Tuning Adapter Configuration File
You can configure the Tuning Adapter using a configuration file (trconfig.tbl). This
configuration file is only necessary when your network setup is different than the
default Tuning Adapter configuration, such as in a non-SARA environment or in an
Overlay
TM
environment.
To use a different Tuning Adapter configuration, you must create a configuration
file and place it on an out-of-band BFS carousel for use by the Tuning Adapter
population.

You can provide a separate configuration file for each hub. You can also assign
channel maps (maps that are not tied to a physical or default hub) to the Tuning
Adapter using Enhanced Channel Maps. Refer to the Enhanced Channel Maps User's
Guide (part number 4011413) for information on how to define group definition rules
and lineup groups (LUGs). The Tuning Adapter supports both virtual hub and LUG-
based enhanced channel maps.

If present, the Tuning Adapter loads the configuration file when it boots and
monitors the configuration file once a minute for changes. This monitoring includes
checking for an added configuration file (if one was not originally present at boot
time) and checking for removal of the configuration file from BFS if it was originally
present. The Tuning Adapter reverts to the default configuration if the configuration
file is removed from the BFS and a new configuration file is not added to the BFS
within 24 hours.
