If the Rate Control was set to User, enter the maximum output bit rate in the
User Rate field. This setting is used when the signal source is RF or ASI and
allows you to set the output bit rate to a value expected by equipment connected
to the ASI output.
You can enter a range from 0 to 206 Mbps.
Note: Output data may be lost if this bit rate is set to a value less than the actual
signal bit rate.

From the Output Mode drop-down list, choose the DPM output mode for the
current output. With the exception of No Output and Full DPM Control,
selecting a mode will configure the DPM settings to achieve the specified
behavior. In this way, they act as DPM presets. The Mode Status is changed
from Unmodified to Edited by User. We highly recommend that you use either
one of these basic modes, or, for advanced setup, enter the DPM mapping before
setting the Output Mode. The following table describes each mode:
Output Mode
No Output
Passthrough
Service Channels

MAP Passthrough

Description
The output rate follows that set by the uplink. The output rate will
be the same as the input rate (including all null packets). This
means the output bit rate is determined automatically based on
the input source symbol rate and FEC value.
The output rate is specified by the User Rate field. It is determined
by the user setting regardless of the input source.
Description
No ASI output will be generated and the ASI port will be disabled.
All PEs will be set to Pass and other DPM settings will also be set.
This is similar to Passthrough, except that only channels applied
to program entries are available on the output.
The output will be identical to the input, except that channels
assigned to PEs and PIDs will be mapped using the DPM settings.
If the input is tuned to a valid channel, the PEs are automatically
set to Map. Otherwise, the PEs are automatically set to Drop.
Note: If the PE is mapped, it uses the last saved output MAP
configuration. The output map (for example, output channel PMT)
does not change automatically if the input or channel number is
changed.
This is similar to MAP Passthrough, except that only channels
applied to program entries are available on the output. If the input
is tuned to a valid channel, the PEs are automatically set to Map.
Otherwise, the PEs are automatically set to Drop.
Note: If the PE is mapped, it uses the last valid input. The output
map (for example, output channel PMT) does not change
automatically if the input or channel number is changed.
