Chapter 4 Staging Area Considerations
Using the frequencies in this appendix vastly improves the speed and performance
of the initial staging process.
After a DHCT has been successfully downloaded using the CVT download method,
the DHCT retains the frequency of the carousel for subsequent downloads and,
therefore, does not search for the frequency again.
What Are the Recommended Frequencies?
We strongly recommend that you configure at least one QAM modulator to use one
of the recommended frequencies shown in the following table.
Important:
These are the channels and frequencies that the DHCT checks first during
staging. If you use other frequencies, then the DHCT is forced to scan all possible
frequencies until it finds the correct frequency.
Although additional scanning increases the time needed to download software,
the CVT download method operates at all STD, IRC, and HRC frequencies.
Because the CVT information is loaded into all QAMs, or those selected as
staging bridges, the selected QAM does not need to be the QAM used to carry
the BFS sessions. You may select from any of the QAMs configured in your
network.
