Reset QPSK Modulators
Important Notice Regarding the Reset of QPSK Modulators
On occasion, for testing purposes, default configuration files for headend
components are changed. For example, a site might substitute a file called
qpskC70.config, instead of qpsk.config, for the QPSK configuration file. If the site
you have upgraded uses a custom configuration file, and if you are now ready to use
the default configuration file again, you need to update the configuration file
settings for your headend equipment.
The default configuration file for the QPSK modulator is /tftpboot/qpsk.config.
