Updating software images in binary format require the use of a TFTP server. The TFTP server
stores the files which will be downloaded to your modem. This guide assumes that you have
correctly set up your TFTP server on the same subnet as the modem and that the appropriate
files are available to download.
When updating software remotely, file corruption is a major concern. For example, if an image
file altered during the TFTP process the modem may not restore its connections after a system
reset. To eliminate such possibilities, the modem software performs a CRC check for the
integrity of each file after it has been downloaded.
