Setting the Input Quality Level
Use the ED-SYNC command to set the quality level (QLEVEL) of the specified
input. You set the QLEVEL when using inputs that do not have an associated SSM,
or when you want to set an alarm threshold for inputs that have SSMs. The
QLEVEL determines the TimeProvider’s output SSM.
If you provision QLEVEL below the quality level of the local oscillator in the IOC,
then the TimeProvider disqualifies the input with the INPQL alarm. An INPQL alarm
also occurs if the incoming SSM indicates that the input signal is below the quality
level of the local oscillator or if the incoming SSM is below the provisioned level.
Normally, you provision the QLEVEL for each input to be either unique or all the
same. If you set all QLEVEL for inputs to unique values, then you have set up a
revertive switching strategy. If you set all inputs to the same value, then you have
set up a non-revertive switching strategy.
ED-SYNC:[<tid>]:<aid>:[<ctag>]::<keyword>=<value>;
This command has a default access level of ADMIN.
Sample Commands
ED-SYNC::PRS:::QLEVEL=1;
ED-SYNC::INP1:::QLEVEL=1;
ED-SYNC::INP2:::QLEVEL=1;
This series of commands sets the QLEVEL for all inputs to the same level; if you
also provision the PRIORITY level to the same value, then you have set up a
non-revertive switching strategy.
