Config 1 and Config 2
Use the radio buttons to specify the
SDI
input for each of the four
Fiber
outputs.
Select
Laser Off On Inp Err
to apply a mute to the output if there is no valid signal on its input as
defined by the checkboxes; includes signal lost. Select
Laser Off
to manually apply a mute to the
output.
Swap Config 1 <> 2
Click
Swap Config
to swap the Config 1 setup with the Config 2 setup.
Mode
These controls specify which configuration is to be used, or whether the configuration choice
should be made by the rules configured in the
Rules
section.
Primary & Secondary Inputs
Use the radio buttons to select which input channels are used in the
Rules
section.
Rules
These controls specify which configuration is to be used if the
Use Rules
option is selected in the
Mode section. The option enables the configuration to be switched automatically if an input fails or
changes to an inappropriate rate.
•
Config 1 On Primary Input OK:
this selection will use Config 1 if the Primary Input is
receiving a valid input signal.
•
Config 2 On Primary Input Err:
this selection will switch to Config 2 if the Primary Input 1
is not receiving a valid input signal.
•
Config 1 On Secondary Input Err:
this selection will switch to Config 1 if the Secondary
Input is not receiving a valid input signal.
•
Primary Input Delay for Rules
•
OK Timer:
this specifies the time that the Primary Input must be receiving a valid signal in
order to be considered ‘OK’ by any rules.
•
Err Timer:
this specifies the time that Primary Input must be receiving an invalid (or lost)
signal in order to be considered in error by any rules.
•
Secondary Input Delay for Rules
•
Err Timer:
this specifies the time that the Secondary Input must be receiving an invalid (or
lost) signal in order to be considered in error by any rules.
NOTE:
Because the reclockers that measure the rate of the signals are on the
outputs
rather than
the
inputs
of the routing cross-points, an input must be routed in order for its rate to be determined.
Therefore, depending on which Rules are selected, the Primary and/or the Secondary input
channels have to be routed in one or both of the two configurations in order for the rule to work…
•
Config 1 On Primary Input OK:
Because this is a rule for switching from Config 2 back to
Config 1, the Primary must be routed in Config 2.
•
Config 2 On Primary Input Err:
Because this is a rule for switching from Config 1 to
Config 2, the Primary must be routed in Config 1.
•
Config 1 On Secondary Input Err:
Because this is a rule for switching back from Config 2
back to Config 1, the Secondary must be routed in Config 2. Also, to prevent the
configuration switching backwards and forwards between configurations, it must also be
routed in Config 1.
