The SSCF and SED configuration files stored in the modem contain all of the satellite parameters the TracPhone system needs to find and track the mini-VSAT Broadband satellites. These configuration files need to be updated whenever changes are made to the satellite network. In most cases, the modem will download the latest files automatically via the satellite link.
However, if your system does not operate within the mini-VSAT Broadband coverage area during the download period (several weeks), your modem might miss the update. In such cases, the modem needs to be updated manually (see Manually Updating the Modem Configuration Files).
