delay before the modulator switches to the backup or switches from backup to primary when TS
analysis errors are detected. If the TS Errors are corrected within this time the switch is not
implemented and the TS analysis resumes.
IMPORTANT NOTES: 1. When selecting TS Analysis Failover for Primary or Backup inputs,
the TS Analysis feature must be enabled or active for the respective primary and/or
backup. See the TS Analysis Configuration menu.
3. You cannot use the TS Analysis for failover when you are setup to output VCM or
CCM Multistream with the SMD910 modulator.
